The Radboleth must die.
The blast doors did not budge.
Mordecai Throgmorton stood before the control console, watching its amber warning lights flash in the dimness. Beyond the reinforced bulkhead, three of his friends were trapped with a monster that had already demonstrated an almost supernatural capacity for cruelty. Ahead of him, the reactor’s systems continued their inexorable countdown toward total failure.
He tried the manual override.
The console rejected it.
He tried again.
AUTHORIZATION INCOMPLETE. SECONDARY LOCK ENGAGED.
“Come on,” Mordecai muttered. “You ancient piece of junk. Open the damn door.”
Arkadiusz crouched beside him, examining the console’s interface while Paul Best loomed behind them. The Venusian’s armored silhouette filled much of the narrow corridor.
“How long?” Paul asked.
“Until what?”
“Until this place turns into a radioactive grave.”
Mordecai looked at the countdown, his massive hands flexed restlessly.
“Too long to waste standing here. Not long enough to feel comfortable.”
He began working through the system’s command architecture, looking for an administrative pathway that might bypass the physical locks. Arkadiusz examined the emergency controls. Paul checked the bulkhead’s perimeter, searching for a maintenance hatch, a manual release, anything that might offer another way through.
There was nothing.
The emergency doors of Sector 7G had been built for a civilization that understood the terrible consequences of a reactor containment failure. Their outer shells were reinforced with layers of duralloy and radiation-resistant ceramic. Hydraulic pistons drove massive, interlocking rings into the surrounding frame. Once those rings engaged, the doors became part of the building’s structure.
They were not designed to be persuaded.
They were designed to remain closed when everything else had failed.
And everything else was failing.
On the other side of the bulkhead, Noelani, Garet, and Vulgaris faced a different problem.
The giant amoeba occupied almost the entire width of the flooded corridor. Its translucent body shimmered beneath the emergency lighting, a vast, gelatinous mass of greenish tissue through which indistinct internal structures drifted like drowned organs. It had no obvious face, no recognizable limbs, and no discernible means of distinguishing one target from another.
It simply moved toward them.
Behind the Knights, the Reactor Core chamber glowed with an unnatural green radiance. The fusion core itself remained partially visible through a forest of protective conduits, its light pulsing at the center of the facility like a captured star.
The Knights were trapped between two kinds of death.
One approached them through the water.
The other waited behind the walls.
The Radboleth had separated them.
And time was running out.
Noelani raised her hands toward the sealed bulkhead.
She had heard the old stories since childhood. Ancient words, passed between generations, that could persuade stubborn things to release their hold. A chain might fall open. A shackle might loosen. A welded door might surrender its grip.
She spoke the chant.
For a moment, pale light flickered across the metal.
Then the light faded.
The door remained shut.
Noelani stared at it, unwilling to accept the answer.
She tried once more.
Nothing.
The locking rings were too massive, the hydraulic mechanisms too deeply engaged. Her power could loosen a fastening, but it could not command a fortress of interlocking steel to cease being a fortress.
She lowered her hands.
“It’s not going to open.”
“Then we stop asking it to,” Garet replied.
He turned toward the approaching amoeba and extended his arm.
The water around him shimmered.
Nanites poured from his supply, multiplying and assembling themselves into a shape that took form in the space between the Knights and the monster. A humanoid figure emerged, broad-shouldered and powerful, with the head and upper body of a man. Beneath the waist, however, its form changed abruptly. A muscular tiger shark’s trunk and tail completed the construct, its gray skin marked by dark stripes and rows of sensory pits.
The creature flexed its hands.
Then its tail swept through the water.
Garet gave it a silent command.
The construct surged forward.
Its first strike disappeared into the amoeba’s gelatinous mass. The blow displaced a tremendous quantity of water, sending suspended debris tumbling down the corridor. The creature shuddered but continued advancing, apparently unconcerned by the assault.
Garet changed tactics.
He focused his nanites on the iron molecules within the center of the amoeba’s body.
The microscopic machines flooded inward, attacking the metal-bearing compounds embedded in the creature’s unnatural tissues. For a brief instant, the amoeba’s interior flashed with a dull, rusty discoloration. Its mass contracted violently, rippling outward from the point of attack.
The creature recoiled.
Garet watched for signs of collapse.
There were none.
The damaged tissue flowed back into place. New layers of translucent material filled the disrupted region, swallowing the evidence of the attack.
“Of course,” Garet muttered. “Why would anything down here be easy?”
The amoeba struck.
Its enormous body swung sideways with startling speed. Vulgaris twisted out of its path, the edge of his Depthstrider suit passing within inches of the gelatinous mass.
The creature slammed into the opposite wall.
The impact shook the corridor. Loose panels tore free, and a cloud of sediment erupted around its body.
Vulgaris raised his Mark VII blaster.
He fired.
The bolt punched through the amoeba, leaving a blackened cavity that closed almost immediately. The creature continued forward, its internal currents flowing around the damaged tissue as though the wound were merely a temporary inconvenience.
Then the amoeba’s surface erupted.
A cluster of fleshy polyps thrust outward, each swollen tip releasing a burst of radioactive slurry.
Vulgaris took the attack across his chest.
The impact drove him backward. Greenish fluid splashed across his armor and helmet, spreading over the suit in a corrosive film.
His helmet filled with alarms.
SUIT INTEGRITY COMPROMISED.
RADIATION SHIELDING DEGRADED.
SEAL FAILURE: LOCALIZED.
Vulgaris looked down at the damage. The outer layer of his suit had begun to blister and peel beneath the radioactive contamination.
“That’s not good,” he said.
“No,” Noelani replied, watching the amoeba swell to fill the corridor. “It really isn’t.”
On the opposite side of the bulkhead, Paul finally found something useful.
The console displayed a set of authorization requirements buried beneath layers of emergency protocols. He pulled up the relevant instructions, then read them again.
His expression changed.
“What?” Arkadiusz asked.
Paul stepped aside so the others could see.
The blast doors operated under a security principle called the Two-Man Rule. In the Ancients’ final decades, they had learned that even the most sophisticated automated systems could fail, and that human judgment could become dangerously unreliable under pressure. Critical containment systems therefore required redundant authorization.
Two unique physical keys.
Two separate authentication channels.
Both keys turned within a three-second window.
Anything less triggered a tertiary lockdown.
“One key does nothing,” Paul said. “It doesn’t matter how much authority the computer recognizes. Without the second key, the doors stay sealed.”
Mordecai’s face hardened.
“We have one.”
“The one from the skeleton in the water-treatment tank,” Arkadiusz said.
Paul nodded.
“And we don’t have the other.”
“Then we find it.”
“Where?” Paul demanded. “The computer isn’t telling us. It doesn’t even know where the key is. For all we know, it’s at the bottom of the lake.”
Mordecai turned toward the newly carved tunnel that branched away from the intersection. The passageway’s jagged walls were coated with the same sickly green residue they had encountered throughout the complex.
The Radboleth had torn through the facility on its way to the reactor.
It had left a trail of destruction that was also a map.
“We go around,” Mordecai said. “Through its tunnel.”
Paul glanced at the countdown.
Then he looked at the sealed bulkhead.
“Fine. But if that computer decides to shut down before we get back, I’m going to haunt whoever designed it.”
“Get in line,” Arkadiusz replied.
They turned east and began moving.
The amoeba hesitated.
Its outer surface contracted, then expanded again.
The Radboleth, however, did not hesitate.
A shadow moved beyond the Reactor Core, where the corridor bent toward the reactor chamber.
A vast mouth opened in the darkness.
Noelani turned.
The Radboleth was there.
Its tooth-lined maw seemed too large for its body, an obscene crescent of pale flesh and black gums. Tentacles unfolded around it, probing the water with a terrible deliberateness. Its eyes reflected the green radiance of the reactor, giving it the appearance of something that had swallowed pieces of the dying star and learned to hate the world.
It attacked without warning.
A tentacle struck Noelani’s shoulder. Another caught her across the waist. A third whipped around the back of her helmet and slammed her against the corridor wall.
Her suit absorbed the worst of the impacts, but the force was immense. The water around her burst into turbulence, and her vision flashed white as her helmet struck the metal plating.
The Radboleth drew her toward its mouth.
Noelani planted her boots against the wall and fought the pull.
She brought the ColdSteel Gunstock War Club around in a brutal arc, striking the nearest tentacle. The blow landed with a deep, muffled impact. The appendage recoiled, its surface splitting along a line of dark tissue.
Noelani wrenched herself free.
She moved faster.
For several seconds, her movements seemed to outrun the water itself. She twisted past another tentacle, struck the Radboleth across the jaw, then drove the heavy weapon into the side of its head.
The creature recoiled.
She struck again.
Then she withdrew toward Garet and Vulgaris, unwilling to let the monster draw her away from the others.
Garet saw the opening, and had been saving his most dangerous trick.
He extended his hand, and the nanites responded.
The water ahead of the Knights changed.
Oxygen molecules vanished from a broad section of the corridor as the nanites removed them from the surrounding environment. A nearly invisible oxygen-depleted boundary formed between the Knights and the Radboleth, a zone in which anything dependent on oxygen would rapidly begin to suffer.
The creature swam straight through it.
The lack of oxygen should have crippled it. Instead, it passed through the zone with only a momentary hesitation, its tentacles moving in slow, controlled sweeps.
It had adapted to the situation.
The Radboleth emerged from the barrier and lashed out at Garet.
A tentacle struck his chest.
His suit lurched backward, and its warning indicators flashed from green to amber.
Garet caught himself against the wall.
“That’s becoming a habit,” he said grimly.
The amoeba surged forward again.
Its polyps erupted in a fresh barrage, showering the Knights with radioactive fluid. Garet’s construct interposed itself between the creature and its creator, absorbing the worst of the impact. Its synthetic flesh blackened where the slurry touched it, but the construct held its position.
Vulgaris fired again.
The Mark VII’s energy bolt carved a glowing channel through the amoeba. The creature shuddered and rolled, its mass striking the ceiling before sliding back into the corridor.
Noelani watched it carefully.
The amoeba was not invulnerable.
It was simply very difficult to kill.
And the Radboleth was still pressing its advantage.
The eastern corridor opened onto the crossroads.
Mordecai reached the corner first.
He stopped so abruptly that Paul nearly collided with him.
Three enormous masses of pinkish-red protoplasm drifted through the intersection. Their surfaces shimmered with iridescent colors, and pale currents moved through their translucent bodies like blood through a living circulatory system.
Cleansing Slimes.
The creatures occupied the passageway with the silent confidence of predators that had never encountered anything capable of threatening them.
One of them extended a tendril.
The appendage struck the wall beside Mordecai, leaving a trail of pitted metal and dissolving organic residue.
Arkadiusz reacted first.
He fired into the cluster, then launched a grenade at close range.
The explosion illuminated the crossroads in a brief, violent flash. All three slimes convulsed, their bodies collapsing inward before expanding again. Fragments of gelatinous material scattered across the corridor, sizzling against the metal floor.
Arkadiusz moved immediately, firing again before the creatures could recover.
Something changed in him.
His movements became sharper, more economical. His aim settled with uncanny certainty. He seemed to anticipate the slimes’ motions a fraction of a second before they occurred.
A second shot struck one of the creatures across its central mass, opening a ragged wound that failed to close completely.
“Keep moving!” he shouted.
Mordecai pushed forward, bringing his Mark XII blaster to bear. The weapon discharged repeatedly, each shot sending violent ripples through the nearest slime.
Paul moved behind him, his Plasma Sniper Rifles already trained on the creature attempting to flank them.
The corridor became a killing ground.
One slime lunged toward Mordecai, its tendrils spreading across the passageway. He planted himself against the wall and fired point-blank into its advancing mass.
Paul fired at the same moment.
His plasma shot struck the second slime in its exposed center.
The creature convulsed violently. Its translucent body fractured into a cascade of crystalline shards, which drifted apart in the water before settling across the floor.
For an instant, the intersection was illuminated by the pale glow of its remains.
Then the light faded.
Arkadiusz exhaled.
“One down.”
“Two,” Paul corrected.
The remaining slimes were already moving toward them.
The Radboleth was weakening.
Garet had forced his way closer to the entrance of the Reactor Core chamber, where he could see the creature more clearly. He extended his arm and unleashed another concentrated wave of nanites.
The Radboleth’s body stiffened.
Moisture fled from its exposed tissues as the nanites attacked the water within its cellular structure. Its tentacles curled inward, and its massive body convulsed as the dehydration spread.
The creature’s movements became erratic.
Its mouth opened in a silent scream.
Noelani saw an opportunity to draw it away from Garet. She moved backward into the Reactor Core chamber, firing her Mark V blaster as she went.
The Radboleth followed.
It ignored Garet.
Ignored Vulgaris.
Ignored the nano construct that continued to harass its flank.
Its entire attention had fixed on Noelani.
She understood the danger. The creature had studied them throughout their descent, using traps, false floors, sealed doors, and carefully timed attacks to separate the group and exhaust their defenses. It had learned which of them would charge, which would retreat, and which would attempt to protect the others.
Now it wanted one of them dead.
Noelani kept firing.
The Mark V’s shots struck the Radboleth’s head and upper body, leaving smoking wounds in its flesh. It recoiled but continued advancing, dragging its tentacles across the floor of the reactor chamber.
Behind her, Garet moved into position.
He unleashed the Discombobulate effect.
The nanites swept through the water in an invisible wave, targeting the Radboleth’s neurological tissues and the delicate systems through which it perceived the world.
The creature’s eyes began to bleed.
Dark fluid streamed from its ears. Its tentacles spasmed uncontrollably, striking the walls and floor as its senses collapsed into a storm of pain.
For the first time since the Knights had encountered it, the Radboleth appeared afraid.
Noelani did not waste the moment.
She fired again.
The bolt struck the creature’s temple.
The Radboleth staggered.
She advanced, raised the ColdSteel Gunstock War Club, and brought it down against the side of its head.
Once.
Twice.
A third time, with all the strength she could summon.
The creature’s body lurched sideways.
Then it fell.
Its tentacles collapsed across the floor in a tangled heap of pale flesh. The immense mouth hung open, its teeth exposed in a grotesque parody of the grin that had haunted them throughout their descent.
Noelani stood over it, breathing hard inside her helmet.
For several seconds, nothing moved.
Garet approached cautiously.
“Is it dead?”
Noelani stared at the creature.
“I think so.”
The words felt inadequate.
They had spent so long hunting the Radboleth, so long watching it manipulate the complex around them, that its stillness seemed impossible. This was the creature that had turned an ancient reactor into a trap, that had separated the Knights and driven them toward the edge of annihilation.
Now it was a heap of dead tissue on a metal floor.
Vulgaris moved past them, his suit badly damaged but still functioning.
“Then let’s finish the rest of this nightmare.”
He turned toward the corridor.
The amoeba was waiting.
The remaining Cleansing Slimes had pushed Mordecai and Paul away from the jagged opening of the Radboleth’s tunnel. Mordecai fought with his back against the wall, pouring blaster fire into the advancing mass.
Paul’s plasma rifles struck the flanking creature repeatedly, each shot burning away another section of its body.
Arkadiusz found an opening and fired.
The shot struck the third slime, tearing a deep wound through its translucent surface. The creature recoiled, its body rippling violently, but continued to press forward.
Arkadiusz switched weapons.
The disintegrator beam struck the slime and disappeared into its mass, absorbed without producing the catastrophic reaction he had expected.
“Of course,” he muttered.
The slime advanced.
The nano construct appeared at the far end of the carved tunnel, its sharklike tail driving it through the water. It passed the fallen remains of the first slime and launched itself at the last surviving creature.
The impact sent the slime crashing into the wall.
Its body ruptured.
The construct struck again, tearing through the damaged tissue until the creature collapsed into a heap of inert crystalline residue.
The crossroads fell silent.
For the first time in what seemed like hours, there was no immediate threat between the Knights and their next destination.
Mordecai lowered his weapon.
“That’s the last one.”
Paul looked toward the reactor chamber.
“Then we regroup and finish the amoeba.”
They started moving.
Garet knew the amoeba was close to defeat.
Its translucent body had begun to lose cohesion. The earlier attacks had damaged it severely, and the construct had kept it under constant pressure. Still, it continued to strike at Vulgaris with frightening force.
A final barrage of polyps burst across the corridor.
Vulgaris took the attack directly.
The impact drove him backward, and the creature’s enormous body slammed into him before he could recover. Electricity flashed across the water, enveloping his suit in a web of blue-white arcs.
His body went rigid.
His blaster slipped from his hands.
He collapsed against the floor.
“Vulgaris!” Noelani shouted.
She started toward him, but the amoeba surged between them.
Garet moved first.
He reached Vulgaris and activated the repair nanites. They poured across the damaged suit, sealing ruptured seams and rebuilding the compromised outer layers. More nanites passed through the armor’s failing systems, repairing the damage to Vulgaris’s body.
For several seconds, nothing happened.
Then Vulgaris gasped.
His limbs moved.
He rolled onto his side and pushed himself upright.
Garet watched the suit’s integrity indicators stabilize. The outer shell sealed behind the repair process, cutting off the nanites’ access to Vulgaris’s body.
“Stay down,” Garet advised.
Vulgaris reached for his rifle.
“Absolutely not.”
He raised the Mark VII and fired.
The shot struck the amoeba’s center, burning a deep channel through its translucent body. The creature shuddered, its internal currents faltering.
Garet lifted his hand.
The nanites assembled into a tight, directed sonic beam. The subsonic vibration passed through the water and struck the amoeba’s neural structures, disrupting the signals that coordinated its movements.
The creature convulsed.
Its body contracted violently, then expanded in a series of uncontrolled pulses. Its enormous mass struck the ceiling and slid sideways, no longer capable of directing its own movement.
For a moment, the amoeba was helpless.
The Knights began converging on its position.
Paul and Arkadiusz moved toward the reactor chamber. Mordecai followed, his weapon raised. Noelani kept her distance from the creature, watching its every movement.
The nano construct returned from the crossroads, ready to assist in finishing the last invertebrate.
They believed the battle was almost over.
They believed the Radboleth was dead.
They believed the worst was behind them.
Then the reactor screamed.
The first warning was a vibration that passed through the floor and into their bodies.
The second was a series of metallic impacts, deep and thunderous, as enormous mechanisms engaged somewhere inside the facility.
Noelani turned toward the fusion core.
A line of red light appeared along the chamber’s upper wall.
Then another.
Then a third.
The Radboleth’s fallen body lay motionless in the corner.
But its tentacles were moving.
Not the severed, twitching remnants scattered across the floor. The deeper ones—the ones that had remained hidden beneath the creature’s body, still connected to the core through the mass of conduits and damaged machinery—had begun to tighten.
The creature had never relinquished its grip on the reactor.
Its apparent death had changed nothing.
A hidden sequence of controls activated.
REACTOR-SPILL BULKHEAD CASCADE INITIATED.
The warning appeared across every surviving display.
CONTAINMENT FAILURE.
EMERGENCY FLOODING PROTOCOL ACTIVE.
SECTOR 7G: CRITICAL.
The ceiling hatches opened.
The bulkheads began to cycle.
A tremendous surge of liquid exploded through the chamber as the damaged reactor cooling system discharged its radioactive contents into the facility. The fluid was thick, luminous, and foul with dissolved metals, irradiated particulates, and the chemical residue of a filtration system pushed beyond its limits.
The water struck the Knights like a physical wall.
Noelani was thrown off her feet.
Garet tumbled backward, colliding with a support column. Vulgaris disappeared beneath the surge, his damaged suit scraping along the floor.
The nano construct was swept across the chamber, its synthetic body tumbling end over end before it caught itself against a structural brace.
Paul remained upright only long enough to grab a handhold.
Arkadiusz slammed into the wall.
Mordecai was caught in the center of the flood.
The great ape struck the floor hard enough to shatter the remaining lights on his suit’s chest panel. The impact tore through the damaged seal along his side. Water rushed into the armor, filling the space around his body.
His helmet alarms erupted.
PRESSURE SEAL FAILURE.
OXYGEN SYSTEM FAILURE.
INTERNAL FLOODING.
Mordecai tried to move.
His arms responded sluggishly. His legs felt impossibly heavy. The suit’s internal pressure had collapsed, and the rushing water was already interfering with his ability to control his movements.
He could hold his breath.
He could survive without the suit’s oxygen supply for a time.
But the decompression had done more than flood his armor. The impact had injured him, and the damaged systems offered no protection against the radioactive soup surrounding him.
His time was running out.
He had to reach the surface.
Now.
The Radboleth rose.
Its true body had never been the inert mass lying in the corner. That had been a shed portion of its flesh, a illusory decoy left behind while the real creature remained concealed in the complex’s machinery and conduits.
The Knights had mistaken the remains of its outer body for the death of the predator itself.
Now the real Radboleth emerged from the flooded shadows.
It was larger than they had realized. Its tentacles stretched through the chamber, some still hooked deep into the damaged reactor assembly. Others coiled around the walls and ceiling, giving the creature a network of living anchors from which to launch its attacks.
Its body glistened beneath the emergency lighting.
Its mouth opened.
The creature had been waiting for this moment.
The reactor-spill cascade had done exactly what it was intended to do: overwhelm the Knights, compromise their suits, and turn the chamber into an environment where their every movement could become fatal.
The Radboleth attacked Noelani.
A tentacle struck her across the chest, throwing her into a heap of debris. Another swept across the floor, catching her leg and dragging her toward the creature.
She fought to free herself.
The suit’s warnings flashed across her visor.
RADIATION SHIELDING FAILURE.
EXTERNAL CONTAMINATION CRITICAL.
MOBILITY SYSTEM DEGRADED.
She forced herself upright.
The Radboleth lunged.
Noelani brought up her Mark V blaster and fired directly into its head.
The shot struck the temple.
The creature screamed.
Its tentacles lashed wildly, tearing fragments from the wall and smashing a section of overhead piping. A cloud of radioactive vapor spilled into the water.
Garet, still prone, raised his weapon and fired.
The shot struck the Radboleth’s flank.
Vulgaris struggled to his feet and brought his Mark VII to bear, but his first shot went wide. His vision was blurred, his suit was failing, and the electricity that had coursed through his body had left him disoriented.
He braced himself against the wall.
The Radboleth turned toward Noelani again.
She watched it approach.
The creature’s eyes reflected her own image back at her, distorted and pale. For an instant, she felt the old fear rising—the certainty that this thing had been watching them from the beginning, learning them, understanding them, arranging their deaths with the patience of a machine.
She let the feeling pass.
She focused on what she could see.
The creature was wounded.
Its tentacles were moving more slowly now. Its body was no longer holding its shape as easily. The earlier attacks had damaged it, and the reactor-spill cascade had forced it to expose more of its true form.
It could be killed.
Noelani raised her blaster again.
She fired.
The shot struck the Radboleth’s head.
Garet fired from the floor.
Another impact tore through the creature’s side.
The nano construct surged back into the chamber, having freed itself from the debris. Its sharklike body cut through the water with powerful sweeps of its tail, and it struck the Radboleth’s exposed flank.
The creature recoiled.
Paul Best emerged from the turbulence, his weapons still functioning. He extended one hand.
A bolt of magical force streaked across the chamber and struck the Radboleth.
Then another.
Then another.
Each impact drove the creature backward, forcing it to release its grip on the reactor conduits.
The tentacles came free.
The fusion core’s light flickered.
For the first time since the battle began, the reactor’s containment systems registered a change.
The Radboleth had lost control of the core.
But it was not dead.
Not yet.
Vulgaris found his footing.
He raised the Mark VII and fired again.
This time the shot struck the Radboleth squarely in the chest. The creature’s body convulsed, and a spray of dark fluid burst from the wound.
Vulgaris fired once more.
The second shot tore through the same region, opening a ragged cavity in the creature’s flesh.
The Radboleth turned toward him, but Noelani was already moving.
She crossed the chamber with her ColdSteel Gunstock War Club raised in both hands.
The creature’s tentacles lashed toward her.
She ducked beneath the first, twisted around the second, and struck the third with the heavy weapon. The impact tore the appendage away from the creature’s body.
She did not stop.
She struck the Radboleth across the temple.
The blow drove its head sideways.
She struck again.
The creature tried to retreat, but the nano construct had moved into position behind it. Garet continued to attack from the floor, sending nanites into the creature’s damaged tissues. Paul maintained his assault, forcing the Radboleth to divide its attention between the Knights.
For a few precious seconds, they fought as one.
No one was isolated.
No one was left to face the monster alone.
The Radboleth lashed out in desperation.
One tentacle caught Noelani across the shoulder, sending her spinning into the water. Another struck Garet’s suit and tore away a strip of damaged armor. A third swept across the floor, forcing Vulgaris to leap backward.
The Knights’ suits were barely holding together.
Their warning systems had become a continuous chorus of alarms. Every movement threatened to worsen an existing breach. The radioactive fluid clung to their armor, and the pressure of the flooded chamber made even simple actions exhausting.
They had no time left for a prolonged fight.
Noelani rose.
The Radboleth turned toward her.
She saw the movement coming.
She gathered herself, focused her attention, and surged forward with a burst of speed that seemed to carry her through the water faster than the creature could react.
Her war club struck the Radboleth’s temple.
The impact was tremendous.
The creature staggered.
Noelani struck again.
The weapon connected with the same damaged region, crushing tissue and fracturing the creature’s skull-like structure beneath its skin.
The Radboleth screamed.
Its tentacles thrashed wildly, smashing into the walls and tearing apart the remaining conduits. The fusion core pulsed with a violent green flare as the creature’s grip on the reactor finally broke.
Noelani stepped forward.
She raised the ColdSteel Gunstock War Club one final time.
And brought it down.
The blow landed squarely against the Radboleth’s temple.
The creature collapsed.
Its tentacles fell limp, one after another, spreading across the floor like severed cables. Its enormous mouth hung open, its teeth exposed in a final, grotesque grin.
The body convulsed once.
Then again.
Then it stopped.
The Radboleth was dead.
Not wounded.
Not hiding.
Not waiting to rise again from some forgotten corner of the complex.
Dead.
Its body lay in a pulpy, ruined mass beneath the reactor’s fading light.
Noelani stood over it, her weapon hanging at her side.
For several seconds, the only sound was the frantic hiss of the Knights’ damaged suits.
Then Paul Best spoke.
“Please tell me that one’s actually dead.”
Garet looked at the remains.
He examined the creature’s motionless body, then the conduits from which its tentacles had been torn free.
“Yes,” he said quietly. “This time, I’m certain.”
Noelani lowered her head.
They had done it.
The nightmare that had haunted Melkath was finally over.
The immediate danger had passed, but the reactor continued to fail.
Paul and Arkadiusz moved toward the control systems while Garet and Vulgaris checked the remaining equipment. The nano construct remained near the Radboleth’s body, its sharklike tail moving slowly through the water as it watched for any sign of renewed activity.
Mordecai was in no condition to help.
They found him near the edge of the chamber, struggling to keep his head above the flooded suit’s interior waterline. His breathing was ragged, and his movements had become slow and uncoordinated.
Paul knelt beside him.
“Mordecai! Stay with us.”
The great ape managed a weak gesture.
“Not… planning… on leaving.”
“Good. Because I am not explaining to Thisshish that we lost you after everything else.”
Mordecai tried to laugh.
It came out as a cough.
Garet examined the damaged suit and shook his head. The repair nanites had sealed the most serious ruptures, but the internal systems were badly compromised. They needed to get Mordecai out of the radioactive water before the damage became irreversible.
“Surface,” Garet said. “Now.”
Paul and Arkadiusz helped lift Mordecai. Vulgaris supported his other side, moving carefully to avoid worsening his injuries.
Noelani remained behind for a moment.
She looked at the Radboleth’s body.
The creature had spent its final moments trying to kill her. Even now, surrounded by the wreckage of the reactor chamber, she could feel the weight of its attention—as though the monster had left something behind in the water, a residue of malice that would take years to wash away.
She tightened her grip on the war club.
Then she turned and followed the others.
The final key was lying on the floor beside the reactor’s central support structure.
Arkadiusz spotted the skeleton first.
It had been trapped beneath a fallen maintenance panel, its bones bleached almost white by the irradiated water. A cracked identification badge remained attached to the remnants of its uniform.
The name was still legible.
DR. ELIAS VOSS — SENIOR REACTOR CONTAINMENT ENGINEER.
The body lay beside a small, shielded case.
Inside was the second authorization key.
Paul stared at it.
“You have got to be kidding me.”
He lifted the key from its case.
“Of course. The one thing we needed to find was sitting beside the corpse of the man who designed the system.”
“Perhaps he was trying to save the reactor,” Arkadiusz said.
“Perhaps he was trying to save himself.”
No one answered.
They had seen enough skeletons in Melkath to know that the Ancients’ final moments were rarely dignified. Dr. Voss had died beneath a collapsed panel, surrounded by the machinery he had spent his life maintaining. Whatever he had tried to do, he had failed to escape.
The Knights could not afford to dwell on it.
They had a reactor to save.
They returned to the control room as quickly as their damaged suits allowed.
The countdown was still running.
Its numbers had dwindled to a few remaining minutes, and the warning lights had turned a deep, pulsing red. The console displayed a cascade of failures across the facility’s control systems. Containment stabilizers were operating below safe thresholds. Coolant circulation had been interrupted. Several bulkheads remained sealed.
Paul inserted the first authorization key.
Arkadiusz inserted the second.
They looked at each other.
“Ready?” Paul asked.
Arkadiusz nodded.
They turned the keys simultaneously.
For a fraction of a second, nothing happened.
Then the console chimed.
DUAL AUTHORIZATION ACCEPTED.
The blast-door controls unlocked.
A second message appeared.
CONTAINMENT PROTOCOL RESTORED.
The countdown stopped.
Paul leaned closer to the screen.
The warning indicators began to change.
Red became amber.
Amber became green.
Across the facility, emergency pumps activated. The filtration system, previously overwhelmed by the reactor’s radioactive discharge, began drawing contaminated water through its restored circulation network. Damaged valves closed. Cooling lines reopened. Containment systems returned to their programmed operating states.
The fusion core’s glow steadied.
The violent fluctuations subsided.
For the first time since the Radboleth had begun its assault, the reactor’s output stabilized.
The console displayed a final message.
FUSION CORE: STABLE.
CONTAINMENT: SECURE.
POWER GENERATION: AVAILABLE.
Paul stared at the screen.
Then he sat down on the nearest surviving chair.
“I am never going underwater again.”
Arkadiusz laughed.
It was an exhausted, disbelieving sound, the kind of laughter that comes when the body has finally realized it is no longer required to fight for its life every second.
Garet leaned against the console.
Vulgaris removed one hand from his damaged suit and flexed his fingers.
Noelani closed her eyes.
The reactor was alive.
Melkath would have power.
And the Radboleth was dead.
The journey back to the surface was slow and painful.
Mordecai could barely walk. His damaged suit had been stabilized enough to keep him alive, but every movement caused him visible discomfort. The others supported him through the flooded corridors, past the ruined bulkheads and the remains of the creatures that had tried to stop them.
The filtration system continued to operate behind them.
Its pumps hummed steadily, drawing the radioactive sludge away from the reactor chambers and into the ancient treatment infrastructure. The process would take time, perhaps far longer than any of them could afford to spend in Melkath.
But it had begun.
They passed the auxiliary control room where they had found the first key. They crossed the chamber where the skeleton had drifted from the cistern. They followed the route that had brought them into the complex, moving past the twisted bulkhead doors and the dark openings where the Radboleth had once waited.
At last, they reached the shaft leading upward.
The climb seemed endless.
Mordecai stumbled repeatedly, his strength failing. Paul and Vulgaris took most of his weight while Arkadiusz moved ahead to check the route. Garet remained close behind, monitoring the damaged suit and watching for any sign that Mordecai’s condition was worsening.
Noelani brought up the rear.
She kept looking back.
Not because she expected the Radboleth to return.
Because some part of her still could not believe that it was gone.
The last stretch brought them to the cracked dome at the bottom of the drained crater-lake. Pale daylight filtered through the fractured surface above, illuminating the water with a soft, almost gentle glow.
They emerged into open air.
The radioactive wind swept across the crater, carrying the smell of scorched earth and ancient minerals. Far above, the sky stretched wide and colorless over the ruins of Melkath.
They laid Mordecai down on a relatively clean patch of ground.
Garet and Paul worked together to remove the damaged Depthstrider suit. The others followed, releasing the seals and stepping out of the battered armor one by one.
For a moment, no one spoke.
They stood at the rim of the cracked dome, exhausted, bruised, and alive.
Mordecai opened his eyes.
“Did we get it?”
Noelani knelt beside him.
“Yes.”
“The creature?”
“Yes.”
“The reactor?”
“Yes, Mordecai. We got the reactor.”
He closed his eyes again.
“Good.”
Then, after a pause, he added, “I hate this place.”
Paul laughed.
This time, the others joined him.
They embraced one another there at the edge of the crater, beneath the open sky. No ceremony. No speeches. Just the simple, overwhelming relief of being alive when every rational calculation had suggested they should be dead.
The Gamma Knights had survived another brush with annihilation.
But this time, they had done more than survive.
They had saved Melkath.
The journey to the Sleeth camp took longer than expected.
Mordecai needed rest, and the others were in little better condition. Their armor had been damaged, their equipment contaminated, and their bodies pushed beyond the limits of endurance. They moved slowly across the broken ground surrounding the crater-lake, stopping whenever Mordecai needed to recover his strength.
The land around Melkath looked unchanged.
The shattered dome still lay beneath the cracked earth. The ancient structures still stood in their grim silence. The wasteland stretched toward the horizon, indifferent to the catastrophe that had nearly unfolded beneath it.
Yet something had changed.
The power plant was functioning again.
The Radboleth no longer haunted the flooded depths.
The filtration system was working, and the facility’s containment mechanisms had returned to life.
For the first time in a long while, Melkath possessed the possibility of a future.
When the Knights finally reached the Sleeth camp, they saw movement among the shelters.
Someone had spotted them.
A figure broke away from the gathering crowd, then another. Within moments, the camp was alive with activity as Sleeth emerged from their dwellings and hurried toward the approaching figures.
Thisshish stood at the front of the gathering.
For a moment, the ancient reptilian watched them in silence.
His disbelief eventually waned, but for a moment he stood there, blinking.
The reaction spread through the camp like fire through dry grass.
A cheer erupted.
It rose from dozens of throats, growing louder as the Sleeth realized that the Knights had returned—not as desperate survivors fleeing a failed mission, but as the people who had accomplished what they had set out to do.
They had gone into the depths of Melkath.
They had faced the Radboleth.
They had restored the reactor.
And they had come back alive.
Thisshish approached them, his expression grave but his eyes bright with unmistakable relief.
“You have returned,” he said.
Paul smiled wearily.
“We did.”
“And the creature?”
“Dead,” Noelani answered.
The word carried across the gathering.
For a moment, the Sleeth seemed unable to believe it. Then the cheering grew louder, and the Knights found themselves surrounded by a jubilant crowd.
Hands reached out to clasp their arms and shoulders. Voices called their names. Someone brought water. Someone else produced food. A group of young Sleeth began shouting a victory chant that spread through the camp until it became impossible to hear anything else.
Mordecai was helped to a place of rest, where healers immediately began tending to his injuries. Garet sat down heavily beside him, too exhausted to do anything more than accept a cup of water. Vulgaris leaned against a shelter post and watched the celebration with a quiet, disbelieving smile.
Arkadiusz stood among the Sleeth, allowing himself to be congratulated with the awkwardness of a man who had never quite learned what to do with gratitude.
Paul Best looked toward the distant crater.
For the first time since entering Melkath, the green glow was no longer the most important thing on the horizon.
It was merely a light.
A light that could be controlled, maintained, and perhaps one day used to rebuild something worth preserving.
As the celebration continued, Thisshish approached Noelani and the others.
His people had begun preparing a feast. The camp’s fires were burning brightly, and the smell of cooked food drifted through the gathering. Laughter rose from groups of Sleeth who had spent too long living under the shadow of the Radboleth’s imposing will.
Thisshish waited until the Knights had gathered around him.
“You have done something extraordinary,” he said. “You entered a place that had become a tomb. You faced a creature that had brought terror to Melkath. And you restored the power that our people feared was lost forever.”
He paused.
“Waldis must hear of this.”
Waldis had sent them into the heart of Melkath with a purpose, and now that purpose had been fulfilled. But their mission had revealed more than a reactor in danger. It had exposed the terrible extent of the Radboleth’s influence, the fragility of the Ancients’ surviving infrastructure, and the degree to which the world they inhabited remained vulnerable to the failures of a civilization long dead.
Thisshish continued.
“I will make certain that Waldis receives the news quickly. He will wish to speak with you himself.”
“Where?” Arkadiusz asked.
Thisshish inclined his head.
“In the Garden of Steel.”
The words settled over the group.
The Garden of Steel.
A destination that promised answers—and perhaps new questions.
Noelani looked toward the fires, where the Sleeth were celebrating the return of their future.
She thought of the Radboleth’s final moments. Of the reactor’s warning lights. Of Mordecai struggling to breathe in his ruined suit. Of the moment the control console had finally turned green.
They had won.
For now, that was enough.
The Gamma Knights joined the celebration.
Above them, the stars emerged one by one as the wall turrets hummed back to life, their targeting systems sweeping the darkness with renewed vigilance.
And far beneath the cracked earth of Melkath, the fusion core continued to burn—steady, contained, and alive.
For the first time in a very long while, the future was not counting down.
It was beginning.
