The creature appeared beside Doc before his next breath.

Doc brought the shield up on pure reflex.

The impact drove him back three steps. Ice claws scraped against reinforced wood with a sound like breaking glass. Frost spread across the shield's surface in jagged patterns.

Doc's arm screamed protest. The force behind the blow was immense—far beyond what the creature had been capable of in the clearing.

He recovered fast. The suit's servos compensated, stabilizing his stance before the follow-up came.

The creature lunged again.

Doc sidestepped, blade already in hand.

He drove it forward—the same upward strike that had wounded it before. He aimed for the gap beneath the ribs.

The blade bit deep.

But Doc noticed something was wrong.

The resistance was off.

The creature in front of him shattered like glass.

Ice fragments exploded outward in a violent burst of steam. Superheated vapor erupted where the plasma blade met frozen matter, filling the space between them with dense, roiling fog.

Doc stopped. Raised his shield. Visibility dropped to nothing in seconds.

"That wasn't it," Doc said quietly.

"Confirmed," Lux replied. "Thermal signature dissipated on impact. Analysis indicates deliberate construct—a facsimile composed entirely of crystallized water and ambient mana. Structural cohesion maintained through continuous energy input until destruction."

Doc turned slowly, scanning the fog. "In simple terms?"

"The creature created a functional ice copy of itself using magic."

Doc sighed. "Great. Not only can it throw huge chunks of ice, but it can also create decoys of itself. Like some kind of ninja."

"Incorrect," Lux said. "What this entity demonstrates is far more advanced than historical stealth operatives from Federation records. The mana manipulation required to maintain structural integrity, locomotive function, and threat projection in a non-organic duplicate exceeds—"

"Lux. Now is not the time." Doc kept his blade up, eyes tracking movement through the steam. "Scan the area. Tell me where the creature is."

The fog shifted. Something moved in the white.

Doc's helmet display painted thermal shadows—indistinct shapes flickering at the edge of sensor range.

Three.

No—four.

"Multiple signatures detected," Lux reported. "Mana concentration consistent across all contacts. Unable to differentiate primary target from constructed duplicates at current range."

Doc adjusted his grip on the shield.

The steam began to thin at the edges, drifting apart in the cold air.

Through the haze, Doc caught glimpses—a silhouette here, movement there. Each one the same height and build.

Doc let out a slow breath

He looked down at Fish.

"Can you find the real one?"

Fish gave a huff—short, decisive.

"Affirmative," Lux translated. "Fish confirms ability to distinguish primary target from duplicates through non-visual sensory methods."

Doc nodded. "Good. Focus on finding it. I'll handle these."

Fish phased away, her form dissolving into violet tracings that scattered into the fog.

The steam fog cleared completely.

The fog thinned, and four identical figures resolved out of the white.

They moved as one.

Doc activated H.O.T. Protocol.

The world slowed and his perception sharpened. The first duplicate lunged from the left.

Doc sidestepped, bringing his blade up in a clean arc. The plasma cut through the construct's torso. It burst into steam, ice fragments scattering across the ground.

The second came from the right.

Doc turned, shield raised. The impact rattled through his arm, but he held. He drove his blade forward through its center.

It came apart the same way.

The third closed from behind.

Doc twisted, letting it overshoot. His blade found its spine.

Vapor curled where it fell.

The fourth attacked before it cleared.

Doc blocked with the shield, then countered with a low strike that shattered its legs. It collapsed and exploded into frozen mist.

The fog thickened again.

Doc stood ready, scanning through the white.

New shapes formed in the steam—more duplicates.

They attacked.

Doc moved through them — block, dodge, strike. Each one fell, but another took its place immediately.

The cycle continued.

His suit compensated for the repetitive strain. His blade carved through construct after construct.

But the steam grew denser.

Visibility dropped.

Doc switched to Lux's thermal overlay, tracking energy signatures through the white. Blue-white concentrations flickered in the fog—each one identical and moving with coordinated precision.

Doc cut down another duplicate. Then another.

"Not doing too badly," Doc muttered between strikes. "As long as it doesn't change tactics—"

"Massive mana concentration detected," Lux interrupted. "Source: directly below your position. Estimated time to manifestation: two-point-three seconds."

Doc threw himself toward the wall stairs. The suit's servos fired, launching him clear. He landed on the steps with both feet, twisting to see what he'd just left behind.

The ground where he'd stood erupted.

Ice spikes—thick as Doc's arm—burst through stone and frozen earth. They pierced upward in a deadly cluster, each one sharp enough to punch through his armor.

The fog cleared.

The entire yard floor had transformed into a sheet of smooth, dark ice. Frost crawled up the walls. The air itself felt colder.

Six duplicates stood below, unmoving. Their pale eyes on Doc

Doc's breathing came harder now. The H.O.T. Protocol was burning through his reserves faster than anticipated.

He was outmatched.

The creature could create duplicates endlessly. Doc's stamina—enhanced or not—had limits.

Fish appeared beside him with a soft displacement of air.

Doc looked at her. "Did you find it?"

Fish huffed.

Doc smiled despite everything. "Take me to it."

He reached down, grabbing onto Fish's back.

She phased.

The bright one had vanished.

The creature stood on the wall and turned its head slowly, scanning the yard below. The heat signatures it had been tracking — the dense, banked warmth of the armored thing and the flickering wrongness beside it — were simply gone.

It had never lost prey before.

It waited. Patience was something it had learned from the old hunter, and it had learned it well. Prey that disappeared always reappeared. They had to. Warm things needed to move, and moving things left traces.

The yard below sat empty and cold. The ice it had pushed through the stone earlier caught the pale light, smooth and dark. Nothing moved across it.

The creature's attention swept outward — past the wall, across the open snow. Then back through the hold, down toward the dim cluster of sealed warmth still moving through the  passages. Still there. Still slow.

Not them.

The air to its left shifted.

It turned.

The bright one was already there.

The blade came in fast and the creature threw ice up on instinct. Frost erupted across its forearm and chest, hardening into a dense shell before the strike landed.

The ice held. The force distributed across it the way it always did.

The blade hurt it anyway. The same way it had in the pass — the only thing that ever had. It had grown stronger since then, consumed and learned more, and still it had no answer for why this blade reached it when nothing else could.

It stepped back.

The creature looked at the place on its chest where the blade had connected. The ice there was intact.

It looked at the blade.

Azure. Silver veins threading through it like something alive. It had felt this weapon in the pass and fled it. It thought it had grown past that encounter. Every other wound it had taken was information — something to examine and adapt to. This was not a wound.

It held still and examined the feeling, the way it examined everything — pulling it apart to find the use in it. There was nothing to find. The warmth it took from every kill was something it was built to consume. This was the opposite. Something built to consume it.

The creature had not known that was possible.

Beside the armored thing, the flickering one had reappeared, amber eyes fixed on it. Watching. Patient in the way that things were patient when they believed they were going to win.

The creature's attention moved between them.

It was stronger than both. It knew that. It had consumed an entire hold's worth of trained fighters, and nothing had been able to stop it.

And yet.

It looked at the blade again.

It did not know what to do with that.

So it did the only thing it could.

It attacked.

 Doc raised his blade to block, but the strike never landed where he expected. The creature feigned left, twisted mid-motion, and drove an ice-clawed hand toward his ribs. Doc shifted his weight back and the claws scraped across his chestplate with enough force to leave scoring marks.

Fish phased in at the creature's blind side, jaws snapping for its shoulder. The creature spun and kicked before she fully formed. The blow caught her and sent her tumbling across the wall before she caught herself.

Doc pressed forward while it was turned. His blade came in clean, targeting the shoulder joint.

The creature didn't block. It dropped low, faster than anything its size should move, and swept Doc's legs. Doc hit the stone hard. His helmet took most of the impact but his vision blurred. He rolled sideways as ice erupted from the ground where his head had been.

Doc got to his feet. The creature stood three meters away, watching him with cold, patient eyes.

Fish circled wide, violet tracings shimmering as she prepared another phase-step. The creature tracked her without turning its head.

When Fish blinked forward, the creature was already moving. It didn't counter. It created.

Ice erupted beside it in a perfect mirror image — another creature, identical in every detail. Fish's jaws closed on frozen air as the duplicate shattered. The real one drove its fist into her side. Fish hit the wall's edge and barely caught herself before falling into the yard below.

Doc charged. The creature raised both hands, and the air between them filled with birds.

Not real ones. Ice constructs shaped like the scavengers that circled the Waste — wings spread, talons extended, each one detailed enough to cast shadows. They swarmed toward Doc in a coordinated mass.

Doc cut through the first three. They shattered into frozen shards that scraped against his armor. More took their place. He shifted his stance and swept the blade in a wide arc, clearing space.

The creature was already inside his guard.

It had used the birds as cover. Doc brought his arm up to block but the creature grabbed his wrist with inhuman strength. Ice spread from its palm across Doc's suit forearm, locking his joints. The creature's other hand came up, claws extended.

Fish hit it from behind, teeth finding purchase at the base of its neck. The creature released Doc and spun, hurling Fish across the wall. She landed in a crouch, snarling.

Doc ripped his arm free, the ice coating shattering. His forearm actuators were sluggish. Frost had gotten into the servos.

Left arm efficiency at sixty-three percent, Lux confirmed.

The creature stood between them. It showed no signs of fatigue.

Doc's arm was failing and Fish was hurt. Every exchange taught the thing something new, and it forgot nothing. A long fight was one Doc would lose.

Then it came at him, fast. Doc met it, blade up, reading the strike.

The strike was a feint. The creature's hand opened and the wall itself answered.

Ice tore up from the stone beneath Doc's feet — not a spike this time but a wave, a surging mass that caught him below the chest and drove him off his footing. His bad arm couldn't brace him. The blade scraped a line of light across the ice and found nothing to bite.

Impact imminent, Lux said. Brace—

The wave slammed him into the tower wall behind him.

 Stone cracked.

Then the creature was there, both hands coming down together, and it hit him through the already-broken wall. Fish phased to him in the half-second before the stone gave. He felt her weight against his side as the wall came apart.

 Then there was only stone and cold and the drop.

Somewhere above them, the fight was still going.

Calen could just catch it through the rock — faint sounds carrying down from the upper levels, too muffled to make out. He couldn't tell who was winning. Only that it hadn't stopped.

"He's still at it," Mav muttered.

He had a dead man's blade now, taken off one of the clan bodies in the yard. "How long can he keep that up?"

Calen didn't answer. He didn't know.

They moved deeper into the lower passages. The torches had burned out down here, and the only light was the faint glow off Calen's skin where his veins caught the dark. He kept one hand on the wall.

"Your friend," Mav said. "The one in the armor. He's going to die up there."

"He's not."

"You saw that thing. You watched it tear through Bale and Kain like wet paper." Mav's voice had an edge to it. "Nobody walks away from that."

"Doc's walked away from worse."

Mav stopped. "Worse than that."

Calen kept moving. "Yeah."

He felt Mav's eyes on his back, the suspicion plain even in the dark. Calen didn't explain. He didn't have the words for what Doc was, and even if he had them, Mav wouldn't have believed it.

The passage forked. Calen reached for his Resonance Veins and pushed the sense outward.

Nothing. The dark stayed dark.

He frowned. The girls had to be down here. Doc had said as much from the yard. But his sense found nothing — no warmth, no flicker of life, just cold rock in every direction. Like the place was empty. He knew it wasn't.

He'd have to do this the slow way.

Then, from the left fork, a sound.

Calen went still. Mav raised the blade.

A shape came around the corner — and Calen had his knife up before he saw the face.

Cassira.

She stopped dead. Behind her, Mira, and behind Mira, a lean man Calen didn't know, hands held awkwardly in front of him.

For a heartbeat nobody moved.

"Calen?" Cassira's voice cracked on it.

"It's me." He lowered the knife. "It's me. We came for you."

Then Mav stepped into the faint light, and the stranger's whole posture changed.

"Mav." Disbelief, plain in his voice. "You're alive. Where's Bale and Kain?"

"Dead." Mav said it flat. "That thing upstairs came down on us in the pass. Tore them apart. I'm the only one who walked out."

 The man went quiet. Whatever he'd expected, it wasn't that.

"The tail you sent us after," Mav went on. "It was the kid here" He tipped his head at Calen. "Had him dead to rights in the pass. Then that thing came out of the trees and went through Bale and Kain before either of them got a swing off."

He stopped. For a moment he just stared at nothing, back in it.

"It would've taken me too. But the armored guy found us first. Pulled the kid out, kept me alive." Mav's jaw worked. "Now he's upstairs fighting that thing alone, and we're down here. That's the whole of it."

"The armored guy." Cassira had gone very still. She looked at Calen. "Doc."

"He's holding it off." Calen met her eyes. "He told us to find you and get you out. That's what we're doing."

Something moved in Cassira's face — relief, and under it something she didn't let show all the way. Calen could see what holding it together had cost her.

"Then we go," she said.

"Not yet." It was the stranger who spoke, eyes fixed on something past them. "My bag. The clan stripped it when they cuffed me. They threw it in there."

Calen followed his gaze. A low doorway, half-collapsed, a storeroom off the passage.

"What do you need a bag for?" Mav said.

The man lifted his cuffed wrists. "Because I can't do anything useful with these on. And neither can she." He nodded at Cassira. "There's a pick in the bag. It'll open both."

Calen looked at the doorway, then up at the ceiling, where the fight was still hammering down through the stone.

"Fast," he said.

The man moved for the storeroom without waiting on anyone's leave.

The bag was where the clan had thrown it — shoved into a corner under a broken shelf, half-buried. He dragged it out, worked the buckles open with his cuffed hands, and dug through it fast. Whatever he was looking for, he found it: a thin slip of metal that caught the faint light wrong, edges etched too fine to be a simple pick.

He set it against the lock at his own wrist. A small click, and the cuff fell open.

He caught it before it hit the floor.

Then he crossed to Cassira and Mira and did the same for theirs, quick and careful. Something changed in the air around Cassira the moment the iron came loose — a sudden drop, frost ghosting along the stone at her feet. She closed her eyes for a moment, like she'd gotten part of herself back.

The man pulled his bag over his shoulder and stood.

"That's it," he said. "We move."

---

---

The passage opened into a great hall.

Calen stopped at the threshold. Stone pillars ran the length of it in two rows, climbing into a dark he couldn't see the top of. A hearth stood cold at the far end. And between the pillars, across the whole floor, lay the dead.

Clan men, dozens of them, sprawled where they'd fallen with frost crusted wounds. Calen had seen this before. In the pass, with Bale and Kain. He knew the kind of thing that opened a man up with its hands and left him to freeze.

The creature had been here. It had done all of this.

Behind him, Mira made a small sound and looked away. Cassira had gone still, taking in the carnage. The lean man just stared in silence.

"We need to move," the man said, low. "Now. Before—"

Above them, the sound that had been carrying down through the rock all this time finally arrived.

It came through the dark of the vaulted ceiling — a tearing groan of stone — and then something fell out of the black and hit the hall floor hard enough to shake it.

Calen threw an arm out, putting himself between it and the girls.

The shape rolled, came up on one knee in a skid of broken stone. Gray armor. Blue light threading the seams. A blade still burning azure in one fist, and Fish pressed close against his side, amber eyes bright in the dark.

"Doc," Calen breathed.

Doc lifted his head, and even through the helmet Calen felt the moment he found them — all of them, alive, standing there.

Then Doc's gaze went up. To the hole in the ceiling he'd just come through.

And Calen turned to follow it.
