Xavier POV
A sharp crack split the silence.
Xavier moved before he could think, jerking back as the black stone beneath his boot gave way. The surface broke like thin glass, collapsing into a spray of dark fragments and hot ash.
Heat rushed up from below.
Not lava.
Not yet.
But far too close.
He twisted, caught himself on his other foot, and skidded against the slope as the broken crust hissed into the hollow beneath.
For a second, all he heard was falling stone.
Then nothing.
No splash. No impact.
Just silence.
Xavier's smile faded.
He stared at the gap where solid ground should have been.
"…Well," he said quietly, "that seems unhelpful."
Black fog curled around his legs.
Ahead of him, Seth hadn't moved.
Of course he hadn't.
Xavier looked down again. The outer layer had only been a shell. Beneath it was a jagged drop lit by faint red veins pulsing through the rock below like the mountain had a buried heartbeat.
So the ground was lying.
'Well. That inspires confidence.'
A low crack sounded somewhere ahead. Then another, farther left.
The slope disappeared into fog until stone, shadow, and empty space all looked the same.
Xavier exhaled.
'Alright.'
'That is mildly terrible.'
"You noticed before I did," he said.
"Yes."
"No warning?"
Seth finally glanced at him. "You would have kept walking while smiling anyway."
Xavier let out a breath that almost became a laugh.
'Annoyingly fair.'
"Wow," he murmured. "You really are enjoying this."
"No. You're just easier to read than you think."
Before Xavier could answer, Seth crouched and pressed two fingers lightly against the ground near the break. Only for a moment.
Then he stood.
"The surface is layered," he said. "Thin crust over hollow stone. Some of it will hold. Some of it won't."
Xavier stared out into the ash-veiled slope. Whatever passed for a path was gone now, erased by fog and uncertainty.
Beneath it all, the mountain kept making quiet sounds.
Small cracks. Soft shifts.
The kind of noises that made instinct tighten.
"If only the mountain had the decency to let us see where it planned to kill us."
"Yes."
'So what exactly are you hiding?'
Seth bent, picked up a loose piece of black rock, and threw it into the fog.
It bounced once.
Twice.
On the third impact, the ground shattered.
The crust caved in instantly, and a chain of fractures raced outward before the whole section vanished into the dark.
Xavier's brows rose.
"Alright," he said softly. "That's worse."
Seth threw another stone further right.
That section held.
A third followed. Then a fourth.
One side collapsed.
One side barely remained.
"You can map it?" Xavier asked.
"Partly."
Xavier looked at the narrow line of intact stone Seth had found. It wasn't a path. More like a suggestion of one.
One wrong step and there would be no going back.
Ash drifted over it, blurring the edges.
His gaze slid to Seth.
There was something unpleasant about how quickly he had adapted.
No panic. No wasted movement.
Just observation. Judgment. Decision.
As if the mountain had presented a problem and Seth had accepted the conversation.
"You know," Xavier said, his smile returning faintly, "for someone who dislikes me, you're being unexpectedly useful."
"For someone in danger, you talk too much."
'What exactly did I do to deserve him?'
"That's how I cope," Xavier said.
"I know."
'Yes, definitely something.'
That landed more cleanly than Xavier wanted.
Of course Seth had noticed.
The ash shifted, thinning for a moment.
Xavier finally saw more of the slope ahead, and his stomach tightened.
It was all broken.
A field of thin volcanic crust stretched before them over hollow pockets and glowing fractures. Some sections might hold weight.
Others only looked solid.
It was less a path than a trap pretending to be one.
The fog closed again.
Xavier let out a low whistle. "Please tell me this gets better."
"It doesn't."
"Good. Honesty. Nice theme."
Seth ignored him and stepped onto the first stable point.
The crust held.
Barely.
He tested it once, then moved to the next with measured precision.
Xavier followed.
The first step felt wrong immediately.
He resisted the urge to look down.
Ahead, Seth moved through the ash like he already knew where the mountain would betray them next.
Xavier took another step.
Then another.
Behind them, the crust gave a faint groan.
He did not look back.
The fog thickened, and somewhere below the stone something shifted with a long, slow sound like breath moving through the mountain's bones.
Xavier's smile thinned.
Not gone.
Just showing effort now.
He stepped where Seth had stepped.
The crust dipped slightly beneath his boot.
He froze.
Seth stopped at once.
Neither of them spoke.
The black fog drifted around them, thick enough now that Seth looked less like a person and more like a shadow the mountain had decided not to swallow yet.
Xavier slowly shifted his weight back.
The stone steadied.
"Not there," Seth said.
Xavier let out a breath. "That would've been useful half a second earlier."
"You're still standing."
"What an inspiring standard."
Seth angled right onto a darker section veined with faint red lines.
"This way."
Xavier followed.
The path narrowed into a broken sequence of footholds separated by black ash that hid the edges too well. Heat rose in waves. Sometimes distant. Sometimes one bad step away.
Then the fog shifted.
Only for a moment.
But it was enough.
The slope ahead had split, leaving a thin spine of crust stretched over a deeper hollow.
Not a bridge.
The idea of one.
And it was already cracking.
Hairline fractures spread beneath the ash.
Xavier looked at Seth.
Seth was already looking at it.
"This is the route?" Xavier asked.
"It's the only one that doesn't collapse immediately."
"That is not reassuring."
Seth stepped onto it.
The spine groaned, but held.
He crossed the first half in four light steps and stopped near the far side.
Then he turned.
Xavier looked at the distance between them.
Not far.
Far enough.
Far enough when the ground wanted him dead.
'Well. This is unpleasantly symbolic.'
"If I die here," he murmured, "I'd like it noted that your directions were very cold."
"Then don't die there."
"That was almost encouraging."
"It wasn't."
Xavier smiled despite himself and stepped forward.
The first section held.
The second cracked beneath his boot.
The third bent.
Just slightly.
But enough.
His gaze dropped.
Too late.
A dark fracture ripped through the ash at his feet.
"Seth—"
The spine gave way.
The crust shattered beneath him, collapsing into black fragments and a rush of burning air. His stomach lurched as the world dropped open into red-lit dark.
Heat roared upward.
His hand shot out on instinct.
Nothing.
For one violent instant, Xavier was falling.
Then Seth moved.
No warning.
No buildup.
Just a sudden wrongness in the air, as if space itself had slipped.
His white eye flared with a cold, colourless gleam.
The world twisted.
Xavier felt it before he understood it—his body dragged sideways with nauseating force, like being pulled through a gap too small for flesh.
'What?'
Then stone slammed into his boots.
Solid.
Real.
He staggered onto the far side and dropped to one knee, breath punched out of him.
His mind caught up a second later.
The switch.
His head snapped up.
Where he had been falling—
Seth was now.
The broken spine beneath Seth caved further. One foot found purchase on a splinter of crust. The other slipped.
For the first time since Xavier had met him, Seth's balance broke.
Only for an instant.
But Xavier saw it.
Saw the fracture spread.
Saw him start to fall.
Xavier moved without thinking.
His hand shot forward.
"Seth!"
No perfect trick. No clever answer.
Only motion.
Only the ugly refusal to stand still while someone else took the fall meant for him.
Their hands caught.
Barely.
Xavier hit the ground hard, chest scraping against volcanic stone as his fingers locked around Seth's wrist. The force nearly dragged him over with him.
Heat surged up from the hollow below.
The remaining crust cracked again.
Xavier tightened his grip.
Seth looked up at him, expression sharp now. Not fear.
Something harder.
"Let go," Seth said.
Xavier almost laughed.
'Absolutely not.'
"What a horrible suggestion."
The stone beneath Seth broke again. His weight dropped lower.
Xavier's shoulder flared with pain. His grip slipped half an inch, then held.
"You're making this worse," Seth said.
"And yet," Xavier ground out, "you seem weirdly involved."
Another crack shot beneath Xavier's chest.
That one he felt.
Fast. Splintering. Real.
Seth's gaze flicked once—to the fracture, to Xavier's arm, to the edge dragging both of them closer.
Then back to his face.
"This," Seth said quietly, "is exactly what I meant."
Xavier smiled then.
Thin. Strained. Real enough to hurt.
"Yeah," he said. "I noticed."
For a second, neither moved.
Ash slid over their hands and sleeves.
Heat hammered upward.
Then Seth's expression changed.
A decision.
His free hand slammed into the inner wall of the collapsing hollow, fingers digging into a narrow seam.
Not enough to climb.
Enough to shift.
Enough to take some weight off Xavier's arm.
"Pull," Seth said.
Xavier did.
Pain lit through his shoulder and back as he dragged upward. Seth pushed off the seam and caught the far ledge with his other hand.
The crust split again.
This time they moved together.
Xavier hauled.
Seth drove upward.
And both of them crashed onto stable ground just as the last of the spine collapsed into the red dark below.
For several seconds, neither spoke.
Xavier stayed on one knee, breathing harder than he wanted to admit.
Seth crouched beside him, one hand braced on the stone.
Ash drifted between them.
Then Seth rose first.
Of course he did.
Xavier pushed himself upright more slowly and looked at him.
Then at Seth's white eye.
'Amazing.'
Then back again.
"So," Xavier said, quieter now, "that was your white eye."
"Yes."
Xavier stared at him.
"You took my place."
"I corrected the position."
That made something shift in Xavier's expression.
Not amusement.
Something softer.
Stranger.
"Right," he said.
Seth stepped past him, gaze already returning to the path ahead.
"The difference matters."
Xavier watched him for half a second, then followed.
The false crust thinned behind them, giving way to harsher volcanic stone split by glowing seams and narrow vents that hissed steam into the air. The ground was more stable here, but the mountain still felt alive beneath their boots.
For a while, only footsteps filled the silence.
Then Xavier said, "You really believe there's a difference."
"Yes."
Seth didn't look at him.
"If I moved because I couldn't bear to watch you fall, that would be one thing. I moved because you were in the wrong place and I could still recover from the one I took."
His voice stayed level.
"That is not the same."
"And yet you still look like it cost you."
Xavier glanced at his half-lidded white eye.
Seth was looking elsewhere.
Through the thinning ash, the volcano finally took shape.
Its base loomed ahead like a wall of shadow.
Too still.
Too large.
Xavier's smile returned, but softer now.
"You know," he said, "for someone who doesn't like me, you keep saving my life."
"For someone who keeps hearing the same answer, you ask the same question a lot."
Xavier laughed under his breath.
"There. That almost sounded like a personality."
"I'm devastated you noticed."
Xavier blinked.
Then stared.
Seth kept walking as if he had said nothing.
A grin pulled at Xavier's mouth despite everything.
'Oh, so he can do that.'
"Be funny, I mean," Xavier said.
"I wasn't."
"That makes it worse."
The path steepened as they approached the volcano's base. Jagged shelves of black rock forced them higher, weaving around glowing cracks where lava moved beneath the surface. Each breath felt sharpened by heat.
Then they reached level ground.
And stopped.
Ahead of them, the base of the volcano curved upward in a vast ring of dark stone split by glowing fissures and old scars of cooled magma. At its centre yawned an opening broad enough to swallow a building.
Heat poured from it in furnace-like breaths.
Something deep inside rumbled once.
The rock beneath their feet answered with a faint tremor.
Xavier stared at it.
"That looks unpleasant."
"It is."
"You say that like you've already decided."
"I have."
"Of course you have."
For a moment, neither moved.
The mountain breathed again.
Hot.
Dry.
Ancient.
Xavier glanced at Seth once more—at the black eye, the white one, the profile of someone who had taken his place in a fall and still insisted on calling it correction.
Then he smiled faintly.
"You know," he said, "I still think it looked the same from my side."
Seth kept his eyes on the entrance.
When he answered, his voice was quiet.
"I know."
That was all.
No correction this time.
No argument.
Just that.
For some reason, Xavier felt that more than everything else.
Then Seth stepped forward.
"Stay close," he said.
Xavier's smile sharpened. "There it is."
Seth didn't look back. "What?"
"Something honest."
The volcano rumbled again.
And this time, when they stepped into its shadow, even Xavier stopped smiling.

Seth POV
Heat rolled from it in slow, furnace-like breaths.
Seth stepped inside first.
The chamber beyond was wide enough to swallow sound. Black stone curved overhead in jagged arches, split by thin veins of molten red that pulsed faintly through the walls. Narrow vents hissed from the rock, sending steam and ash into the air in soft bursts.
Behind him, Xavier entered a second later.
Neither of them spoke.
Seth's gaze moved once across the chamber.
Then again.
The ground was wrong.
Not because it was uneven. Volcanic rock was never smooth for long. But this felt arranged. The chamber opened too neatly toward a wide basin of black crust at its centre, ringed by shelves of obsidian and old magma flow.
A place made for something.
Not comfort.
Not rest.
A boss chamber.
Seth listened.
The mountain had not gone quiet.
It had only changed its voice.
The deeper groaning of pressure still lingered far below, but here there was something else beneath it. Something slower. Lower.
A faint vibration passed under the floor.
So slight most people would never have noticed it.
Seth did.
'Not the mountain.'
"Please tell me that look means you've found a safe route," Xavier said.
"No."
"Good. Consistency matters."
Seth kept walking.
The closer they got to the basin, the clearer it became. The crust over it was darker than the rest of the chamber. Smoother too. Almost glassy in places.
Too thin.
Another vibration ran beneath it.
Longer this time.
The surface quivered once.
Then stilled.
Seth stopped.
"Move back."
Xavier glanced at him. "That tone usually means—"
The basin exploded.
Black crust burst upward in a violent spray as something enormous tore through it from below. Heat roared across the chamber, carrying shattered stone, molten fragments, and a wave of ash hot enough to sting exposed skin.
Seth moved sideways at once.
Xavier leapt back.
A vast shape surged from the basin in a twisting arc of obsidian-black scales and molten seams. Its body was long and sinuous, plated in overlapping volcanic armour with glowing red cracks running between each scale like magma trapped beneath the surface.
Its jaws opened wide enough to swallow a man whole.
Jagged black fangs lined its mouth, lit from beneath by an inner furnace glow.
Its eyes burned ember-red.
Focused.
Not wild.
The serpent rose higher, ash and heat shedding from its body, then came crashing down across the chamber with enough force to crack the stone beneath it.
Xavier slid to a stop and stared up.
"…Right," he said softly. "That's unpleasant."
Seth said nothing.
He was already watching the way it held itself.
The tension in the coils.
The angle of the head.
The gathering force beneath the scales.
'Fast.'
The serpent turned toward them.
And lowered itself to strike.
Seth shifted forward—
—and Xavier moved first.
Of course he did.
Light burst from his body in a sharp flare as three radiant doubles split from him and scattered across the chamber. They moved with him, not perfectly, but close enough that for half a second even Seth's eyes had to sort the real from the false.
The serpent lunged.
Its jaws tore through one clone.
Then another.
Both shattered into sprays of pale light.
Xavier himself was already elsewhere.
He flashed across the serpent's flank, blade arcing in a bright crescent that carved over the glowing seam between two obsidian scales.
The strike landed cleanly.
A line of light tore across the serpent's side—
and only chipped the armour.
The beast barely reacted.
Xavier did not slow.
He stepped again, another clone splitting from his movement as he drove up over a ridge of black stone. His sword flashed twice more in crossing arcs of white-gold light, each slash aimed at the molten cracks running through the serpent's body.
More sparks.
More chips.
No real damage.
The serpent turned its head toward him, ember-red eyes fixed now with something colder than instinct.
Seth watched the body.
The tension in the coils did not change.
The injury did not matter.
'Too shallow.'
'The outer shell is absorbing most of it.'
Xavier seemed to realise it at the same time.
He landed lightly on a higher shelf, smile still in place, though thinner now.
"Well," he said, "you are dramatically less fragile than I'd hoped."
The serpent answered by driving its tail into the floor.
The chamber shook.
Not a tremor.
A violent convulsion.
Stone cracked in branching lines as pressure surged beneath the surface. Molten heat flashed through the fractures—
then the floor erupted.
Jagged red ore burst upward in brutal clusters, ruby-coloured and razor-edged, spearing out from the volcanic rock in crooked pillars. Some were as tall as a man.
Others shot all the way to the ceiling.
Xavier vanished in a flash of light as one tore through the place he had just been standing.
Another exploded up beneath Seth.
He stepped off the breaking ground and landed on a narrow shelf as more crimson spikes erupted across the chamber, turning open space into a forest of blades.
The serpent ripped its tail free.
At once, magma burst from the fractured lines it had made, splashing between the ruby growths in glowing sprays.
So that was its answer.
Break the floor.
Restrict movement.
Force them upward.
Seth's eyes narrowed.
'The tail triggers it.'
'Not random.'
Across the chamber, Xavier stood balanced on the tip of one of the jagged ruby spires, coat shifting in the rising heat. Light gathered faintly around him, reflecting off the red crystal beneath his boots until he looked half-drowned in refracted fire.
The serpent rose toward him.
Fast.
Its jaws opened.
Seth's body tensed to move—
Then he stopped.
For the first time since the fight began, something about Xavier made him pause.
The light around him was wrong.
Not brighter.
Denser.
It did not spill from him the way it had before. It folded inward, pulling close to his body, his sword, even the air around him. The remaining clones did not scatter.
They held.
Still.
Perfectly still.
As if waiting.
Seth's gaze sharpened.
He had never seen that before.
'What is he doing?'
Xavier lifted his blade.
Every clone mirrored him.
The chamber seemed to hold its breath.
And then—
