The Guardian's remains still smoked behind them, crystalline shards scattered like broken glass across the frozen ground. Their breaths came out in misty bursts, each inhalation colder than the last. For a long moment, nobody spoke. Even Rio, usually first with some loud complaint about loot or bruises, kept his mouth shut.
The silence wasn't peace. It was weight.
The cavern still pulsed. Not loudly, not violently, but a subtle rhythm that pressed into their bones. Each pulse made the veins along the wall throb faintly with light. Blue-white threads ran deeper into the rock, pulsing as if carrying blood instead of æsther.
[ Peggy ]
"…It's still breathing."
Her voice was small, swallowed quickly by the echo.
[ Nerim ]
"Not breathing."
"Resonating."
"We killed a construct, not the Vein itself."
[ Rio ]
"Great..."
"So what?"
"We just made it mad?"
[ Kaiden ]
"Stay sharp."
"If it's reacting, it's because it knows we're still here."
Kaiden's eyes lingered on the walls. The pulses didn't just beat at random. They beat with him. His heart pounded, and the veins shimmered in exact rhythm. He swallowed, keeping the thought locked inside. No need to give them more reasons to look at him strangely.
They pressed forward.
The Frostbridge
The tunnel opened into a wide cavern where a single frostbridge stretched across an abyss. Its span was narrow, no more than two at a time, glowing faintly from within like a rib of frozen light. Below was nothing but mist — and the faint sound of water dripping somewhere impossibly far down.
The bridge didn't sit still. Every few moments, light rippled along it like a shiver, and cracks spidered across its surface before sealing again.
[ Peggy ]
"…Nope."
"I hate it already."
[ Rio ]
"You hate everything that looks the slightest bit unsafe."
[ Peggy ]
"Unsafe?!"
"Rio, that bridge is literally falling apart while we're watching it!"
A loud crack answered her. A chunk of frost dropped into the mist. No sound of it landing ever returned.
[ Nerim ]
"She's not wrong."
"This isn't stable."
"Vein structures aren't supposed to act like this."
[ Irna ]
"Then we find a way across before it destabilizes further."
She nocked an arrow loosely, as if her bowstring itself gave her balance. Kaiden studied the span, chewing his lip. They had no other path forward. No ledge, no tunnel, no hidden switch. The Vein demanded the bridge.
[ Kaiden ]
"One at a time won't work."
"Too long."
"We cross together."
"Stay close."
"No hesitation."
They stepped onto the frostbridge.
Immediately, it lurched. The pulse ran through it, out of sync with their steps, and the entire span trembled like a plucked string. Kaiden slipped, catching himself at the last instant on Nerim's shoulder.
[ Kaiden ]
"Tch— it's alive."
The bridge thrummed beneath them. Each beat matched the same cursed rhythm Kaiden had felt in his chest.
[ Rio ]
"Not anymore."
Rio slammed his spear into the frost. Æsther flared out of him, a deep brown glow like roots digging into soil. The glow ran through the cracks in the bridge, spreading outward in jagged lines. The tremors stilled, just slightly. Their boots suddenly gripped firmer against the slick surface.
Ironroot Blessing: Anchor — Activated.
The words burned across their minds, the way all blessings announced themselves.
Peggy blinked, then stomped her boot experimentally. It clung as if nailed down.
[ Peggy ]
"Oh, bless the roots!"
"I thought I was about to kiss the abyss."
[ Rio ]
"Don't thank me yet."
"The bridge hates it."
"It's pushing back."
[ Nerim ]
"Then push harder."
"We'd rather it hates you than us."
[ Rio ]
"Easy for you to say, stoneboy."
"My stamina's bleeding faster than your legs."
A sharp tremor shook the bridge as if agreeing with him. Frost shards rained from above. One sliced Irna's sleeve open, drawing a line of blood on her arm. She didn't flinch, only tightened her grip on the bow.
[ Kaiden ]
"Save the bickering for the other side."
"Move!"
They advanced quickly, the bridge humming in rebellion with every step. Anchor held them steady, but Kaiden felt the Vein retaliating. The cracks widened faster now, racing ahead like a trap priming itself. He yanked a Frostvein shard from his satchel, pressed it to the bridge — and light flared. The fissures sealed just enough for the party to rush over.
The shard dimmed, its glow dying in his palm. Used. Spent.
[ Kaiden ]
"Go!"
The bridge screamed beneath them — a sound of ice breaking under infinite weight — just as they lunged onto the far side. Behind them, entire sections collapsed into the mist. Anchor's glow faded from the frost, and Rio sagged against his spear, breathing hard.
[ Peggy ]
"…If you ever complain about your blessing again, I'll shove this hammer through your teeth."
[ Rio ]
"You're welcome."
The banter should have eased them. It didn't. The cavern ahead was darker, veins pulsing violet now instead of blue. Reflections shimmered faintly in the frostglass walls, waiting for eyes to linger.
The collapse of the bridge still echoed in their bones when they stepped into the next chamber. The air was different here — heavier, like breathing through damp cloth. The blue veins that had guided them shifted color, pulsing a muted violet, as though they were deeper inside some organ that didn't welcome them.
The walls weren't flat anymore. They curved inward, polished by æsther until they gleamed like frostglass mirrors. But these weren't ordinary reflections. Their torchlight bent strangely against the surface, doubling and stretching their shapes until every shadow was a stranger.
[ Peggy ]
"…I hate this more than the bridge."
Her hammer rested against her shoulder, but her eyes refused to leave the wall. Her reflection didn't move in sync with her. It lagged half a beat behind, then tilted its head just a fraction too far, like it was listening to something she couldn't hear.
[ Peggy ]
"Did—did you see that?"
[ Nerim ]
"See what?"
[ Peggy ]
"Myself."
"But not me."
[ Irna ]
"Where?"
Peggy's reflection smiled, even though her lips stayed tight. She cursed under her breath and turned her back to the wall, keeping her hammer raised now like the glass itself was an enemy.
Kaiden forced himself to keep walking, though every step felt like it echoed twice. His reflection stretched taller in the walls, face blurred. No eyes. No mouth. Just a silhouette shaped like him, its outline quivering as if it wanted to peel away from the surface.
A spike of cold ran down his spine.
[ * Kaiden * ]
"Don't look. Don't give it form."
Beside him, Nerim slowed. His gauntleted hand hovered inches from the wall, not touching but close enough for the frost to prickle his skin. His reflection loomed larger than him, armor bulked, hammer-sized pickaxe gleaming. A version of himself stronger, unflinching, unbreakable. Nerim's jaw tightened.
[ Nerim ]
"Mocking me already, huh?"
[ Irna ]
"Who?"
Nerim's reflection moved — swinging the pickaxe down — but the real Nerim hadn't moved an inch. He ripped his gaze away, spitting on the floor.
[ Nerim ]
"Nothing."
"Just keep your guard up, Irna."
Irna stayed silent for a while, eyes fixed on the next curve of the wall. Her reflection finally made her stop. Unlike the others, it wasn't distorted. It was perfect. Her face, her bow, her poise. But behind her reflection, another shadow loomed, wings unfurling, too large and too sharp to belong to her.
Her throat bobbed as she whispered:
[ Irna ]
"Not now…"
The others barely heard her, but Kaiden did. He glanced at her — saw her knuckles white on the guzheng-turned-bow — and chose silence.
Rio broke it instead.
[ Rio ]
"Ha!"
"Look at me."
He jabbed his spear toward the wall. His reflection smirked back at him, broader-shouldered, armor gleaming, aura practically radiating dominance.
[ Rio ]
"Damn, even the Vein knows I'm built different."
[ Peggy ]
"Yours didn't move?"
[ Rio ]
"Nope..."
"Just looks better than me."
"Which is saying something."
Peggy scowled.
[ Peggy ]
"Why am I the only one with a creepy grin then?!"
[ Nerim ]
"Because the Vein likes you."
[ Peggy ]
"Shut up!"
Their voices bounced through the chamber, too loud, like shouting in a cathedral. The reflections quivered at the sound, faint ripples distorting their shapes.
Kaiden slowed again. His own reflection had changed. The silhouette was gone. In its place was only a hollow, black void where he should have been. The veins in the wall pulsed more brightly around it, the glow bending inward as if feeding the emptiness.
He clenched his dagger tighter.
[ * Kaiden * ]
"…It's not a reflection. It's me. The me the Vein knows."
The walls pressed closer, narrowing into a throat of violet-lit glass. Their reflections crowded tighter, every angle showing them wrong, delayed, or too perfect. The chamber no longer felt like stone. It felt like being swallowed.
[ Irna ]
"Eyes forward."
"Don't let it in."
Her words cut through, steady as a bell-tone. The others obeyed, though Peggy's hammer still twitched at her side. Together they pressed on, their distorted selves trailing with every step until finally — the tunnel widened, opening into a chamber vast enough that even the torchlight couldn't catch its far edges.
The pulse here was thunder. The walls throbbed like a giant vein, violet light rising and falling.
And in the center, rooted into both ceiling and floor, waited something vast.
