The corridor stretched ahead, narrower now, walls etched with faint, pulsing runes that brightened and dimmed like slow breaths. Percia walked a half-step ahead, her eyes scanning the floor for the telltale shimmer of pressure plates she had already cataloged.
She spoke without turning.
"Where do you think your master would be?"
Fern answered immediately, as though the question had been waiting on her tongue.
"Deeper. Probably in one of the sealed vaults or the archive chambers. She always goes where the oldest magic lingers."
Percia tilted her head slightly. "And what draws her there? This dungeon functions like most of its kind—it draws inhabitants in with bait. Tailored. Personalized. What is bait to her?"
Fern didn't hesitate.
"Magical trinkets. Grimoires. Mimic chests. Anything that she hasn't seen before."
Stark nodded along, wiping dried blood from his jaw with the back of his hand. "Yeah. She sometimes just stares at some dusty old book or weird glowing orb for hours. We usually have to drag her away before something tries to eat us."
Percia blinked.
For a heartbeat the corridor blurred.
White hair catching moonlight through a cracked window. Green eyes bright with quiet, childlike wonder as slender fingers turned the pages of a crumbling tome. A soft voice murmuring, "Look at this one, Percia. The weave here… it's almost alive." Laughter—rare, gentle—when the mimic chest snapped shut on empty air instead of her hand.
The memory was uninvited, sharp as winter air.
Percia exhaled through her nose, soft and controlled.
"Very well."
She lifted her right hand, palm up. Mana gathered in delicate spirals, pale silver-blue, coiling like smoke. She murmured a phrase too quiet for human ears—old elven syllables that tasted of frost and forgotten libraries. The spell took shape slowly, adapting, feeling the dungeon's pulse like a living thing. It tasted the ambient magic, the shifting ley lines, the way the ruin itself lied and lured.
A single strand materialized in the air before them—thin as spider silk, shimmering with faint iridescence. It hung suspended, quivering, then gently tugged forward and to the left, toward a side passage Percia had marked weeks earlier but never fully explored.
"There," she said. "It will adjust as we move. The dungeon will try to mislead, but this thread remembers the signature it's chasing. Stay close. If it flickers or changes color, stop immediately."
Fern's eyes followed the strand with something close to reverence. "You made it… adapt to the dungeon?"
"It's more polite to say I persuaded it," Percia replied dryly. "Now move."
She started forward again, the strand leading like a will-o'-the-wisp. Fern and Stark fell in behind her—Fern silent and focused, staff held ready once more; Stark gripping his chipped axe with renewed determination, though he winced when he flexed his newly healed shoulder.
The thread pulsed softly, steady.
Percia kept her expression cool, gaze fixed ahead.
But every few steps, when the corridor bent and the light dimmed, she felt the ghost of white hair flicker at the edge of her vision.
She told herself it was only the dungeon playing tricks.
─────────────────────────────────────────────────
The corridor had grown unnaturally quiet.
No skittering claws. No distant groans of shifting stone. No sudden flare of trap runes. The dungeon seemed to have... noticed. As though the ancient mechanism of the place had taken one look at the elven mage walking its halls and decided provocation was unwise. The strand of tracking mana floated ahead like a calm river current, untroubled, leading them deeper without resistance.
Fern walked close behind Percia, violet eyes flicking repeatedly to the other elf's back. She didn't speak at first—Fern rarely wasted words—but the silence pressed against her curiosity until it cracked.
"Your mana…" Fern said softly, almost to herself. "It's like the ocean. Deep. No bottom I can feel. Even when you cast that tracking spell, it barely rippled."
Stark, a step behind, gave a low hum of agreement. His gaze had been tracing Percia's movements for the last several minutes—the precise way she placed each foot, the subtle shift of balance that spoke of someone who had once trained with blades as well as spells. Not the loose, spell-heavy gait of most mages. Something older. Sharper. Swordsmanship, maybe. The kind that came before magic became easier.
Without turning, she spoke, voice cool and edged with faint irritation.
"Stop probing at me. Both of you. It's rude."
Fern's cheeks flushed pink instantly. She looked down at her boots, fingers tightening around her staff.
Stark rubbed the back of his neck, ears going red. "Sorry. Didn't mean to—"
Percia ignored them and continued. They followed in chastened silence.
A few turns later, the thread thinned to near-transparency, quivering as it pressed itself flat against the surface of a heavy stone door. Runes along the frame glowed faintly, then dimmed, as though acknowledging defeat. Percia laid her palm against the door. No wards triggered. No resistance. It swung inward on silent hinges.
Inside: a circular chamber, shelves of dust-covered tomes lining the walls, faint motes of light drifting like fireflies. And in the center—
A mimic chest. Large. Ornately carved to look like an ancient coffer. Its lid clamped shut around something—or someone—stuck halfway in, legs kicking faintly, muffled curses drifting from within.
"Frieren-sama!"
Fern bolted forwards before anyone could react, staff clattering against stone as she dropped to her knees beside the chest.
Stark let out a short, incredulous chuckle under his breath. "She really did get herself stuck in a mimic. Classic."
Percia remained in the doorway.
She drew her cloak closer around herself, fingers curling into the fabric. The dungeon's chill suddenly felt sharper against her skin. She wanted this over. Wanted the humans gone. Wanted to return to the quiet corners she had claimed, to trace glyphs undisturbed, to let centuries pass in peaceful solitude again.
Fern was already prying at the mimic's edges, murmuring apologies and reassurances. Stark stepped up to help, wedging his chipped axe into the gap between lid and base, muscles straining.
With a splintering crack, the chest yielded.
The figure tumbled out in a heap of white hair and rumpled robes, coughing, brushing dust from her sleeves with an air of mild annoyance rather than alarm.
Fern dropped to her side immediately, hands fluttering. "Frieren-sama—are you hurt? I'm so sorry we took so long—"
The small elf sat up, blinking slowly at her student. Green eyes, calm and faintly bemused, the same eyes that had once looked up at her with childlike wonder.
Even from the back—slender shoulders, the familiar fall of snow-white hair, the way she tilted her head when mildly inconvenienced—there was no mistaking it. Percia's jaw clenched.
Frieren waved off Fern when she tried to wipe off the monster spit. She instead turned, her gaze drifting past Fern, past Stark, and landing—slowly, inevitably—on the figure in the doorway.
A long beat of silence.
Frieren blinked once.
Then, in that same placid, unchanging tone she had always used:
"…Percia?"
The word hung in the dusty air.
Fern looked between them, confused. Stark's chuckle died in his throat.
Percia did not move.
She felt the old, familiar ache bloom somewhere behind her ribs—not sharp, not new, just… there. The same ache that had settled in centuries ago when white hair had walked away down a sunlit path and never quite come back the same way.
She told herself to turn. To leave. To let the dungeon swallow her again.
Frieren tilted her head, studying her with those unchanging green eyes.
"You're shorter than I remember," she said simply.
Percia closed her eyes and huffed, "You've just grown taller."
