The tunnel entrance behind the Academy's north wing yawned open like a stone throat — dark, damp, ringed with iron runes bolted in place so long ago their edges were half-swallowed by moss. Water dripped from the rune posts, carving tiny grooves into the old stone step. A single rune-lamp above the arch flickered like a tired eye, casting shadows that stretched and shivered when the wind gusted through.
A battered post stood half-swallowed by trailing ivy: "Ironroot Vein: Training Access Only."
Kaiden lingered near the back of the group, hugging his elbows. He watched the flickering rune-lamp reflect off the others' faces — excited, worried, too bright for the cold shade around them. Peggy had one boot braced on Rio's pack to stop him from bouncing out of line every five seconds. Nerim was whispering to himself, fingers drumming on the cloth bag of borrowed chalk like it might jump out and run away.
Irna just tugged her sleeves over her hands, peeking at the dark like it might peek back.
A boy stood by the mouth of the tunnel — a sixth-year, judging by the green strip stitched to his collar. He had spiky brown hair that stuck up every which way and a grin too big for his face, like he'd been waiting all morning to scare sprouts half to death.
[ ??? ]
"Alright, sprouts!"
"Roll call!"
He thumped the old rune-post for emphasis, sending a shiver of light down the moss. Kaiden noticed the half-faded scars along the boy's jaw — thin, like claw scratches that had never healed right.
[ ??? ]
"Name's Jaren."
"Jaren Stryde."
"Sixth-year."
"Ironroot born and trained, but don't think I'm your babysitter."
"Today I'm your Vein Buddy — lucky you."
Rio leaned over, hissing in Kaiden's ear.
[ Rio (whispers) ]
"Vein Buddy?"
"That sounds like something you catch from bad river water."
Peggy's elbow found Rio's ribs before Kaiden could laugh.
[ Peggy (deadpan) ]
"Better than being a lost root."
[ Nerim (mumbling) ]
"Lost root, lost boot, lost bones…"
Jaren twirled the battered iron lantern on its hook and pointed at the runes etched around the arch. His shadow swung behind him, long and thin like a branch dancing in a storm wind.
[ Jaren ]
"Listen up, short roots."
"This is a shallow Vein — old branch, no live ore flow, no deep creatures."
"But it's still a Vein, still a dungeon."
"Treat it like you'd treat a bear you think is asleep."
"One wrong poke and it'll show you its teeth."
He crouched to their level — so close Kaiden could see the flecks of iron dust trapped under his nails.
[ Jaren ]
"First rule: the Vein remembers you."
"Second rule: you remember it back."
"Third rule: don't wander off."
"You get lost down there, it won't be me dragging your scrawny hide back."
Rio's hand shot up so fast he nearly poked Jaren in the eye.
[ Rio ]
"Is it true there's a troll down there?"
"Or ghosts?"
"Or — wait — a ghost troll?!"
"Or is it..."
"Troll ghost???"
Nerim was indifferent. Irna squeaked. Peggy just sighed, eyes half-lidded.
Jaren barked a laugh that bounced down the corridor, echoing back in strange whispers.
[ Jaren ]
"Troll ghost, huh?"
"Spirits, I hope so."
"I'd put that on my badge — 'Jaren Stryde, Sixth-Year Vein Buddy: Sole Survivor of the Ghost Troll Incident.'"
Rio puffed out his cheeks, trying to look brave. Kaiden almost expected him to swing his pack like a club.
[ Peggy ]
"Calm your nerves, Rio."
"You'd faint before you got a punch in."
[ Rio (pouting) ]
"Would not."
Peggy flicked his forehead so hard he yelped. Irna giggled behind her sleeves. Even Nerim cracked a grin.
Jaren hoisted his lantern high, the iron frame creaking on its chain. Light flickered over the old rune-marks, chasing away the shadows just enough to make them deeper again.
[ Jaren ]
"Stay close."
"Touch the wall if you lose your head."
"Roots in, roots out — that's how we grow."
◈◈◈
They stepped inside.
Cold air wrapped around Kaiden's neck like a damp scarf. The tunnel walls wept faint rivulets that carved tiny channels into the stone, trickling into puddles that smelled faintly of rust and moss. Their boots crunched on gravel and the squeak of old chalk from past classes — tiny suns, runic eyes, a crude stick-figure troll with horns bigger than its legs.
Rio poked it with his chalk stub.
[ Rio ]
"That's gonna be my mark."
[ Peggy (flat) ]
"It's a line."
"Draw a line."
[ Rio (sticks tongue out) ]
"It's my line."
Nerim pressed his ear to the wall, muttering about fault lines and ore pockets like they were secrets the Vein only told him.
Kaiden ran his fingertips along the roots poking through the ceiling — white, hair-thin threads of old merantis. They pulsed when Jaren's lantern swung near, like they were breathing.
[ * Kaiden * ]
"Alive."
"Remember me."
Irna caught his arm with her sleeve, voice soft as water dripping from the ceiling.
[ Irna ]
"Feels like it's watching."
Kaiden nodded.
[ Kaiden ]
"That's good."
"Means it knows we're here."
Jaren stopped them at a fork where the tunnel split around an ancient support pillar. He slapped his lantern onto an iron hook and unrolled a cloth of rune chalks — five colors, worn to nubs.
[ Jaren ]
"Here's the big secret, sprouts: Dungeoneering ain't just about swinging picks and fancy spells."
"It's about marking the path."
He squatted again, tapping the damp wall with his knuckle.
"If the Vein forgets you, you never get home."
"So draw your mark — simple, clean, true..."
"No frills."
Rio went first, tongue sticking out of the side of his mouth as he scrawled what looked like a ghost with wings. Peggy slapped her chalk line right over it.
[ Rio ]
"Hey!"
[ Peggy ]
"Clean and true."
Nerim's mark curled around theirs, a slow spiral rune with tiny root hooks at the ends.
Kaiden paused. He traced a three-pronged root — simple, branching out like the old trees behind his grandfather's forge. When the chalk hit the damp wall, it shimmered faintly — a soft, living pulse under his skin.
[ * Kaiden * ]
"Roots in… roots out."
Deeper in, they found old claw marks on the stone, dulled and smoothed by time. Peggy stooped to pry up a broken pickaxe head half-buried in silt. She flicked it to Nerim, who stuffed it in his bag like he'd found a treasure.
Kaiden spotted a glint near his boot — a sliver of crystal wedged into a fissure.
When he pulled it free, the Vein seemed to hush for one heartbeat, like it exhaled into his palm.
[ HEART ]
[ Cradle Vein Scrap ]
Durability: 1/1
Market Value: Nil
Grade: Common
[ Passive ] +0.0002 INT (Vein)
Resonance: Awaiting
The crystal vanished into Voidspace — that hush behind his ribs where secrets nested like roots.
"Even the dust remembers."
◈◈◈
They traced their marks back, scuffing gravel so their boots echoed like a growing drumbeat. Rio tripped on a root stub and shrieked. Irna nearly fell when she grabbed his shoulder to steady him, but Peggy just braced her foot and stopped them both with a grunt.
When they reached the fork again, Kaiden looked back at the wall. His root-mark glowed softly — a tiny promise that the Vein would remember him next time.
Jaren rapped the tunnel wall with his knuckles.
[ Jaren ]
"Marks stand."
"Memories stick."
"You're sprouts now, but you're growing."
He jerked a thumb toward the surface.
[ Jaren ]
"Come on..."
"Sun's up there."
"Food's up there."
"And I've got better things to do than dig you out if you decide to get lost for lunch."
Rio bounded up the slope first — and cracked his head on a low beam with a squeal that echoed perfectly. Irna giggled so hard she hiccuped. Peggy smacked Rio's shoulder for good measure.
Kaiden lingered. He pressed his palm flat to the stone — cool, damp, alive. He felt the hush of roots winding through it.
Roots in.
Roots out.
Secrets waiting.
When he stepped into the sun, the tunnel mouth closed behind them like a secret sealed in stone.
And far below, the Vein shifted in the deep dark — dreaming of sprouts who might one day wake it fully.
