— Back in the human capital

  The horses did not slow.

  Captain Rhylas rode at the front of the formation, cloak pinned tight against the wind, expression carved from discipline.

  Behind her, five cloaked figures moved in silence.

  Unit Three.

  Mage. Tracker. Spear specialist. Barrier caster. Interrogator.

  Officially, they were being dispatched to investigate abnormal mana density in a frontier forest.

  Unofficially—

  They were assessing a potential catastrophe.

  Rhylas spoke without turning.

  “Report.”

  The squad mage adjusted the crystal device mounted to his forearm.

  “Mana saturation remains elevated. Stabilized but unnatural.”

  “Source?”

  “Single epicenter. No summoning circle residue. No divine descent signature.”

  Rhylas narrowed her eyes.

  “…So someone did that.”

  “Yes, Captain.”

  She looked toward the distant horizon.

  “Then we determine who and whether they need to be contained."

  They did not know it yet.

  But they were riding toward something that had already begun evolving.

  The water never receded.

  It settled.

  The forest did not return to normal.

  It adapted.

  What used to be dry earth became marshland.

  Sunken trunks jutted from shallow water like broken ribs.

  Mist lingered constantly.

  And in the center—

  Stone had risen.

  At first it was dismissed as exposed ruins.

  Then the archway formed.

  Then the steps.

  Then the pressure.

  Now no one argued.

  It was a dungeon.

  And everyone knew what that meant.

  Akira stood at the edge of the guild’s balcony overlooking the southern road.

  The Sunken Woods were barely visible in the distance.

  “…It looks calm from here,” he muttered.

  Kristyne stood beside him.

  “It didn’t look calm when you flooded it.”

  He winced.

  “Do you have to say it like that?”

  “You flooded it.”

  “I get it.”

  She smirked faintly.

  Five weeks had passed.

  In that time:

  Akira had trained daily.

  Controlled output scaling.

  Learned to stop at eighty percent without internal strain.

  Avoided ten percent entirely.

  He realized that the ring only works with water magic.

  His body had changed.

  Subtly.

  Mana flowed faster.

  Cleaner.

  He could feel density differences in the air now.

  Even now—

  Stolen novel; please report.

  He could feel the woods.

  Like a low-pressure system in the distance.

  “…It’s still growing,” he said quietly.

  Kristyne nodded.

  “I can feel it too.”

  Malis approached from behind them.

  “Mana crystallization has begun in the lower layers.”

  Akira didn’t look back.

  “How bad?”

  “Unknown.”

  “Worst case?”

  Malis tilted his head slightly.

  “Adaptive monster core formation.”

  Kristyne blinked.

  “…That sounds bad.”

  “It is.”

  Akira exhaled slowly.

  “…So it’s my fault.”

  Malis corrected calmly.

  “It is your consequence.”

  Akira didn’t argue.

  Because that was fair.

  Silence lingered for a moment.

  Then Kristyne nudged him lightly with her shoulder.

  “You’re not regretting it.”

  He didn’t answer immediately.

  “…No.”

  She nodded.

  “I didn’t think so.”

  He looked at her.

  “You still mad?”

  “No.”

  “Still scared?”

  “…Yes.”

  He didn’t joke this time.

  He reached for her hand instead.

  “I won’t use anything over two percent again.”

  “Good.”

  Malis observed quietly.

  Filed it away.

  The bond between them was no longer fragile.

  It had been tested.

  It held.

  And that mattered more than either of them realized.

  A guild bell rang below.

  Akira looked down.

  A crowd had gathered around the quest board.

  “…That’s new.”

  The parchment was larger than the others.

  Stamped with a silver seal.

  Emergency Expedition Request — Sunken Woods

  Uncharted dungeon structure confirmed.

  Entrance stable. Interior unmapped.

  High mana density. Mutated wildlife reported.

  Seeking capable adventurers to explore and map interior structure.

  Reward: 25 Gold Coins.

  All discovered treasure may be retained.

  Akira read it twice.

  Then once more.

  “…Twenty-five.”

  Kristyne blinked.

  “That’s not normal.”

  “No.”

  Malis stepped closer to the board.

  “Risk premium.”

  Akira glanced at him.

  “Meaning?”

  “Meaning the guild expects casualties.”

  The surrounding adventurers murmured.

  “Twenty-five though…”

  “That’s capital-level pay.”

  “Mutated monsters, they said.”

  Akira’s gaze returned to the words:

  Uncharted dungeon structure confirmed.

  He felt it again.

  That low pressure.

  Pulling.

  Like something he started had finished forming.

  Kristyne crossed her arms.

  “You’re thinking it.”

  “Yes.”

  “You’re going to say it anyway.”

  “Yes.”

  She sighed.

  “…Say it.”

  Akira turned toward her.

  “It’s my mess.”

  A nearby adventurer glanced over.

  “Your mess?”

  “Nothing,” Akira said quickly.

  Kristyne lowered her voice.

  “We don’t even know what’s inside.”

  “Exactly.”

  “That’s not comforting.”

  Malis spoke calmly.

  “Capital forces are approaching.”

  Akira stiffened.

  “…How long?”

  “Within a week, at current pace.”

  Kristyne looked between them.

  “You knew?”

  “I predicted.”

  Akira’s jaw tightened slightly.

  “If they get there first—”

  “They claim jurisdiction,” Malis finished.

  Silence.

  Akira looked back at the notice.

  Twenty-five gold.

  Keep the treasure.

  High mana density.

  Mutated wildlife.

  His dungeon.

  Kristyne studied him carefully.

  “You’re not doing this because of the gold.”

  “No.”

  “You’re not doing it for glory.”

  “No.”

  She exhaled slowly.

  “You’re doing it because if something worse forms in there…”

  “…It’s on me.”

  Kristyne stared at the quest board.

  Then at him.

  Then back at the board.

  “…If we go in,” she said slowly, “we go in prepared.”

  “Obviously.”

  “No rushing.”

  “No.”

  “No using anything stronger than two percent.”

  “Definitely no.”

  She narrowed her eyes.

  “Promise.”

  “I promise.”

  Malis folded his arms.

  “Then The Gods’ Plan accepts its first dungeon.”

  Akira grimaced.

  “Can you stop saying it like that?”

  “No.”

  The guild hall buzzed with tension.

  Some adventurers were already backing away from the board.

  Others were arguing over party formations.

  Twenty-five gold was tempting.

  But not tempting enough for most.

  Akira stepped forward.

  Hand hovering slightly over the posting.

  Kristyne stood beside him.

  Not stopping him.

  Not pushing him.

  Just there.

  Grounding.

  Malis watched.

  Expression unreadable.

  Outside—

  The Sunken Woods pulsed faintly.

  And far down the southern road—

  Six mounted figures approached the city gates.

  The board was moving again.

  And this time—

  Akira was stepping toward the center of it.
