The moment Aiden's blade struck the core, the entire chamber shook.
A deep, resonant hum echoed through the tunnels, like the groan of a giant waking from an uneasy sleep. The swirling rings around the core twisted violently, collapsing inward as the blade pierced its center.
For a split second, everything went silent.
Then the core exploded with light.
A wave of dark energy burst outward, slamming into the walls and sending cracks racing through the concrete. Dust and debris rained down from the ceiling.
Elira stumbled back, raising her arm to shield her face. "That doesn't look stable!"
"It isn't," Aiden replied.
He didn't pull the blade out.
Instead, he pushed it deeper.
The core vibrated violently, its surface fracturing like cracked glass. Threads of unstable energy leaked from the wounds, writhing like snakes in the air.
Ignis stepped closer, her golden eyes glowing brighter.
"Careful," she said. "If it collapses too fast, the energy will burst outward."
Aiden nodded. "Then we control the collapse."
He shifted his grip on the blade and channeled a small portion of his aura into it.
Not enough to cause a spectacle.
Just enough to stabilize the energy flow around the weapon.
The blade began to glow faintly.
The core reacted immediately.
The chaotic energy around it slowed, as if being drawn into a controlled spiral around the blade.
Elira stared. "You're… containing it?"
"Trying to," Aiden said through clenched teeth.
The pressure on his arm increased. It felt like holding back a river with one hand. The core was unstable, unpredictable. Any mistake could cause it to detonate.
Ignis placed her hand lightly on his shoulder.
A faint warmth spread through his body.
"Borrow a little of my energy," she said softly. "Just enough."
Aiden didn't argue.
A thin stream of draconic aura flowed into him, stabilizing his stance.
The pressure eased.
Just enough.
The core's glow began to dim.
Cracks spread across its surface, the dark crystal-like structure splintering into smaller fragments. The swirling rings around it faded, dissolving into the air like smoke.
Elira watched, wide-eyed.
"I've never seen someone do this," she murmured. "Most hunters just smash the core and run."
"That's why most of them cause collapses," Ignis replied.
A final pulse ran through the chamber.
Then—
The core shattered.
Not in an explosion.
But in a quiet, controlled collapse.
The fragments dissolved into the air, leaving behind only faint particles of fading distortion energy.
Silence returned.
Aiden pulled his blade free and exhaled slowly.
The pressure in the air vanished, replaced by a strange emptiness.
Elira lowered her sword. "Is… is it over?"
Ignis nodded. "The artificial core is gone. The zone will stabilize on its own now."
Elira looked around the chamber, still tense. "No explosion. No collapse. No aftershock."
She glanced at Aiden. "You're not normal, are you?"
Aiden sheathed his blade. "I get that a lot."
The system activated again.
[Mission Complete]
Artificial Core Neutralized
Calculating Rewards…
Aiden felt a familiar anticipation rise in his chest.
The system rarely gave anything small.
Especially after a hidden scenario.
Primary Reward:
Attribute Increase (All Stats +2)
Secondary Reward:
Skill Unlocked – Frost Resonance
Hidden Reward (Contract Bonus):
Sealed Entity Fragment Acquired
Aiden frowned slightly.
"Sealed entity fragment?"
Ignis's expression sharpened. "That doesn't sound like a normal reward."
Elira crossed her arms. "And what's that 'Frost Resonance' thing?"
Aiden looked at the system window.
The description appeared.
Skill: Frost Resonance
You can temporarily synchronize your aura with a contracted frost-aligned entity.
Effects vary depending on the contract level.
Aiden's eyes shifted to Elira.
She raised an eyebrow. "Why are you looking at me like that again?"
Ignis smiled faintly. "Because the system thinks you're connected now."
Elira frowned. "Connected how?"
Aiden hesitated.
"Apparently," he said, "we formed a temporary contract during the mission."
She blinked. "Excuse me?"
Elira stepped closer, her expression sharp.
"I didn't agree to anything."
"The system doesn't always ask," Ignis said.
"That's ridiculous," Elira snapped. "Contracts require consent."
Ignis tilted her head. "Not system contracts."
Elira looked at Aiden again. "So what does this mean?"
"Temporary," he said. "It'll likely dissolve once the mission chain ends."
She studied him carefully.
"You're not lying," she said after a moment.
"I don't see the point."
The ground trembled faintly.
Not from the core.
But from something deeper.
Ignis's expression changed instantly. "Wait."
Aiden felt it too.
A second presence.
Faint.
But real.
From deeper within the tunnels.
Elira turned toward the far end of the chamber. "I thought this was the only core."
"So did I," Aiden said.
Ignis's eyes narrowed. "This one feels different. Smaller. But… alive."
A faint scratching sound echoed from the darkness.
Something was moving.
From the far end of the chamber, a small shape crawled out from a crack in the wall.
It was no larger than a housecat.
Its body was covered in thin, pale scales, and two tiny horns curved backward from its head. Its eyes glowed faintly with cold blue light.
Elira blinked. "…Is that a baby monster?"
Ignis stared at it, her expression unreadable.
"No," she said quietly. "That's not a monster."
The small creature wobbled forward, clearly weak. Its movements were slow, unsteady.
It let out a soft, almost pitiful sound.
Aiden's system flickered again.
[Hidden Reward Unsealed]
Entity Fragment: Frost Wyrmling
Condition met: Temporary contract with frost-aligned entity.
Would you like to hatch the fragment?
Aiden stared at the small creature.
"It already hatched," he said quietly.
Ignis nodded. "The fragment must have formed a physical body when the core collapsed."
Elira crossed her arms. "So… what is it exactly?"
Ignis's eyes softened slightly.
"A young frost dragon," she said. "Or something close to one."
Elira's eyes widened. "You're kidding."
The small wyrmling looked around weakly.
Then its glowing eyes locked onto Aiden.
It took a few shaky steps toward him.
And collapsed at his feet.
Aiden crouched down, studying it.
It wasn't aggressive.
It wasn't dangerous.
Just… exhausted.
Elira frowned. "So what now? We just leave it here?"
Ignis shook her head. "If we do, it won't survive long. The energy that sustained it is gone."
The wyrmling let out a faint whimper.
Aiden hesitated.
Then he reached down and picked it up.
It was lighter than he expected.
Cold to the touch.
But not unpleasant.
The system flickered one more time.
[New Companion Available]
Frost Wyrmling
Status: Weak, unstable
Bonding recommended for survival.
Elira stared at him. "You're not seriously thinking of keeping it."
Aiden looked at the small creature in his hands.
Then at the empty chamber around them.
"Looks like it doesn't have anyone else," he said.
Ignis smiled softly. "You're too soft sometimes."
"Maybe," he replied.
But he didn't put the wyrmling down.
Far above them, the city continued as normal.
Unaware that, deep beneath its streets, something ancient and powerful had just been born.
And chosen its first master.
