The underground corridor beneath Artemis smelled faintly of damp stone, machine oil, and old paper sealed too long away from sunlight. Low amber lights ran along the walls in narrow strips, throwing long shadows across reinforced concrete and exposed piping overhead. Somewhere deeper underground, machinery pulsed with a slow mechanical rhythm that vibrated faintly through the floor beneath Galathea Brooks's heels.
The elevator doors closed behind them with a soft hydraulic hiss.
The sound settled badly in her chest.
Cool air slid across her skin immediately, but it did nothing to calm the restless buzzing beneath her arms. Ever since the elevator reacted to her touch upstairs, the sensation had refused to disappear completely. Her nerves felt overstimulated, too aware of fabric against skin, of temperature shifts, of the low hum threading through the walls around her.
Her fingers drifted unconsciously across her opposite forearm, rubbing slowly through the sleeve of her blouse as if pressure might quiet the sensation underneath.
It didn't.
Cael Alexander noticed.
Of course he did.
His gaze flicked briefly toward the movement before returning to the corridor ahead. He said nothing about it. That somehow felt worse.
"Tell me this place at least passes safety inspections," Galathea muttered as they started walking.
"It exceeds them," he said smugly.
"That answer sounded rehearsed." Galathea closed her eyes briefly, feeling the tingle that ran up and down her arm.
"I've had nervous employees before." He shrugged.
She glanced sideways at him. "Did the building try to emotionally destabilize them too?"
"No," Cael said calmly. "That part appears specific to you."
Galathea rubbed her wrist again before shoving both hands into the pockets of her slacks.
The corridor stretched deeper beneath Artemis in long concrete sections interrupted by steel security doors every twenty feet. None of it resembled the polished architecture upstairs. The gallery above curated beauty for wealthy patrons. This place existed purely for containment.
The realization sat unpleasantly in her stomach.
Their footsteps echoed softly as they moved through the underground level. The sound bounced strangely off the walls, swallowed quickly by the heavy silence afterward.
Ahead, another reinforced door blocked the corridor.
A biometric panel glowed beside it.
Cael pressed his palm against the scanner without breaking stride. The system flashed green immediately.
Galathea eyed the locking mechanism. "You know, normal CEOs usually hide tax fraud or affairs. You built a classified dungeon under an art gallery."
"One of those things is significantly more expensive." He playfully winked at her.
She exhaled through her nose despite herself.
The door unlocked with a heavy mechanical click.
Beyond it, the corridor widened slightly. The temperature dropped another few degrees.
Galathea instantly regretted not grabbing her blazer before leaving the office upstairs.
Again.
The air down here felt old in a way modern buildings usually didn't. Not dirty. Not abandoned. Just layered with time. Even the concrete looked older than it should have, worn smooth in places from years of unseen movement.
Another vibration traveled faintly through the walls.
Galathea slowed.
Her hand rose automatically again, fingers brushing lightly over the inside of her forearm.
Buzzing.
Still there.
The sensation sharpened the deeper they went.
Cael noticed her slowing pace this time and adjusted his own without comment. Not crowding her. Not pushing.
Matching.
Unfortunately, she noticed that too.
"You're staring again," she said quietly.
"I'm assessing," he corrected.
"That sounds creepier somehow," she said, indifference still dominating her tone.
A faint glint of amusement appeared briefly in his eyes.
"You keep touching your arm since the elevator," he said.
Galathea immediately dropped her hand. "I'm aware."
The corner of his mouth shifted slightly.
Gods, she hated when he looked entertained.
Ahead, the corridor narrowed again before opening abruptly into a circular security chamber. Thick steel doors lined the walls, each marked only by numbers instead of labels. Overhead cameras tracked movement silently.
This part looked newer.
More expensive.
More dangerous.
Galathea folded her arms lightly against the cold. "You know, if somebody murders me down here, the documentary interviews afterward are going to be very embarrassing for you."
Cael keyed another access code into a wall panel. "You assume they wouldn't blame you instead."
"That's fair," she admitted. "I do have suspiciously good motive at this point."
A quiet chuckle escaped him.
The sound warmed the room more effectively than the industrial heating system.
That irritated her immediately.
The final security door unlocked with a heavier sound than the others.
Then it opened.
Galathea stopped walking.
The vault beyond was enormous.
The space had been carved directly into the bedrock beneath Artemis, rough black stone arching high overhead in uneven natural curves interrupted by steel reinforcement beams. Industrial lighting hung from suspended tracks above, casting pale pools of light across the floor while leaving entire sections of the chamber swallowed in shadow.
The temperature dropped sharply inside the vault.
Cold settled immediately into her lungs.
The room smelled like varnish, dust, minerals, and something older she couldn't name.
At the center of the chamber stood seven stone pedestals arranged in a wide circle.
Galathea's attention locked onto them instantly.
The pedestals weren't decorative. They looked ancient. Black stone scarred by age and etched with thin silver markings that seemed to shift slightly if she stared too long.
Six stood empty.
One glowed softly.
Galathea stepped forward before realizing she had moved at all.
The buzzing beneath her skin intensified immediately.
Her fingertips prickled.
The glowing pedestal stood slightly taller than the others. Resting atop it was a silver sculpture shaped like an open human hand.
A silver brush lay across the palm.
The metal emitted a faint pale glow that pulsed slowly against the surrounding darkness.
Alive.
That was the problem.
Metal should not look alive.
Galathea rubbed her palm slowly against her thigh before realizing she was doing it again.
"What is that?" she asked quietly.
Cael stopped beside her. Close enough that she could feel warmth from him against the underground cold.
"That," he said, "is a Masterpiece Key."
Galathea kept staring at the object. "That sounds aggressively fictional."
"It sounded worse the first time somebody explained it to me too." Cael said, nodding slowly.
Her gaze shifted briefly toward him. "You expected me to react better than this?"
"No," Cael admitted calmly. "Actually, this is going smoother than expected."
"That is deeply concerning information, Alexander." Galathea tisked.
His mouth curved faintly at the surname. She seldom called him by name.
Galathea looked back toward the pedestal.
The silver glow pulsed once.
Her skin buzzed harder immediately afterward.
This time she pressed her fingers against the inside of her wrist firmly, grounding herself in physical sensation.
It barely helped.
"Why are the others empty?" she asked.
Cael's expression shifted subtly then. Not colder. Heavier. "Because the remaining Keys are missing."
"Missing how?" she asked.
"Different ways." His gaze moved across the empty pedestals slowly. "Some were stolen. Some disappeared. Some were destroyed intentionally."
Galathea looked at the vacant stone stands again.
Six empty spaces suddenly felt louder than the occupied one.
Like missing teeth.
"How long has this place existed?" she asked again.
"Long before Artemis," he answered.
She frowned slightly. "That is not a number."
"It's the only honest answer I can give right now," he angled his head slightly.
The low mechanical hum inside the vault deepened faintly around them.
Galathea's eyes narrowed. "You hear that too?"
"I do." Cael answered but he was seemingly unbothered.
The sound didn't resemble machinery anymore.
It sounded responsive.
The realization made the buzzing beneath her skin flare sharply enough that she rubbed both hands slowly along her forearms this time.
Cael watched the movement carefully.
Not with concern exactly.
Recognition.
"You're overstimulated," he said quietly.
"Wonderful. Love that for me," she said sarcastically,
"You should step back slightly," Cael suggested
"I don't think the magic sculpture is my biggest issue right now," Galathea said.
"It is when it starts reacting," he pointed out.
Galathea looked toward him sharply. "Starts reacting?"
The silver glow brightened.
Both of them turned immediately.
The brush trembled lightly against the metal palm.
Galathea froze.
The movement was subtle.
Unmistakable.
"No," she said under her breath.
The silver fingers twitched once.
Then again.
The buzzing beneath her skin spiked violently.
Her hand shot toward her arm instinctively, gripping just below her elbow hard enough to ground herself physically.
The pedestal markings lit faintly beneath the artifact.
Cael's posture changed immediately beside her.
Focused now.
Alert.
"It hasn't moved in years," he said quietly.
Galathea stared at the hand. "That sentence should have come earlier."
The silver fingers flexed slowly.
Like cramped joints waking after a long sleep.
A pulse of pale light rolled outward from the pedestal.
The entire vault hummed.
Galathea inhaled sharply as warmth climbed rapidly beneath her skin. Her palms tingled painfully now. Not heat exactly. Pressure.
Recognition.
The silver hand turned slightly.
Toward her.
Her stomach dropped hard enough that she physically stepped backward.
The hand followed.
"Oh, absolutely not," Galathea whispered.
Cael remained beside her, attention fixed entirely on the artifact now. "It recognizes you."
"That is not comforting phrasing either," Galathea said, eyes planted on the sculpture.
The brush trembled harder against the silver palm.
The glow brightened across the floor markings, tracing lines through the stone like veins beneath skin.
Galathea rubbed her forearm again frantically now, trying unsuccessfully to settle the sensation crawling beneath her nerves.
The vault responded immediately.
The lights overhead flickered once.
Cael noticed both reactions simultaneously. "Stop touching your arm, Sweetheart."
Galathea looked at him incredulously. "That feels impossible currently."
"Galathea." Something in his voice made her stop.
Not authority.
Urgency.
Slowly, she lowered her hand.
The vault quieted slightly afterward.
Both of them noticed.
Her pulse jumped.
"That was me?" she asked quietly.
"Yes," he whispered his answer.
The silver hand lifted one finger.
Just slightly.
Like reaching.
The sight rooted her completely in place.
A sharp pulse moved through her chest suddenly, strange and disorienting. Images flickered at the edge of her vision too quickly to fully form-- painted streets, silver light, unfinished buildings beneath impossible skies.
'Seer.' The word slid through her mind again like something remembering her.
Galathea's breathing turned uneven.
Cael shifted closer instantly.
Not touching.
Ready.
She noticed the restraint immediately now. The deliberate space he always maintained whenever things escalated around her.
The memory of the elevator flashed sharply through her head.
Touch intensifies reaction.
The realization landed harder underground.
The silver hand trembled again.
The brush shifted slightly against the palm.
Galathea felt the response physically this time. Not emotionally. Physically.
Like invisible threads pulling somewhere beneath her skin.
She pressed her lips together hard. "What does it want?"
Cael's gaze remained fixed on the pedestal. "You."
Her laugh came out thin and disbelieving. "That feels dramatic."
"I'm being conservative," he murmured.
The hand flexed again.
Stronger now.
The entire vault hummed louder in response.
Galathea instinctively stepped closer instead of away.
Cael noticed immediately.
She stopped herself at once.
Too late.
The glow intensified sharply.
Silver light spilled across the stone floor around the pedestal, illuminating symbols carved deep into the rock beneath it.
Galathea stared downward.
The markings resembled brushstrokes.
No.
Writing.
Ancient lettering curved beneath the pedestal in concentric circles worn smooth by time.
The buzzing beneath her skin became unbearable.
Her fingers drifted toward her wrist again automatically.
Cael caught the movement immediately this time. "Don't."
His voice dropped lower.
Closer.
Galathea looked up at him instinctively.
Oh, it was a mistake.
He was already watching her with that same focused intensity from the elevator. Calm on the surface. Restrained underneath it.
And something else now too.
Recognition.
Like he was watching a theory become real in front of him.
The realization unsettled her more than the moving artifact.
The silver hand lifted slightly from the pedestal.
Not fully.
Enough.
Galathea's breath caught hard. "Gods."
The brush vibrated faintly against the metal fingers.
Then the hand tilted.
Toward her again.
The vault seemed to inhale around them.
Cael stepped closer immediately-- not touching, just near enough that warmth cut through the underground cold.
"It knows you," he said softly.
The silver glow pulsed once more.
And somewhere beneath Artemis, something ancient finally stopped sleeping.
