The Vault did not stop trembling for a long time.
Aria sat on the cold stone floor, her breath coming in shallow bursts, her palms pressed flat against the ground as though she needed to anchor herself to something solid. The fragment's pulse still throbbed beneath her ribs—slower now, weaker, but present. Always present.
The Demon King stood a few steps away, watching her with that same unyielding stillness that made him feel less like a man and more like a force carved out of shadow.
When she finally managed to speak, her voice was raw. "She's getting stronger."
"Yes."
"And you brought me here anyway."
"Yes."
Aria let out a shaky laugh. "You're unbelievable."
"So I have been told."
She glared at him, but the anger didn't hold. Not when her body still felt like it had been hollowed out and filled with fire. Not when her mind still echoed with the fragment's voice. Not when the Vault itself seemed to pulse with memories that weren't hers.
Aria pushed herself upright. "What now?"
"You leave the Vault."
"That's it?"
"For now."
Aria shook her head. "You're infuriating."
He didn't respond.
He simply turned and began walking toward the exit. Aria followed, her legs unsteady, her thoughts a tangled mess. The Vault door closed behind them with a deep, resonant thud that echoed through the corridor.
As they walked, Aria pressed a hand to her chest. The fragment pulsed faintly, like a heartbeat muffled beneath layers of stone.
You cannot hold me forever.
Aria flinched. "Stop talking."
The Demon King glanced at her. "She speaks again."
"Yes."
"What does she say?"
Aria hesitated. "That I can't hold her."
He nodded once. "She is testing you."
Aria frowned. "Testing me how?"
"By pushing against your will. By seeing how easily you bend."
Aria clenched her jaw. "I'm not bending."
"You are resisting. That is different."
Aria groaned. "You're impossible."
"So I have been told."
They reached the upper levels of the Citadel, where the air was warmer and the runes glowed brighter. Aria leaned against the wall, trying to steady her breathing.
The Demon King watched her quietly. "You are exhausted."
"No kidding."
"You must rest."
Aria shook her head. "Resting doesn't help. She's louder when I'm still."
"That is because she seeks your attention."
Aria stared at him. "She's not a child."
"No. She is a primordial being bound inside a mortal vessel. But the principle is similar."
Aria blinked. "Did you just compare an ancient god to a toddler?"
"Yes."
Aria stared at him for a long moment. "You're… not what I expected."
"What did you expect?"
"A monster."
He didn't react. "I am."
Aria shook her head. "Not like I thought."
He didn't answer.
Instead, he gestured for her to follow again. They walked through a long corridor lined with tall windows. Outside, the Shadow Realm churned with swirling darkness and rivers of silver light.
Aria stopped at one of the windows, pressing her hand to the cold glass. "She said this place was her home."
"It was."
"And now it's yours."
Aria swallowed hard. "I don't want it."
"It does not matter what you want."
Aria glared at him. "You keep saying that."
"Because it remains true."
She turned away from the window. "Why do you care what happens to her?"
"I do not."
Aria frowned. "Then why help me?"
"Because if she awakens, the realms will fall."
Aria's stomach twisted. "So I'm just… a shield."
"You are a vessel."
"That's not better."
"No."
Aria groaned. "You're terrible at comfort."
"I am not offering comfort."
"Clearly."
They reached a small chamber near the top of the Citadel. The door opened silently, revealing a room lit by soft silver light. A single stone bed sat against the wall, surrounded by runes that pulsed faintly.
Aria stepped inside. "This isn't my room."
"No."
"Then what is it?"
"A warded chamber."
Aria stiffened. "Warded how?"
"To suppress her influence."
Aria's breath caught. "You mean… she can't reach me in here?"
"She can reach you. But she cannot overwhelm you."
Aria pressed a hand to her chest. "Why didn't you put me here before?"
"You were not ready."
Aria groaned. "You keep saying that too."
"Because it remains true."
She stepped further into the room. The air felt different here—lighter, clearer, as though the weight pressing against her mind had eased slightly. The fragment's pulse softened, becoming a faint warmth instead of a burning presence.
Aria let out a slow breath. "This is… better."
"Yes."
She sat on the edge of the bed, her body sinking into the cool stone. The runes glowed softly beneath her feet, casting gentle light across the room.
The Demon King stood in the doorway. "You will rest here tonight."
Aria nodded. "And tomorrow?"
"Your training continues."
Aria groaned. "Of course it does."
He didn't move.
He simply watched her, silent and unreadable.
Aria frowned. "What?"
"You are afraid."
"Obviously."
"You hide it well."
Aria looked away. "I'm not trying to hide it."
"You are."
She clenched her jaw. "Why does it matter?"
"Because fear shapes the fragment."
Aria turned to him sharply. "What does that mean?"
"She responds to your emotions. The stronger they are, the stronger she becomes."
Aria's stomach twisted. "So if I'm scared, she gets stronger?"
"Yes."
"And if I'm angry?"
"Yes."
"And if I'm… anything?"
"Yes."
Aria pressed a hand to her forehead. "That's impossible. I can't just stop feeling."
"You must learn to control your reactions."
Aria stared at him. "You're asking me to be emotionless."
"No. I am asking you to be disciplined."
Aria shook her head. "I don't know how to do that."
"You will learn."
She looked at him for a long moment. "Why do you care if I succeed?"
He didn't answer immediately.
When he finally spoke, his voice was quiet.
"Because if you fail, I will have to kill you."
Aria froze.
He didn't look away.
"And I would prefer not to."
Aria's breath caught. "Why?"
He stepped back, his expression unreadable. "Rest."
The door closed behind him.
Aria sat in silence, her heart pounding, her thoughts spinning.
The fragment pulsed faintly beneath her ribs.
He fears me.
Aria swallowed hard. "He fears what you'll do."
He fears what you will become.
Aria shook her head. "No."
Yes.
Aria pressed her hands to her ears. "Stop."
You cannot silence me.
Aria curled onto the bed, her breath trembling.
The runes glowed softly.
The room hummed gently.
The fragment quieted.
But not fully.
Never fully.
Aria closed her eyes.
And for the first time since the ritual, she slept without dreaming.
