The temporary headquarters for Warden IX's patrol unit occupied the second floor of a small hotel three blocks from Calton Mart.
It was far from luxurious. The beige walls were fading, the hallway carpet had worn thin in the center from years of foot traffic, and the elevator let out a sharp ding every time the doors closed. Rein was in no position to critique a Warden's choice of lodging. He followed Seraphine through the back entrance, past two guards who stepped aside the moment they saw her coat, up the stairs to the second floor, and stopped in front of Room 214.
Seraphine opened the door.
"Inside."
The room was tidy in a way that felt forced. It wasn't the neatness of comfort, but the order of someone used to a nomadic life, knowing that organization was the only form of control she could maintain regardless of where she was.
A large suitcase sat in the corner. A desk was piled with documents stacked with surgical precision. A spare coat hung behind the bathroom door. There were no photos, no decorations, and nothing that looked like a personal possession only the gear of someone on duty. Rein glanced around briefly before standing near the door with his hands at his sides.
Seraphine removed her outer coat, hung it up, and sat on the edge of the bed. For the first time since they met in the alley, she wasn't in a combat stance. Her shoulders dropped slightly, a movement so subtle Rein almost missed it.
"Sit," she said, gesturing toward the desk chair.
Rein sat.
Several seconds passed in silence. Outside the window, the city was slowly returning to life. The sirens had stopped. Occasionally, an Aegis Sacra vehicle rumbled past, but the sounds grew infrequent. The threat had passed.
Seraphine stared at the floor, not daydreaming but rather organizing her thoughts before speaking.
"You understand the consequences of what happened earlier," she said finally.
"Soul Return," Rein answered.
"More than just that." She lifted her gaze. "A Resonance Call has occurred between us. Your Core Crystal has opened for the first time, and that cannot be undone."
Rein remained silent, waiting.
"After the first Resonance Call, a bond between Caller and Bearer forms automatically. This isn't a choice; it's magical biology." Seraphine spoke with the same clinical tone she might use for a battlefield report. "Your Core Crystal now recognizes my resonance. This means it will be easier for me to summon you in the future, and it may be difficult perhaps impossible for any other Caller to do so."
"So, technically, I can only be summoned by you now."
"Yes."
Rein processed this for a moment.
"And you," he continued quietly, "are Warden IX of the Aegis Sacra, currently in a crisis because you lacked a weapon."
Seraphine didn't answer, but she didn't deny it either.
"So this isn't exactly a happy coincidence for either of us," Rein remarked.
"No." For the first time, a trace of exhaustion seeped into her voice. "It is a complicated situation."
Silence fell again. Rein looked at his hands, which were still trembling slightly. The shaking had lessened but hadn't stopped completely. Minor Soul Erosion. He remembered the theory from the academy. Usually, it required rest and simple physical contact a hug or a warm touch to stabilize the energy for such a mild case.
"Soul Return first," Seraphine said suddenly, as if reading his mind. "We'll discuss the rest once you're stable."
"I'm not in bad shape."
"Your hands are still shaking."
Rein looked at his hands again. There was no point in arguing with the facts.
"Okay."
Seraphine stood up and walked toward him. She stopped directly in front of his chair and knelt slightly so they were eye-level. The movement was pragmatic, devoid of any unnecessary awkwardness, yet Rein felt a strange discomfort in his chest that had nothing to do with Soul Erosion.
"For a mild case," she explained, "physical contact is sufficient. I will hold your hands."
"That sounds less terrifying than I imagined."
"Be quiet."
She took both of his hands, palms facing up, and closed her fingers over them with firm pressure. The warmth was immediate. It wasn't the searing heat of the fire from earlier; this was deeper, like something that was always meant to be there finally returning to its place. The trembling in Rein's fingers subsided as his tensed muscles finally found permission to relax.
Rein didn't move. Neither did Seraphine. For several minutes, they simply stayed there two people in a tidy but empty hotel room, one holding the other's hands, while outside the window the city of Calton returned to its normal rhythm, unaware that something had changed permanently on the second floor.
"Done," Seraphine said at last.
She released his hands and stood up, returning to her usual rigid posture as if nothing had happened. Rein moved his fingers. The trembling was gone.
"Thank you."
Seraphine didn't reply. She sat back on the edge of the bed, crossing one leg over the other, and watched Rein with an evaluative expression.
"Now, we talk."
"Your name is Rein Calvert. Former Grey Bearer, expelled from Ignis Bellum Academy last year. Currently working as a cashier at Calton Mart." She recited the facts like a checklist. "I've accessed your academy files since we were in the field."
Rein was slightly surprised. "That was fast."
"I am a Warden. Access to the academy database is standard protocol." Seraphine continued. "Your Core Crystal was classified as Dormant: non-elemental, impossible to summon. Twenty-three Callers, zero successes." She paused. "But what emerged today was Obsidian. Fire. And not just any Obsidian."
"Do you know the class?"
"I have held several Obsidian swords in my life." Her tone was steady, but something flickered in her eyes. "The one today was different. Heavier. Hotter. Fuller." She chose the last word carefully. "If I had to guess, it's a First-Class Dormant Obsidian. There hasn't been a Bearer with that classification in fifteen years."
Rein was silent. "So it wasn't because my Core Crystal was broken all this time."
"There is nothing broken about your Core Crystal." Seraphine looked him in the eye. "It was waiting for the right resonance. Those twenty-three Callers weren't deep enough. It wasn't their fault, and it wasn't yours. You were simply a mismatch."
"And you are a match."
"Apparently so."
Rein leaned back in his chair. He should have felt a flood of emotions shock, anger, relief, confusion but instead, he felt a strange sense of peace. It was like a puzzle piece finally clicking into place.
"What does this mean for me, practically speaking?"
Seraphine hesitated. It wasn't doubt, but rather choosing how to deliver information she had known for a while.
"It means," she said finally, "your situation has changed. Your Core Crystal is open and bound to my resonance. As the Warden who performed the Resonance Call, I have legal obligations toward you."
"The obligation of Soul Return."
"That is one of them." She watched him. "But also the obligation of protection. The obligation of maintenance to ensure your Soul Gauge isn't depleted without care. Under Aegis Sacra law, you are now officially under my charge as a Warden."
Rein processed the words. "So, I went from being a minimarket cashier to being legally under the charge of Warden IX."
"Yes."
"Mr. Hendra is going to be very confused when I don't show up tomorrow."
Something moved across Seraphine's face. It was fast and tiny, but Rein was almost certain it was a suppressed urge to laugh.
"I will handle the administration," she said, returning to her flat tone.
"There is one more thing," Seraphine continued. Her tone shifted slightly; it was still controlled, but there was a caution that hadn't been there before. "My position as Warden IX is currently unstable. To maintain my rank, I need an active weapon registered in the Aegis Sacra database. Before today, I didn't have one."
"And now you have me."
"And now I have you." She repeated the words without irony. "That means you will be with me. In missions, in travel, in operations. This is not a part-time job."
Rein looked down at his orange cashier uniform. Then he looked back at Seraphine.
"What's the pay?"
This time, Seraphine actually paused. "There is a standard compensation for active Bearers within the Aegis Sacra system."
"How much?"
She named the figure. Rein went quiet. The amount was nearly four times his monthly salary at Calton Mart.
"Okay," Rein said.
Seraphine stood up, walked to her desk, and took a document from the top of the stack. She placed it before Rein along with a pen.
"A temporary contract. The first three months are an adjustment period. After that, we evaluate."
Rein read the document. It was concise and the legal jargon wasn't too complex for someone who had spent two years at the academy. He signed it. Seraphine took the document back, folded it, and placed it in her suitcase.
"Tomorrow morning, we return to Aegis Sacra headquarters." She turned away. "Tonight, you can use the sofa or request a separate room. There is one empty room on this floor for squad members."
"Separate room."
"Very well." She took a room key from the desk drawer and handed it to Rein. Room 211.
Rein took it, stood up, and walked toward the door. At the threshold, he stopped.
"Warden Aldcroft."
Seraphine turned.
"Thank you," Rein said. "For what happened in the alley."
Seraphine looked at him for a moment. Her expression didn't change, but there was a look in her eyes that suggested she wasn't used to being thanked for things she considered her duty.
"Rest," she said finally. "Tomorrow will be a long day."
Rein nodded and left. In Room 211, which was smaller and simpler than 214, Rein lay on the bed with his eyes open, staring at the ceiling. His orange cashier uniform hung over the back of the chair.
In his chest, in the place that had felt empty and silent for nineteen years, there was something warm. It wasn't a blaze, just a steady heat like a coal that had finally remembered it was meant to burn.
He closed his eyes. Outside, the city of Calton continued through the night. And the monotonous life of Rein Calvert with its morning shifts, cold coffee, and shelves he tidied alone was over.
