Selene's lips curved as she let out a soft chuckle.
"Oh, that," she said, her voice carrying that quiet warmth. "It's the Nexus core. It stabilizes your mana and keeps you balanced under the chamber's pressure."
Eran's smirk deepened, his thoughts playing idly as though he hadn't known but was amused by the explanation.
His gaze flicked back to the golden banner faintly glowing at his wrist.
"But… can it still stay attached if we leave the Grade C chambers?" he asked, tilting his head slightly toward her.
She leaned closer, letting her presence brush against him with quiet grace.
"Yes, Eran," she replied softly. "After the final duel that's coming in a week, we'll return to the Grade C chambers. The core will remain linked until then."
Eran exhaled slowly, as the memory of the last event flickered across his mind.
"Well," he murmured, letting a faint grin curve his lips, "I guess I won't forget… not after the one Professor Girzar conducted."
