The chamber responded again, not with force, but with quiet alignment.

Alicia’s earlier manipulation had left a trace the room had not yet discarded. As she studied the wall near the sealed archway, her attention settled on the faintly glowing sigil where the refracted light had briefly converged. Up close, the rune was not etched in the usual manner. It seemed embedded beneath the surface, revealed only when struck by the correct angle of light. Its shape was delicate, angular, and incomplete, as though only one part of a larger pattern had been awakened.

As her fingers brushed the surface, the glow did not fade. Instead, it pulsed once, softly, acknowledging the contact. The crystal behind them continued its steady rotation, but now that the group had seen it, the pattern became clearer. The light was not random. It was searching.

Sa’Saori’s observation of the mirrors proved equally important. The permeable surface did not resist her blade. The tip passed through with only the faintest distortion, like pushing through a thin veil of water. On the other side, the reflection did not match the chamber perfectly. The angles were slightly off. The central crystal appeared lower, its light dimmer, its beams less scattered.

And then, just for a moment, something else bled through.

The floor in that reflection was not smooth crystal. It was segmented. Layered. Structured in a way that resembled interlocking shapes far less refined than the Vestibule’s design.

The image corrected itself almost immediately.

The mirror stilled.

Across the chamber, another faint glimmer appeared along the wall near the door. Then a second. Then a third. Dim, incomplete sigils, each waiting to be struck by the proper beam of light.

The puzzle revealed its next layer.

The crystal did not need to be stopped.

It needed to be guided.

And the room, patient as ever, continued to watch.
