Sarah trapped by Exxilon's embrace

The carved frieze depicting a C with a central dot responds to Sarah’s touch by rotating in 90-degree increments. Though static in appearance, the frieze’s rotation activates a sequence of mechanisms within the chamber walls, inadvertently signaling Sarah’s presence to the city's long-dormant Exxilon inhabitants.

Before: A dormant stone frieze set into the wall, smooth and unrotated, its function hidden

After: Partially rotated after Sarah’s touch, its movement triggering the chamber’s responsive mechanisms
