"It took my spirits a full week to find the key hole," she grunts, deep in concentration. "He hid it well. All this wall looks about the same, the only reason they were able to find it is because of the different frequency of power given off, since the key hole is shallower than the rest of the wall."
Tapping the mirrored wall a few times with the flat of her hand, she listens for a moment, mulling over the shallow sound that echoes back and nods in affirmation. This is it.
Hurriedly, she slams the key into the lock, twisting and turning it, fiddling around with it for a bit in an effort to release the latches inside it. A few grunts slip from her mouth as she strenuously tries to move the key in the latch, attempting to figure out the mechanism in the limited time she knows we have.
