The following account was recorded in the agent's log during your transmission: Sunlight's filtering through a series of narrow slits in the cave ceiling, casting an intricate pattern on the crystal formations jutting out of the stone floor. Umm, like, the air's crisp and clean, with a hint of cedar, and a thin layer of frost is covering everything, even though it's not cold enough to be freezing... a delicate, filigree-patterned bridge made of what looks like bone is stretching across a narrow chasm, somehow supported by the faint humming of a series of ancient, weathered tuning forks embedded in the cave walls. Water's trickling down the stone face behind me.
