The following account was recorded in the agent's log during your transmission: Towering, crystalline stalactites hang from the ceiling of this massive cave, their faceted tips reflecting shards of sunlight filtering through the ice-filled entrance. Uh, the air's crisp and still, with a faint scent of frankincense wafting from the crystalline structures, which seem to be generating a low-frequency hum in harmony with the steady dripping of water somewhere deeper in the cave. Shards of crystal are somehow passing through the solid stone walls, reassembling into impossible-looking polyhedral shapes on the other side, and the sound of their quiet passage is like a whispered chant.
