The following account was recorded in the agent's log during your transmission: Cobalt blue stalactites hang from the low ceiling of this vast, underground ossuary, and a thick layer of fine, sparkling dust coats every available surface, including the intricately carved, ancient reliquary chests that line the room. The air's heavy with the scent of damp earth, and it's got a light electric charge that's making my skin prickle... a low hum's coming from somewhere, like a really quiet earthquake, but the ground isn't shaking. Umm, the dusty surface of a nearby reliquary has been recently disturbed, and whatever made the mess left a small pile of iridescent feathers behind.
