The following account was recorded in the agent's log during your transmission: Dank, moss-covered stones form a labyrinth beneath an ancient, vaulted ceiling, the air thick with moisture. Like, it smells strongly of damp earth and ozone-free water. Water trickles from stone gutters into a network of slow-moving streams and shallow pools that seem to be supporting some kind of glowing, iridescent aquatic life. It's somehow snowing gently in this underground space, with flakes landing and dissolving instantly into the water.
