The following account was recorded in the agent's log during your transmission: A bright, pulsing lichen covers every available surface of this underground cathedral, reflecting a warm, diffuse light that seems to be emanating from within the fungi itself. Umm, the air's thick with the scent of damp earth and has a heavy, electric charge, like it's about to storm. Water's trickling down intricate stone carvings that depict some sort of forgotten, Lovecraftian deity, and a flock of blind, iridescent birds are roosting in the rafters, somehow weaving the fungal growths into what looks like a series of eerie, living tapestries.
