The following account was recorded in the agent's log during your transmission: A maze of rough-hewn, cyclopean stone corridors stretches out in every direction, their weathered walls bearing the faint, eerie symbols of an ancient, forgotten language. The air's thick with the musty smell of damp earth and something else... ozone, and the flicker of faint, luminescent lichen growing in the cracks casts an eerie, subterranean light on the scene. It's heavy with an electric charge that crackles and spits, making the fine hairs on the walls quiver. Water seems to be seeping upwards from the rough flagstones, like the entire place is underwater yet somehow defying gravity.
