The following account was recorded in the agent's log during your transmission: Uh, it's a massive, underground salt dome, the air's thick with this damp, mineral scent. Towering crystalline columns are rising out of the salt, their facets reflecting this faint, otherworldly light that's somehow coming from the walls themselves... like the salt's emitting a soft, blue-green glow. The sound of dripping water's echoing through the space, and for some reason, a section of the salt wall is slowly unmaking itself, unraveling into nothing like a thread being pulled loose, revealing this absolute blackness behind it.
