The following account was recorded in the agent's log during your transmission: Massive crystal formations, like, tower above the waterline in this sprawling, submerged city. The air's really pressurized, and it smells kinda like damp concrete, but there's no silt or sediment anywhere – the water's crystal clear. Schools of bioluminescent fish dart past these intricately carved stone doorways, which somehow still have working doors that creak open and shut on their own, even underwater. The sunlight filtering down from above casts this surreal, wavy glow on everything, and... a thin stream of bubbles somehow rises into the air from the seafloor, only to get sucked back down into a small, circular opening.
