The following account was recorded in the agent's log during your transmission: Gigantic, crystalline formations rise from the seafloor, illuminated by an ethereal blue glow emanating from a series of... uh, what looks like bioluminescent, fiber-optic "trees" that seem to be drawing in nearby schools of deep-sea fish. The air pressure's extreme, and the smell of seaweed and saltwater's almost overwhelming, as a massive, impossibly intact Kryptos sculpture – like, the exact same one from the CIA courtyard – sits in the center of the formation, slowly rotating despite the crushing weight of the water. It's pitch black beyond the blue glow, but I can sense a low-frequency hum emanating from the formations.
