The following account was recorded in the agent's log during your transmission: Rusted steel latticework supports this crumbling, old observation dome half-buried in a coral reef, the air thick with seaweed stench and a lingering, heavy fog. It's really damp, cool, with the sounds of... uh, dolphins outside. Like, beyond the cloudy dome's windows, a slow whirlpool's dragging glowing bioluminescent organisms around in a mesmerizing dance, even though the ocean seems really still. In here, a half-disassembled underwater drone lies abandoned, a mess of wires, and one control panel has what looks to be the sigils from The Key of the Abyss painted onto its face, pulsing with the same blue light as the whirlpool outside.
