The following account was recorded in the agent's log during your transmission: Rubbles of grey-brown concrete scatter the surface of the seafloor like they're just a regular occurrence here... in what appears to be a half-flooded temple or monument – an open plaza surrounded by four, roughly-cut monoliths, and a vaulted stone roof's been partially caved in, so ocean currents flow straight through. The air is ice cold, smells brackish... like when seawater's mixed with freshwater and whatever's seeping out of these pillars. Schools of... probably-deep-sea fish dart in the shade of these monoliths, bioluminescence on their spines tracing cursive Arabic script as they swim around Keter of Malkuth symbols etched into stone.
