The following account was recorded in the agent's log during your transmission: Tendrils of a sprawling, bioluminescent vine are wrapping around the stone pillars of an ancient, flooded temple, casting an ethereal glow across the murky water. Umm, the air's heavy with the scent of damp stone and algae, and it's totally still down here. The water's near-freezing, but the pressure's not extreme - it feels more like I'm just beneath the surface. A massive, crystalline lens at the temple's core appears to be refracting light from a nonexistent sun that's somehow positioned below us, casting an inverted shadow of the temple on the seafloor above.
