The following account was recorded in the agent's log during your transmission: Uh, a sprawling, cyclopean aqueduct system stretches out, somehow woven from what looks like coral and black stone. The air's crisp and cool, smelling of seaweed and ozone, with the sound of rushing water echoing off the curved walls. Umm, a procession of massive, crystalline... 'eggs' are moving along the bottom of the aqueduct, each emitting a low hum, leaving behind trails of glittering, bioluminescent algae that seem to be somehow reacting to the sound of distant seismic tremors. A faint, turquoise glow is seeping through the walls themselves, casting no shadows.
