The following account was recorded in the agent's log during your transmission: Dark, turbulent water churns through a series of ancient, stepped canals set into a sprawling, cyclopean aqueduct system, its weathered stones somehow infused with tiny, pulsing nodules of bioluminescent fungi. Umm, the air's heavy with the scent of wet stone and there's a low, constant hum, like the aqueduct itself is resonating with the vibrations of some distant engine. A partially-submerged, pale quartz crystal formation at the canal's edge seems to be... casting a shadow that's behaving according to a different set of spatial geometry rules than everything else.
