The following account was recorded in the agent's log during your transmission: Dark turquoise water pools within a colossal, naturally-formed cenote, illuminated by slivers of pale sunlight piercing through the thin, cavernous ceiling above, casting an ethereal glow. Uh, the air feels charged with ozone and smells kinda metallic, while the sound of distant, pulsating machinery echoes softly off the walls. Crystalline formations are somehow... pushing up through the water's surface, infusing it with a bioluminescent sheen, like the fungal networks beneath were somehow 'hacking' the fluid itself to harness energy. Water appears to be flowing up the sides of the cavern, refilling the cenote from some unseen source.
