The following account was recorded in the agent's log during your transmission: Uh, I'm looking at an upside-down, half-submerged cathedral made entirely of coral and what appears to be fossils of ancient, extinct sea creatures, rising from the seafloor in the center of a crystal-clear lake. Thousands of thin, iridescent filaments stretch out from its facade, suspended motionless in the still, cold water like... a web of delicate fibers. The air above the lake is perfectly silent, with no ripples disturbing the glassy surface, and a soft, diffused light emanates from within the cathedral's core, illuminating schools of tiny, rainbow-colored fish that are seemingly trapped within its walls. The sun's invisible, hidden below the horizon.
