The following account was recorded in the agent's log during your transmission: Uh, sunlight's cutting through a series of massive, crystal-encrusted stalactites in what appears to be a colossal cave system, Echo. Water's pouring in from every direction, creating a network of turbulent waterfalls that somehow feed into this calm, serene lake I'm seeing, and it's filled with... fossilized fish, their skeletal bodies frozen mid-swim. The air's thick and heavy with moisture, and I can smell the sweetness of wet stone, Echo. This whole cave system is somehow suspended high above a seemingly endless expanse of rust-red sand dunes, stretching out to the horizon.
