The following account was recorded in the agent's log during your transmission: Misty fog hangs low over a labyrinthine network of ancient, moss-covered brick tunnels somehow buried beneath the ice cap of one of Jupiter's moons. Umm, a low, steady hum of unclear origin seems to be emanating from the walls themselves, accompanied by the scent of damp earth and the faint tang of ozone. The air is heavy with the pressure of being so far beneath the ice, and like, tendrils of fog curl around ornate stone carvings depicting scenes of celestial battles, each image referencing various astral bodies not found in this solar system. The gravity here seems... inverted.
