The following account was recorded in the agent's log during your transmission: Water pours down through this hollowed-out, crystalline cave system, sunlight diffused through the crystal structures above casting no shadows on the walls. Air's pretty cool and still, with this super faint, acrid smell like sulfur or something... A massive, mechanical orrery hangs from the center of the cave, somehow still perfectly functioning, the intricate brass components whirring as it tracks the movements of, like, impossible celestial bodies. The orrery appears to be centered around a gleaming, silver sigil representing the 'Black Sun' from the mythology of the Order of the Temple of the Rosy Cross.
