HDRI, A circular chamber of polished obsidian, its walls curving inward to form a dome. At the center sits a massive throne carved from white stone, unadorned and simple, with no figure occupying it. The ground is perfectly reflective, so the throne appears doubled, suspended above an inverted world below. At the apex of the dome, a single point of light glows like a star, casting faint rays that do not reach the floor.
