This is a massive dark gothic fantasy floating castle built from dark gray and black stone, hovering high above golden clouds. The intricate cathedral-style architecture features towering spires, pointed arches, and flying buttresses. Vibrant purple magical energy glows from the windows and edges, giving it a mystical and ominous feel. Multiple floating islands are connected by stone bridges, with a tall central tower dominating the structure.
