White quartz and calcite walls, dark slate roofs, elegant gothic towers, grand staircases, moon gardens, waterfalls, cherry blossom trees, glowing blue crystals, observatory. An ancient alien spaceship is buried beneath the castle. Only a giant circular engine ring and broken metallic hull are visible above ground.
