Use polished blackstone and deepslate as the main materials. Add amethyst and purple stained glass for energy core lighting. Include a vertical beacon beam from the center. Rings should be layered, symmetrical, and not made with random blocks. Add 8 simple arm-like extensions made of the same materials. Use sea lanterns for lighting. No terrain, no extra islands, no clutter—only the main structure, clean and detailed.
