Build a underwater guardian base in...

Build a underwater guardian base inspired by ancient ocean monuments. The structure should feel like a lost, powerful civilization designed to harness ocean energy. Use layered prismarine blocks with glowing cores, water channels, and symmetrical but slightly worn architecture. The base should include a central energy core surrounded by guardian spawning chambers, with water flowing through the structure like veins. Add vertical pillars, arches, and domes to create a grand underwater temple feel. Incorporate glowing blocks to contrast the deep ocean darkness, and include signs of age such as cracks, missing sections, and coral overgrowth. The structure should feel both functional and ancient, with a mix of clean geometry and natural ocean decay.
