Underwater Dome Base
A sea base of glass domes on its own coral reef. A big central dome of glass panes on slim light ribs rises from a ring of stone bricks and deepslate with glowing windows over a lit glass shaft; inside, ring floors hold a prismarine heart circled by sea lanterns, a lounge, a library, galleys, coral planters and a spruce mezzanine up a stair. Four smaller domes, a coral garden, a bedroom, a kitchen and a workshop, stand apart on the reef in a star, each joined to the centre by a slim glass tunnel lit by sea lanterns. The reef is sand and gravel with clusters of coral trees, kelp and seagrass. Built from glass panes, prismarine, dark prismarine, sea lanterns, stone bricks, deepslate and coral blocks.
