Build a very spooky 200x200 Minecraft prison mine. Center an EXACT 25x25 clear mine opening, empty for a plugin; borders stay outside it. Keep it open to the sky. Add a continuous 6-block-wide flat, clear full-block walkway and level south entrance. Fence off scenery and seal facade doors. Build a colossal skull-shaped mausoleum north of the mine, with hollow black eye sockets, cracked cheeks, uneven teeth and a sealed mouth entrance. Surround it with gothic crypt facades, rib-like buttresses, broken spires, coffins and tilted gravestones. Palette: deepslate bricks and tiles, cracked polished blackstone bricks, bone blocks, calcite, iron bars, gray stained glass, chains, soul lanterns and jack o'lanterns. Keep masonry dark with pale skull reliefs and sparse cyan-lit burial niches.
