Build a very spooky 200x200 Minecra...

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. Surround the mine with sagging witch-house facades, leaning chimneys, broken docks and murky swamp pools. Put a giant hollow dead tree north of the mine, with a house in its trunk and two sinister green eye windows. Keep roots, water, vines and mushrooms beyond the walkway. Palette: dark oak, spruce, mossy cobblestone, mossy stone bricks, deepslate, dark prismarine, green stained glass, cobwebs and soul lanterns. Use charcoal, rotten brown and sickly green; keep player flooring dry.
