A tall hexagonal tower, the central structure of an industrial city. Built from dark stone bricks, deepslate, and iron blocks. Red phosphor lighting: redstone lamps and red stained glass windows. Industrial details: metal pipes, chains, antennas, and a large glowing red core near the top. Weathered, post-apocalyptic. Footprint 20x20, height 60 blocks. Single building, no surroundings.
