One solid connected voxel island, Minecraft style. Flat round dark stone top, 36 blocks wide. Below it black rock tapering down to a long sharp point. On top: a ruined foundry with collapsed black basalt walls, two broken brick chimneys, rusted copper tanks, soot on the ground. Nothing at the edges. Colors: black basalt, dark grey, rust brown, green oxidized copper.
