This is a mega map dungeon, 60x80 (6000x8000px / 100px grid) that works with the Fortress or Ruin set. It is broken and aged, with winding halls, and oddly shaped rooms. There are ancient tombs and a well that leads down to oblivion. It should work as a stand alone dungeon that has been overtaken by any subterranean creature or even some undead. Cheers!
