I think a dungeon based upon the four horsemen of the apocalypse would be awesome. It could be a one-shot housing dungeon, like Baddle of the Bands or Tanglewood Terror, and we could fight the four horsemen separately. Maybe the horsemen have absorbed too much shadow, and once you fight one you gain it as a companion to fight the others? For example, let's say you fight Death first. You would then gain Death as a companion (like Ozzy) to fight the next, which could be Pestilence. Anyway, I think it would be super cool to just have the four horsemen in the game and maybe have them drop their armor and horse mounts (which shouldn't look like those short pony or stallion mounts).
