Deep Rot
A computer made out of the undead at the whim of a mad lich. It originated when someone on /tg/ realized that since undead skeletons and zombies could be given simple commands (e.g. Attack anyone that enters this room except myself), they could be ordered to respond to the actions of other skeletons and zombies (If one of those two skeletons raises their hand, raise yours, but not if they both raise their hands).
