Undead unicorns are unicorns that have been brought back to life by a necromancer for the express purpose of doing evil. Their souls are inherently good, but they are forced to do evil by their master (the one who brought them back to life).
Undead Nature. An undead unicorn doesn't require air, food, drink, or sleep.
