Wraith, from Ultima I manual
|Only appearance:||Ultima I|
Wraith are the souls of dead clerics, returned to the world of the living by Mondain's magic. They act as his servants, attempting to turn others to evil in his name—that is, inducting them into their ranks through undeath. Wraiths have frightening stamina.
Summoned from the nethermost regions of Hell by Mondain's perverse enchantments, Wraiths are the restless souls of dead clerics. Once on the material plane, they drift about seeking potential converts to the discipline of Evil. Since one must first die in order to be converted, 'tis strongly advised that their enticements be resisted.
