A demonic nanny sent by Crowley to make sure that Warlock, whom Crowley believes is the Antichrist, gets a good dose of evil in his young life (even as Crowley has conspired with Aziraphale to make sure that Warlock also gets a solid dose of good in the form of the gardener Mr. Francis). Nanny Ashtoreth takes care of Warlock until he is six, and sings him satanic bedtime songs each night.
