 While priests and wizards are traditionally at odds due to philosophical differences, neither Ridcully is of a particularly philosophical frame of mind, and they tend to ignore this.In "Lords and Ladies" we learn he had a relationship with a young Esme Weatherwax, some fifty years before becoming Archchancellor.It is suggested in the book that, in one of the many parallel universes adjacent to the one on which the Discworld novels take place, Ridcully and Esme Weatherwax are married and have children; though it also implies that they were all probably killed by the Queen of the Elves.
