A cheerful, earthy witch who lives in the heart of Lancre town, surrounded by a sprawling family of children, grandchildren, and cowed daughters-in-law. She has been married three times, has fifteen children, and rules her domestic empire with warm, iron authority. Nanny is practical, sociable, and fond of drink, and she frequently sings a bawdy song about hedgehogs. She keeps an enormous, battle-scarred tomcat called Greebo and serves as the comfortable middle ground between Granny Weatherwax's severity and Magrat's idealism.
