Esmerelda Weatherwax

Esmerelda "Esme" Weatherwax (also Granny Weatherwax or Mistress Weatherwax) is a fictional character from Terry Pratchett's Discworld series. She is a witch and member of the Lancre coven. She is the self-appointed guardian of her small country, and frequently defends it against supernatural powers. She is one of the Discworld series's main protagonists, having major roles in seven novels.

She is a very powerful witch, and is reckoned to be more powerful than the most well-known witch on the Discworld, Black Aliss. Granny says in Lords and Ladies that she "learned my craft from Nanny Gripes, who learned it from Goody Heggety, who got it from Nanna Plumb, who was taught it by Black Aliss". The witches of the Lancre coven reflect the roles of Maiden, Mother, and Crone, with Granny being most associated with the Crone (tactfully referred to as "the other one").
