The Sisters Grim were the delightfully named Agoniza and Eviscera Grim. They wrote/adapted fairy tales, and were probably the authors (or at least the compilers or editors) of the Grim Fairy Tales featured in Thief of Time. They were the aunts of Malicia Grim whose head they had filled with the improbable and wonderful. They more than certainly researched into Rural Myths, like those known to Lily Weatherwax and Black Aliss.
