Mrs. Crumlin is Max's guardian who isn't a very good baker. She works for the High Eclehon & spied on Max's Gran. She tricked Max into believing that he was allergic to sun particles and  took all the books that were in his room, except for Owls of the Wild, which was hidden in his closet along with a shell his Gran gave him. She also took his toy owl, which angered Max. Rose insults her by calling her "Crumpet." She is stated to have many wrinkles in her face & sausage-shaped fingers. She might have been married, since she goes by Mrs. Crumlin instead of Miss Crumlin.
