Role in the Series
Grimtrix first appears in "Hexley Hall" when Cedric and Princess Sofia arrive at Hexley Hall. When Grimtrix asks them why they're there, Cedric tells him that they're there so Sofia can do some research for her Alchemy Class at Royal Prep. Later on, he reveals that he has known that their reason for being there is to research the Amulet of Avalor due to having been watching them through his Crystal Ball since they arrived and that he wants the Amulet so he can take over a kingdom. He then tries to snatch the Amulet from Sofia with his Crystal Ball. However, Sofia turns the tables on him and destroys his Crystal Ball by using the Amulet to turn herself into a bulldog. She and Cedric then escape.
