"The Discovery of Magic," more commonly referred to as "the Magic Book," is a leather bound witches' tome filled with various information about magic and witchcraft. It was given to Edward Spellman (Sabrina's father) by Great-Granny in her will and was given to Sabrina as a present for her sixteenth birthday. The book also allows Sabrina to communicate with her father through his portrait, while he's away with the Other Realm Foreign Legion. It sometimes also works as a portal to certain places in the Other Realm. The Book can also be used to order certain magical items or to request the services of businessess from the Other Realm, which when called for will manifest through the book's pages.
