Sabrina Spellman, is really a half-witch (her mother is a “mortal”, while her father was a warlock) lives with her two aunts, Hilda and Zelda (both witches themselves), in the fictional town of Greendale, which is located somewhere near Riverdale, the home of Archie Andrews. Also living with the three women as the family pet is Salem Saberhagen, a warlock-turned-cat for constant world domination activities.
Most of Sabrina’s adventures consist of Sabrina either trying to use her powers in secret to help others (witches generally are not allowed to tell mortals about their abilities), learning more about her powers (either through her aunts or from trips to the “Other Realm”, an extradimensional plane that is the home of various magical creatures, including witches), or trying to deal with the day-to-day trials of being a teenager. Sabrina also has a mortal boyfriend named Harvey Kinkle, who like nearly all the other mortals in Sabrina’s world, is unaware his girlfriend is a witch.
