She is a witch that resides in the town of Greendale, located on the opposite side of the Sweetwater River from Riverdale.
Early life
When she was sixteen, Zelda signed the Book of the Beast, pledging her allegiance to the Dark Lord and joined the Academy of Unseen Arts. When Hilda went to Academy, Zelda submitted her to the school's Harrowing, a form of hazing for new witches, making academic life difficult for her little sister.
When Sabrina was three days old, Zelda acted as a witness for her brother, Edward, in signing Sabrina's name to the Book of the Beast, promising Sabrina to the Dark Lord's service.
At some point, Zelda's nephew Ambrose was arrested for a conspiracy to blow up the Vatican, and when he refused to give up his co-conspirators, he was sentenced to house arrest under the watch of Hilda and Zelda. After Edward and Diana Spellman died, Zelda and her sister became Sabrina's guardians and raised her.
Physical Appearance
Zelda is a middle-aged woman with red hair and green eyes. Her clothing style reflects the fashion of the old Hollywood. She often wears elegant necklaces, fur, and sunglasses. She can regularly be seen with her cigarette holder. Her makeup often includes pink lipstick and black mascara.
Personality
Zelda is a stern, proud and sometimes haughty witch, devout to the Church of Night. She follows the rules of the Church but is also willing to break them, to protect her family. Although she often abuses and kills Hilda, Zelda genuinely loves and cares about her; one of her greatest fears is losing her forever. Despite her devotion to the Dark Lord and the Church, Zelda has standards about certain things and even took Father Blackwood's daughter away because she was afraid that he might harm her because the baby was not a male heir. Zelda is willing to always do the right thing, proven when - despite her aversion to mortals - she and her family, summoned a tornado to lure them all to Baxter High to protect them from the Red Angel of Death. Zelda is also the one who comforted Sabrina the best after her breakup with Harvey Kinkle, showing that she's also able to be emphatic and maternal to her niece.
