If you're remembering the perky Halloweentown-esque "Other Realm" of the ABC sitcom, think again. Chilling Adventures hinges its mythology on Sabrina's "Dark Baptism," an induction into the witch community that serves the Dark Lord. No, not Voldemort — the literal Devil with a capital D. Sabrina's witchy rivals-turned-sometimes-allies, the Weird Sisters, openly enjoy inflicting torment on mortals, and Aunt Zelda regularly kills Aunt Hilda (who apparently can resurrect each time).
