Was thinking Bella and Cassandra (and maybe Alexander and Mortimer?) as spell-casters, considering lady Ravendancer goth and the goth's portrayal as magic users in that makin' magic image
I liked reading the idea of making Judith Ward into a spell-caster (perhaps an untamed one?), because I actually had plans to make her into a vampire instead, but the former occult state I think fits with her narrative more, perhaps some or most of her wealth - and maybe even her successes as an actor - comes from magic, and maybe some of those people she threw under the bus were fellow mages. This gives me another idea, in this one save of mine Octavia Moon died "mysteriously" (drowned/froze to death in the pool) and Thorne (after leaving/abandoning his son with the Hecking household) married Zoe Patel and started a new family with her (making them the Bailey-Patel family). Perhaps Judith resurrects and uses a perhaps vengeful Octavia to ruin her neighbor's career/fame, thus making her unrivaled somehow? idk, but it's a cool idea nonetheless.
I'm not sure who else I'd make into a spell-caster aside from one of Salim Benali's children when they're older, and maybe even Maaike Haas to sorta complement(?) her vampire roommate or something.
