By the way, the ringleader witch could potentially be Actrise. Just, you know, not dressed all Victorian era-like because that wouldn't make any sense in CV3's time period. It actually fits pretty well when you consider how she spends the majority of CV64 trying to recruit Carrie due to her witch heritage.
I considered outright saying it was Actrise while I was writing it, but then I decided I was kitbashing canon enough as it is and just made her be Generic Immortal Gray-Haired Witch.
