I'll give you a bit of information that'll fix this whole thing.
She's um how do you put it? Um full of bullshit. All of those people are. They're full of bullshit. They know they're full of bullshit. When a few of them actually get in contact with each other and form a "circle" it's nothing more than a gaggle of retards trying to out bullshit each other.
In other words they're people who are so dull and boring they have to come up with something to make themselves seem/feel special.
I can assure you absolutely nothing at all is going to happen to you other than some mild verbal harassment. Creepy text messages once ever blue moon. Hollow threats and maybe if she's semi ballzy she'll leave some odd shit laying around wherever you move to to seal whatever bullshit curse she's "putting on you". It'll vary and be random as shit cause they can "create their own spells"and crap. Like a circle of bones (I've seen a dumb dumb actually use bones from takeout chicken wings he ate earlier)
My other suggestion is getting a security cam because if she does go full retard with her harassment it'll work in your favor to convince the judge to tell her to gtfo and quit her shenanigans or face some nasty contempt charges.
I have VAST experience with these people due to pre dope growing hobbies.
The shit I've seen/heard.
They're actually a morbid curiosity of mine and it's a huge guilty pleasure to get inside of their heads and figure out what makes them tick (and it ain't much).
And if that doesn't work then tell them you were contacted by -flip through the Dungeons and Dragons Monster Manual and go to the subsection known as fiends, find anything with a CR or hit dice (if old school) rating of 16 or above- and tell them you're a grand vizier or agent of that creature. You're now a glove of the left hand path and their souls will be forfeit should they continue pissing you off.
Fucking neopagans (they were called wiccans in the 90s and 20s, this title insults them now) make me want to punch babies.
