The random effects, mostly. Not any real-world occult practice.
I was looking for, essentially, a "unified field theory" of Wanda's powers, something that would explain all the stuff she'd done in the past without contradicting them, as earlier explanations often did. She'd gone from "point and something bad happens" to "alter probability" to "reorder reality," and it seemed to me that everything she did was essentially chaotic and disruptive. So that, with the Chthon connection, suggested she was channeling and shaping some sort of chaotic force -- it would serve as an underlying explanation for all of that stuff.
And that would also let me essentially unify her powers -- rather than having a mutant power and magical skill, the mutant power could be to channel a particular flavor of magic, and the magical skill could help her in how she channels it. That way, instead of having two unrelated powers/skills that largely involve casting weird energy from her hands, she'd be using the power and the skill in tandem, wielding magic with her mutant power, shaping her mutant-channeled magic with her learned magic skills.
I thought it made her more coherent, less muddy in what she could do.
So when people talk about real-world occult beliefs, as if the idea is to reject all the stuff she did before and give her a new set of abilities, that's not what I meant at all. I wanted to embrace all the stuff she did before, and provide a context that united it.
Chthonic power, chaos magic, is (in my intent, at least) inherently disruptive and chaotic, and supports everything she'd been shown to do, whether it was the hex-spheres (chaos grenades), making bricks fly out of a fireplace to strike at someone (not probability-shifting because that's not probable at all, but still chaotic), to make a meteor veer out of its orbit (disruptive) to remaking reality (waaaay disruptive).
That was the intent. I thought it fit her very well, but it's been the subject of contradiction and reassertion since. Which is kind of chaotic itself, so maybe that fits.
I discussed it in a few posts recently, including:
