So quick question for @Gowi should Magneto be accepted as he is:
For someone wanting to play Wanda or her kids, or potentially Pietro, what's the limit on doing that, since they basically don't exist in this universe? Would I be allowed to pretty much House of M that shit via alternate reality Wanda?
I just wanna prepare for the worst, 'cause I've been semi-planning on taking either Billy or Wanda to begin with. Wanda's gonna be involved regardless because finding out who his real mother is, then finding her is core to a lot of versions of Wiccan. This version would likely not be an exception, even if I change a lot of aspects of him. Anyway, I juggled the ideas between Daredevil and them before ultimately deciding on Matt and potentially bringing Billy or Wanda in later. Or when I have time, as I do in the coming days.
I really do not wanna use the Age of Ultron method for bring Wanda and Pietro in 'cause that's gross.
To quote my rules—
Legacies (NPCs, sidekicks, rogues) fall under the jurisdiction of the hero they are traditionally designed around. If you want to play The Joker, The Batman player has to be okay with it and your information should never contradict...
—we’ve got this pretty much covered. Essentially what this means is any offspring of Magneto is pretty much the Magneto player's territory and as long as it’s within reason what you say about it is the bottom line unless you go inactive. I would however keep all mentions and usages of alternate reality (and time-space in general) to a “probably not” due to the fact we’re still laying foundations here and going into that territory is very precocious.
