I haven't read Magneto's solo series, nor do I really particularly want to (Magneto just isn't a character I'm willing to plop down cash to read about on a solo basis), but I'd really like to have some context for Briar Raleigh, since she's in the new Hellfire Club.

Who is this person? Why is she aligned with Magneto? And why do so many posters on this board think she hung the moon? I'm not trying to be sarcastic, but I'd genuinely like to know so I can at least have an idea as to why she's in UXM.
