Yeah, so like the Klan.
Seems like a good comparison. Both are pretty evil sons of bitches.
I like the idea, but Doc Velocity is a huge hole in it. If it was me, I'd have the group start somewhere else and have them focus on Khazan simply because it has a high metahuman population. That may make it more plausible.
It works either way really. Either as a terrorist cell from outside Khazan, or a hate group that just kind of pops up in the country. Either way, I think the Creed is a good place for a villain I've been thinking of...
