Can I bother for some elaboration on the two factions in play? There's some things that are loosely implied but never really touched on so here's a (nonexhaustive) battery of questions that should apply to both:
[list][*]What kind of internal politics & ideologies exist?
[*]What does their endgame/win condition look like?
[*]What does the leadership structure look like in more detail?
[*]Are the deviant membership demographics incredibly binary or more nuanced?[/list]

One last question not related to the factions I want to hit you with and then I'll stop bothering you. Are powers, being genetically derived, limited to the capability of one's own body or can they extend beyond? Classic example: telekinesis, which extends well beyond the body of the individual.
