ok, so, to the families thing, there isn't yet anything quite like that, save for a slowly forming branch of various governements that concerns itself with increasing Meta Human activity, and the possible consequences/implications of it, especially for how it will affect the world overall. (such as the formation of a dedicated prison facility and technology that can counter super-powers).

This universe isn't at the very beginning of superheroes as normal, but they're well into transition, still a lot of uncertainty, which is arguably the much more interesting time to operate in.

short answer: No factions exist... Yet
