Given the Nefantar only recently returned, their political stance, along with that of Starkmanir, is kind of uncertain.
If memory serves before the Day of Darkness the Nefantar where the leaders of the Matari. I would imagine they did a lot of the horse trading that got the Minmatar unified enough to get into space and start settling other worlds. That much is PF (I think).
Post invasion they got a reputation for sucking up to the Amarr in order to maintain their influence. When the revolt came they where largely tossed out along with their masters. The only way that
Empyrean Age makes sense at all is that a group within the tribe where really working to shield the rest of the people from the worst excesses of the empire and went underground within the empire to protect the last of the Starkmanir.
For the White Wolf original WoD players amongst you think of them as the small, resurgent, sane faction in the Silver Fangs. If this is true it would make them full on self-sacrificing heroic types. So of course they'll get shafted extra hard in the dystopian and then some setting of EVE.
Not so sure about the Starkmanir. However given they where game to try a one tribe revolt it could be they'd make the Brutor look downright calm and reasonable.
