You and I begin our in-game lives as normal, unassuming participants in the established civilizations, simply because that is our only option. We were, basically, born into the group of refugees. We begin our in-game lives as a part of everything the Marauders fight against, as part of everything they do not trust. We begin the game as a member of the group of people who abandoned them and their ancestors to the Kitin armies, perhaps leaving them behind to make our own escape a tiny bit easier.
There is little for us to do to prove ourselves to our native civilization; it takes slightly more work for us to prove ourselves to any of the other civilizations. It takes the most amount of work to prove ourselves to all of the civilizations, but we are still considered as "one of them" .
The work involved to really become accepted by the Marauder tribes, and not just have a fancy title that we can get right now should be comparable to changing your alignment from one faction to another (Kara to Kami, or vice versa).
You must first renounce your "alignment" with your current faction. You become neutral, but you are still hated by your intended faction, and must work to gain their acceptance and then their trust. I have recently worked Lagoon Brothers fame from -67 to -20 or so; it's a slow process that only speeds up once you get past a few hurdles; for me, it involved a lot of missions accepted while invulnerable that ended in my death. For the civs, you have very few options below the negative rating. That symbolizes the fact that it's a long process to gain the trust of your target faction after having aligned yourself with their enemies.
Once you DO align with your new target faction, any residual positive fame from your old faction is wiped out, and they instantly hate you.
