Be a double agent.
The only thing you really have to do is start both processes... and perhaps give a little something to a certain gossipy barkeep...
Why be a double agent? Its a pretty stupid reason, but if you do both sides you get twice the exp...
Actually, there is justification for it because you can get an alliance between both factions. In the game world I'm not really sure how long it might last, but hey.
If I had to choose one though, I'd pick the Umpani just because the T'Rang look so dang weird... And, they sell Blunder Buss at their base, which is my favorite ranged weapon. [img]tongue.gif[/img]
