Umm, people being taken to the fort and never being seen again? Sounds like a-rate motivation to me. I don't like grinding for EP - that's a game breaker for me. I agree that, lore-wise, voidwoken should be attracted there. They are all over the place outside of Ft Joy. Perhaps Bracus has something to do with keeping them out. Much is unsaid and left to the imagination in these games. I've never killed allies or traders and have done fine. I don't even steal from neutrals. I've generally reached about level 20 and that seems to be enough (although I really made a mess of things my first two playthroughs). Basically, there is no need to grind in this game and that is a good thing. No-reason respawns really irk me anyway.
