Oh well that works with a lot of options actually:
Kat Kenrid: Falleen bounty hunter, mercenary, mandalorian. Don't expect elite mandalorian skills though, she was only freed by a mandalorian woman who trained her for a few years before she died. In respect of her Kat wears the armor and follows most of the womans rules. Now she's just trying to survive. Recently was discovered to be force sensitive and may retrieve training. She's good with people and likely to start up conversation. Could meet her on the job, or maybe her ship is having a problem (it's very old). She also might buy weapons from you if you have some good blasters.
Rocho Krul: Trandoshan bounty hunter. Technically an empirial knight for the Fel empire, though, since the faction thing I'm not sure they're coming back. So he's rich and really does this because he wants the points for the afterlife. He does have rules about who he kills and what he does, but it'd probably be considered wrong by a lot of other species. However he is reletively friendly and good with teams. He is probably pretty intimidating for most though, given trandoshans reputations, that he's like almost 6'11" I think, and is usually covered in ammo, a grenade launcherm, a double barrel shotgun, some armor, and carries a strange "cane" that is in fact a lightsaber axe. Because he's in a lot of fights it's possible his ship got damaged and he came down to have it fixed while searching for something and just end sup in conversation. Or just general meeting around cantinas and stuff. Unless you have weapons, which he might buy.
Mag: Well unless you're visiting a slavery land cantina you're unlikely to meet him. Real friendly, and buff, Zeltron man. Knows quite the number of languages for a non-droid and is good with people. He is, in fact, a dancer though he does sometimes double as essentially the bar muscle to throw people out or calm them down. Knows no life outside of slavery and really just goes with the flow.
Varian: A mandalorian. His job is actually essentially trading. He has a company driven by that. However which permits him to also move around a lot. He could also be met on the move during trade jobs, maybe even they are both middle men for some kind of deal. Although he also does occasionally fight for the sake of keeping his skills worthwhile, as well as just general training. So he can be taken a lot of places. He actually is very trained force sensitive, but in reverse as Rocho. Rocho has really specialized physical and sensory based powers, whereas Valerians are based in the mind. He doesn't use them often though around most people. He also has an adopted daughter NPC who comes with him now.
