Sophic as an information gatherer, forger, black market supplier would probably fit inside most PC stories at some point, since she helps people who don't want to be found get lost. She also provides things the Empire doesn't want people to have to precisely those people the Empire wouldn't want to have them. For smuggler types she can put together a very nice 'end user' certificate, a very nice 'bill of sale', a very nice ship registration.
Sophic would fit into an Andor-like game well, being the back room counterpart to someone like Luthen. She's a survivor of a desperate fight that turned into a lost war, in which her side was betrayed by their former allies, The anti CIS Republic. Given this she's a good match for Aelyx's post..
Aelyx
She'd fit best in a story of desperation punctuated with grand (even if ultimately futile) acts of defiance, in the vein of Andor.
Sophic would also fit well into a Firefly style group, being pretty much hopeless in several areas and so would match the sentiment expressed in Renlo's post.
Renlo
Renlo isn't the Main Character, and while he could be a supporting character, he's really designed as a character for a story where all the characters have their moment to shine. His best fit would likely be in a Firefly-type story - a story focused on the crew of a single ship, taking on what work they can so they can keep flying.
Though there's nothing stopping Aelyx's game and Renlo's game being one and the same, since Aelyx's post is about mood, while Renlo's is more about the situation and the group dynamic.
Jor'dan
Personality wise, there's a lot of overlap between Sophic and Jor'dan. They're both soldiers (though he might consider her an armed civilian), both war weary, both carrying around a fair bit of inverted snobbery, both pretty much orphaned by the war and looking for new people.
Bambi
Bambi, skills wise, is clearly everything Sophic is not, in practically a 'you complete me' fashion. They share a criminal underhanded 'they'll come at you sideways' vibe. Someone has to build Luthen's toys.
Eksy
Well Sophic and Eksy constitute a droid and a droid builder/repairer, both hardware and software, so there's that. They're not really on the same wavelength personality wise, since Sophic's not into revenge, just into fighting, winning and hopefully not dying. On the other hand, differently motivated individuals often see the same opportunities to do some damage.
Darion
Darion's a smuggler who helps out planetary communities in trouble. Lots of overlap there. Sophic's a criminal. Darion's a criminal.
Not seeing overlap or there's not enough current detail to say whether she'd group up with...
Mathias
Kishatriya
Zaffo
Zin'dak
Trrihuunchyyywl.. can't think of a reason why she would associate with someone who dislikes everyone. :(
