Celtisa Vorn

Hey everyone, I'm new to SoNE and wanted to join the rebels; if I did could my sig-fig be a mercenary or bounty hunter working for the rebellion? Akin to Han Solo in episode V not being a rebel but working with them. Just would like to know as I build my characters background. Also if I did this I'm not saying my character would be boba fett or the like more on the Kyle Katarn mercenary type in dark forces 1. Thanks and I look forward to building soon.
