Survivor of Order 66 mainly due to a self imposed exile. Force sensitivity began to dim for unknown reasons and it was decided to best spend time in meditation away from the order to focus on regaining what was lost (and prevent further loss).
After learning of the destruction of the Jedi Order, Roken spends most of his time in hiding as a collector of rare and exotic artifacts. His saber is easily passed off as a black market trophy and his status as a collector/dealer has afforded him the ability to regain Jedi equipment in a secret effort to contact any remaining survivors. His Force impairment helps him avoid detection, but his ultimate goal is to regain full use of the force, find the remains of the order, and join them in the fight against the Sith.
Jedi costume is prequel style with some personalization, but leaning towards Obi-Wan.
