Barris Offee

Barris Offee is the former apprentice of Jedi Knight Luminara Unduli, exiled from the original Jedi Order for acts of terrorism. She is now a trusted member of the New Jedi Order, and President Dooku's right hand.

History
After joining the New Jedi Order, she found her old master Luminara attempting to end Dooku's life. Her journey to the Dark Side was completed by foiling this assassination, killing her and getting Dooku medical aid to save his life, if not his hand or eye.

She swiftly became one of his favored agents, both in the field and in an advisory role. Over the course of the next three years, she hunts down and kills several rogue Jedi and convincing others to join the New Jedi Order. Eventually she found Ahsoka Tano, and appealed to their old friendship. Now that Tano was equally jaded with the old Order, as well as having seen that the galaxy had actually remained pretty stable under Separatist rule after all, she reluctantly agreed to join.
