Bana Breemu is an NPC, a Galactic Senator. Honest, well-meaning, but weak-willed and timid, she was presumably no longer with the Senate when it grew corrupt with power and was not onboard the Peace Moon when it blew up, wiping out the entire corrupt Senate.
Revelation of the Sith Edit
C-3PO and R2-D2 attended a meeting Padme was having with her fellow Senators, including Bail Organa, Mon Mothma, Chi Eekway Papanoida, and Bana Breemu. Padme suggested they overthrow the Senate, but her fellow Senators were all weak-willed and timid except for Bail Organa. Bana tried to sound assertive by declaring that she once ordered the slightly more expensive sandwiches for a meeting. Without permission. When Organa declared he was in favor of overthrowing the Senate, Bana exclaimed that he was her hero.
