Background
Barradua had barely joined up for 6 months by the end of the clone wars, but still has vivid memories of fighting alongside the Jedi and Clones. In his very first engagement he froze against the onslaught of Droids, and was nearly dead before a Twi'lek Jedi jumped in front of him and 2 droids had just suddenly been sliced in half.
Though he did not understand it, Barradua was appalled and confused st what happened at the end of the Clone Wars, but he stayed to do his duty. His comrades in arms and the clones he fought with turned into different people within the year, and it wasn't long till Barradua turned into an outcast. He attempted to save everyone he could, and was mocked mercilessly for providing medical aid to the poor and vulnerable.
Soon thereafter Barradua left and moved away from the capital and inner rim, finding work amongst the mid and outer rim colonies once more. For a time he worked as doctor, but monotonous work was not for him.
Barradua spent just under a year working as a mercenary in the outer rim, but he slowly got sick of the meaningless work, seeing too many people dead for petty grudges or only money.
When the opportunity came to join the rebellion, Barradua jumped at the chance to once more lead from the front, protect his comrades, and attempt to build a better world.
