Bal grew up in high society. He served in the Galactic Republic as a junior Senator's aid. That was until the Empire...
As an alien he did not advance in the Senate. He saw the injustice and powerlessness of the Senate. He witnessed how the Emperor siezed more and more power. He patiently waited and worked with Senators like Garm Bel'Iblis, Mon Mothma, and Bail Organa. As the flegling Rebellion grew so did his involvement. When Mon Mothma openly declared rebellion against the Empire Bal joined her in her fight. Now he is a full fledged member of the Rebellion working with a small unit ensuring that they are fully supported with the best starfighters.
