At the beginning of her career, Jenna Zan Arbor was a famed scientist and the head of Arbor Industries.
Zan Arbor was also known to help planets with little technology such as Melasaton overcome their burdens.
Zan Arbor felt she needed a subject stronger in the Force, so she captured Qui-Gon Jinn from Didi's Cafe and took him to her research facility on Simpla-12.
He was commander of a cavalry force and served on the northern and eastern frontiers of the Han Dynasty empire fighting against various non-Chinese peoples.
Gongsun Zan was known as the 'General of Baima' and renowned for his brigade of elite cavalry from Baima, made up completely of horses of pure white (Bai Ma means white horse in Chinese).
It seems he hit on the tactic of using all white horses in battle when he learned the barbarians he was then fighting against considered the animals sacred and would run from them instead of fighting.
