Kaede was born 50 bby on the planet of Cato Neimoidia, his father was a well known politician named Nobunaga Bokugawa, as a family tradition Kaede followed in his father's footsteps and became a significant figure in neimoidian politics, he was also an able martial artist, showing good strength and prowess at a young age.
When he was in his late 20s he spoke out against how the separatists were going to sign his homeworld away to the banking clan, saying it was extremely offensive and inconsiderate to sign away a whole planet like a piece of property. He was quickly exiled by the separatist from separatist-controlled space. He then made his way to the republic centre of coruscnat, hoping to make a humble living as a merchant, though even then he never stopped practicing his martial arts. During his stay in coruscant he experienced abuse, verbal and physical, to himself and his shop, being a Neimoidian on the wrong side of the galaxy. This also brought the attention of the Jedi, whom he became friends with during their numerous visits to his shops (because of untrue rumours of infiltration and sabotage).
He in fact helped many of the Jedi when the empire outlawed them hiding many in his shop and using many of his trade contacts to arrange for transportation off world. This made him a Criminal, he escaped off world with a female Jedi named Jyne Utaka, whom he was very close friends with.
They went to the outer rim world of tatooine to escape imperial persecution. Jyne had also told him that though he didn't have the midichlorian count to use the force, he had the mind and body of a Jedi, and asked him if he wanted to be trained by her.
He accepted and in his years of training became adept in all martial arts and became as compitant as a Jedi. Then in 6 bby his 'master', was killed when her name was slipped into imperial hands, Kaede was out of town during this and was distraught when he returned to find his home and her shot and burned to the ground, he sought revenge and continued training in isolation until now.
•5 - exiled - Kaede was exiled from his home planet of Cato Neimoidia during the clone wars for speaking out against the separatists when they signed his homeworld away to the banking clan so they could buy more droid factories, something which he also didn't agree with. So he was exiled from separatist space.
•5 - criminal - Kaede, after the clone wars, lived on coruscant, during which he endured hardships no one could imagine, being a neimoidian on the wrong side of the conflict, but during which he saw Jedi first hand and their justice, he also met and became familiar with a lot of Jedi. And when the empire outlawed Jedi he helped them escape the empires hand, and as such became an outlaw.
