Born on Yavin IV, Ki Din Was just an infant when the first death star was destroyed. He enlisted to fight the empire but was rejected many times for being too young. He traveled much after trying to find a master to train under. As a backup carrier he was apprenticing to fly transport ships and in a highly unlikely turn of events his ship was boarded and kidnapped by pirates.
Ki Din was first trained by a wayward orphan and Dark Jedi Rai Render, son of Dash Render who died in the Galactic Civil War. Rai had been a pupil of Luke's for a short time before going rouge. He pirated ships using bluffs and Jedi mind tricks to subdue many of his opponents. In his attempts to claim more Jedi Holicrons he found Ki Din, recognized his strength with the force, and thought it was time for him to train an apprentice for an ally.
After only a Couple years of training Ki Din refused the teachings of the dark side and demanded to be released. Rai allowed him leave but swore that Ki Din still owed him for sparing his life.
Ki Din went back home then to find that a Jedi Academy had been formed on his home planet and he then trained under Master Skywalker and Master Katarn.
When he faced the last of his Jedi Trials, the trial of flesh was on the ice planet Hoth. Ki Din found the pain of the cold almost intoxicating and decided to stay to help form a new temple there. He is now on the Hoth council with Master Rolland Jadeonar.
