Background
Istvan is a native from planet Navarion. He was a student of and old Force tradition, loosely related to the Jedi and exclusive to his planet.
In Navarion, management of the planets is charged to the Kulas, people similar to Senators, whose membership rotate every seven years between the different clans.
Clan Amonet, Istvan's clan, was in charge when Clan Nebtuu, a traditional rival, decided to execute a coup. Clan Nebtuu called in the CIS for help, which aided Clan Nebtuu oust the Amonets from power in exchange for exploitation of the planet's numerous natural resources. In the end, what happened is that the CIS took effective control of the planet for its own benefit.
Istvan's Master, on her dying moments, gave him the Amulet of Monithal, a ritual amulet given to adepts who pass their final tests (similar to Jedi's Lightsabers given on knighthood), and told him to escape, and that he wasn't ready yet to use his amulet but he would be in the future.
Istvan fled his home planet and joined the republican Army, where he was assigned to a small group of Jedi in the hopes that he finally unveils his Force powers and keeps the tradition.
Motivation
Preservation of his Force tradition
And
Liberation of his home planet.
Obligations

(I used Obligation as his starting career is from EotE, but it can very easily changed into any Duty if you so prefer).
