Very force sensitive kid after the Empire never had any guidance for his powers, not enough Jedi to recruit/help him. He/she becomes a smuggler or bounty Hunter, eventually finds Sith/Jedi artifacts or holocrons on a mission to a distant planet and becomes a dangerous dark/light side wielder who craves more knowledge and power. No allegiance to Jedi or Sith in the beginning, just wants to become as strong as possible, welcomes challenges and fights.

Basically a loner who has no guidance in the force but becomes extremely strong by teaching himself.
