I dont think he is a Sith or a Jedi! he seems like an Wanderer! Dude he is a Wanderer of The Force! feels like he got kicked out or chose to leave wtver Order he was in and now just does what he feels like!(probably Good heroic stuff....)
I'm leaning toword Jedi but if he is then he is one of the less common(except during kights of the old republic era) "Gray Jedi" that oftain flirted closly with the darkside. Some would use lightning,infiltrate enemy ranks, and commonly disagreed with the Jedi councle like Reven. Your Jedi looks kind of like Ulic Qel Droma. I really like the guantlets you gave him. Keep up the good work.
