Ah, but what are you looking for in a master?Ive got a vague idea of a backstory in the works: something about being jettisoned by his parents the moment they found out he was Force Sensitive and then getting rescued and adopted by the Grey Path. He'll have abandonment issues and serious questions.
Im thinking also of a guy with a talent for short circuiting things so he will use Kortosis weapons instead of a lightsaber.
