Well if he stays with the Felucians long enough, after three threads on Felucia (which we can time-skip over for Hrassk's sake), Lethe will find a ship that is part of his mysterious past and he can give Hrassk a ride off planet.
I've always thought it interesting the parallels Lucas managed to make between the SW Universe and reality. I like his inspirations too; like the Knights Templar and how they were eventually done away with. I remember reading about a similar "Knight/Warrior" type organization that was used personally I believe by one of the ancient Asian rulers and then they were wiped out too. Do you know what I'm talking about?
