Down and Out:
Abandoned from a young age to survive in the depths of Corusant's underworld. This character starts out knowing that life is nasty, brutish, and short and probably has seen more than his share of horror. He may have seen friends and family members die from malnutrition, disease, or violence and witnessed tremendous injustice done to the weak or vulnerable. Despite (or because of) this harsh, early view of the universe, characters from this type of background strive to better themselves and do their utmost to escape their plight. The character either trains incessantly, picking up knowledge any way that he can, or simply is tough and resourceful enough to go out on his own.

I'm out for revenge and to get my money back... and to make the best damn mods/repairs in the fuckin' galaxy.

Betrayal:
I was betrayed by some smugglers after I did a job for them, and they stole my share of credits (€50,000).

Scavenger:
A Technician born and raised in the Outer Rim may have never seen a new machine fresh from the factory. He works strictly with second-hand stuff, some of it decades or even centuries old. The good ones can take old, broken-down machines and cobble together anything one could want, creating amazing, one-of-a-kind inventions that can never be replicated. Scavengers are always on the lookout for interesting new pieces of scrap to play with, and on the Outer Rim, there's always new scrap. There's also old scrap, sometimes very old scrap indeed, from civilizations long dead that could be extremely valuable to all the wrong people.
