Background
Oz was a young man, not able to fight when his clan was wiped out during the Clan Wars on Mandalore. One of his uncles managed to get him and a few of his cousins out... but with no money, they had no options. His uncle died on a bad job and Oz found himself on the streets of Coruscant. With no other options, he signed up with Civil Enforcement.
Having already been trained to fight, he found the academy somewhat easy. Surprisingly he actually enjoyed police work. Standing in a line with his fellow officers, smashing the uppity mobs in the skull with his baton... It wasn't in Beskar against the enemies of his clan. But it wasn't that bad. Time moved on... the Clone Wars happened. The Empire rose. Oz just kept working at his job.
Until a hotshot Moff breezed into his Sector House and started running the place. Badly. Oz couldn't keep his fucking mouth shut forever and eventually mouthed off. Drawing the Moff's personal attention.
After it all went pear shaped, Oz found himself demoted and reassigned to one of the shittiest departments on the planet. The bastard even took his pension! Now he is an old man just trying to get by.
