Background
Vooz Muglin is a hard-boiled duros investigative journalist who has run afoul of the Empire after exposing a prominent Coruscanti official's connections to an undercity crime lord. The ramifications for the story went far beyond his expectations, with his HoloPamphlet dropping him under Imperial pressure, and earning him enemies both Imperial and criminal. In the two years since the story he's been lying low, selling his skills as more of a private detective, or freelancing as a journalist for smaller, radical publications. He used to care about ideals, like truth and democracy. These days he's most often concerned with day-to-day survival, but his bitterness has gradually fermented into a drive for vengeance. Vooz dresses to blend into the crowd and takes in all of the information he can. You never know when you'll hear some valuable information, and a low-key watchful eye pays his bills.
Motivation
Vengeance against the Empire for ruining his career
Somewhere hidden deep inside of him might be some remaining idealism, for truth and knowledge.
