Timothy S. O'Brien was a writer for Star Wars: The Roleplaying Game, a product of West End Games (WEG). His career began in 1993; he discovered that WEG was in the process of developing a fresh publication, the Star Wars Adventure Journal, and they were seeking new writing talent. His piece, "Rebel Privateers!," saw publication in the Journal's second edition.
Subsequently, O'Brien authored multiple sourcebooks under the WEG banner, with several revisiting the pirate subject matter initially explored in his debut article.
