Re:Won't feature any main characters will be tough (Score 1)

Not really. There are enough story lines (such as the "tales" series - cantina, Jabba's palace and the back story on most of the bounty hunters that aren't main characters and the guild). Don't forget charaters brought up either in the books or in the comic series such as Prince Xizor, Kud'ar Mub'at, or Kuat. I don't think they call it the "Star Wars Universe" for nothing.
