The Battle of Uffel was fought during the Osarian-Rhommamool conflict which occurred with the Yuuzhan Vong War (25–30 ABY). Uffel was a droid-manufacturing moon run, inhabited, and owned entirely by droids, whom settled the moon 90 BBY. Thus, this made it the target of the technophobic Red Knights of Life, an allied group of the Yuuzhan Vong invaders who hated any form of mechanical technology. However, the Red Knights were repelled by the Iron Knights.
