The Battle of Dreven was the final confrontation within the Galactic Empire between Lorn Rhys and forces loyal to the apprehended Kendal Osbourne. With victory at Guritsan, Rhys set his forces upon the old Imperial throne world of Dreven, where resided many Imperial nobles and the last remnants of any organized force loyal to Osbourne. With the conclusion of the battle, Rhys remained unopposed and his hold on the throne was secured. He declared himself Emperor and made residence on Dreven's Castle Tsabak. From SW1ki, a Wikia wiki.
