The Sith expansionary campaign was the name given to a series of aggressive actions made by the Sith Order of Decreto during the early 230’s ABY. The Dark Lord of the Decreton Empire at the time; Darth Wyyrlok, having been criticized by many of the Sith Knights that he ruled, had decided that in order to keep the Decreton Empire in power over the galaxy, they needed to expand beyond its borders. There they found something they were not expecting at all. A race of technologically-advanced Humans who were undaunted by the colossal Sith warships that faced them.
