Ryric was one of the original five Council Members. He joined Trivas, Nyne, and Draco before the Council was formed. The most unique thing about him was that he was a Grey Jedi, the only allowed within the ranks of the Sith until the Galaxial War. He was a very level headed, balanced man who offered many great ideas for the formation of the Sith. It was he who worked extensively with Trivas to form the original Code of Conduct.
In 39 ABY, Ryric started the Ryric Rebellion that resulted in the death of Draco and many others. In the end, Ryric was killed when his frigate was destroyed.
