White Council
The Red Court is highly organized in a feudalistic system with a King at the top, followed by Dukes and other ranks. The Red Court began a war against the White Council in response to Harry's actions in "Grave Peril", and the war is a long-running plot thread, continuing through subsequent books with the White Council on the defensive and struggling against the Red Court and their allies, while being assisted only by a few smaller allied organizations and limited help from the Faerie world in "Proven Guilty" as well as Changes".
