The Royal Guard Division serves Quatre. From Captain Rashid on down, all members are former subjects of Winner who have pledged loyalty to Quatre and are fighting to restore the country. Though they lost their country, their trust and loyalty to their former king, Quatre, remained unwavering, and they continued to fight against Oswald of the Genesis Army until the very end.
The Maganac Corps, which had been escorting Quatre to Argus, also joined the Knights upon Quatre's return to the front lines.
