Patriotic Knight is the name given to a sidequest in Baten Kaitos: Eternal Wings and the Lost Ocean. The quest consists of showing the Diadem Royal Crest to one of the Knights of Diadem that has begun to lose his sense of purpose due to King Ladekahn being away in Anuenue for so long. Upon seeing the Crest, he is reminded of his duties as a Knight and his faith in the King is restored. This Knight can be found guarding the entrance to the grand hall in Castle Elnath, standing on the left side of the double doors. He will offer a Rainbow Ash as thanks, one of only two available in the game. This quest can be done any time after completing the Celestial Alps.
