Byron is a character from Fire Emblem: Genealogy of the Holy War. He is the Duke of Chalphy and commander of the Gruenen Ritter in the First Generation of the game, and the father of Sigurd and Ethlyn. He is a close adviser of Prince Kurth, and is often counseled by King Mananan of Isaach. Byron joins Prince Kurth during the Isaachian-Grannvaleian War, but when Prince Kurth is assassinated, he is blamed for said death by Lords Reptor and Lombard. In Chapter 5, he appears as an NPC unit, managing to evade arrest after suffering heavy injuries. With the last of his strength, Byron manages to bestow the Tyrfing sword on Sigurd before succumbing to his injuries.
