Gareth

Gareth is a non-playable character in Fire Emblem: Path of Radiance, and an enemy/playable character in Fire Emblem: Radiant Dawn. He is a member of the Red Dragon tribe of Goldoa, and body guard to King Dheginsea or any royal retainers in need of personal guard (as seen when he stayed near Prince Kurthnaga in their first appearance). He is notably wider-set than your average Red Dragon, and, upon transformation, he is bigger and of a darker hue than most Red Dragons (or any dragon, for that matter).

Gareth is a loyal member of the Goldoan Royal Court. Although it is not clearly mentioned, he is a high-ranking member of the court and a retainer to both his King and Prince Kurthnaga.
