Sephiran

Sephiran is a non-playable character in Fire Emblem: Path of Radiance, and a boss/player character in Fire Emblem: Radiant Dawn as well as the main antagonist of the latter. He is the Prime Minister of the Begnion Empire, the most senior member of the Begnion Senate, and the Duke of Persis. He first appears in Path of Radiance in the guise of a pilgrim, although he is later shown to stop the Black Knight; the reason for the knight's obedience is not revealed until later in Radiant Dawn. In the final fight with Ashera, Sephiran bears only the Ashera Staff, forsaking his powerful personal tome, Creiddylad.
