Oliver

He is known as Duke Tanas, and is a senior member of the Begnion Senate who was believed to have been executed for crimes against the state following his defeat at the hands of the Greil Mercenaries in Chapter 17-4 of Fire Emblem: Path of Radiance. He was deeply involved in the Laguz slave trade prior to his defeat in Serenes Forest, having purchased Prince Reyson for an exorbitant fee from King Naesala of Kilvas as though he were but another art treasure for his vast collections. He can be used on Trial Maps after completing three playthroughs of the game.
