Seth

Seth is a playable character from Fire Emblem : The Sacred Stones. He is the second character the player can control, and is arguably one of the most powerful fighter among the early accessible characters - having a second generation, paladin, class right from the start of the game.

Story
Seth is General of the Knights of Renais, the elite cavalry force of the Renais Kingdom. Following the brutal invasion by the overwhelming forces of the Grado Empire, he - on Fado's orders - flees from the country in order to protect Princess Eirika, by conducting her to safety at the Frelia Kingdom.
