He is Bartz's father and raised Bartz alone after the death of his wife, Stella. According to Bartz, Dorgann kept many secrets from his son. After Stella's death, they moved around until Dorgann fell terminally ill and died three years prior to the game's main storyline. His final wishes were to be buried next to his wife and for Bartz to explore the world.
Later, it is revealed that Dorgann was a member of the Warriors of Dawn, who had sealed Exdeath thirty years ago. Dorgann opted to remain on Bartz's world to watch Exdeath's seal while the other three Warriors returned to their world. Along with the other three warriors, Dorgann appears at the end of the game to give the new generation of Warriors the strength to fight and destroy Exdeath once and for all.
