Finn

Finn is a playable character from Fire Emblem: Genealogy of the Holy War and Fire Emblem: Thracia 776. He is a knight of Leonster who serves Quan during the events of the first generation. He is the only character in Genealogy of the Holy War who appears as a playable character in both Sigurd's and Seliph's tales.

He is 15 years old in the first generation of Genealogy of the Holy War and 34-35 years old in the second generation of Genealogy of the Holy War and Thracia 776.

While it is commonly believed that Nanna and Diarmuid may have different fathers (Finn and Beowolf respectively), it is stated in Fire Emblem's 20th Anniversary Book that her biological father is whoever the player married Lachesis to, and that Finn is more of her adoptive father. On the other hand, the pool of men that Lachesis can potentially marry in Genealogy does include Finn, and in Thracia 776 not only Nanna considers Finn her father, the game mechanics imply that she was not fathered by Beowulf (she cannot use the Beo Sword, unlike her brother Diarmuid and Beowulf's illegitimate son Fergus), so the matter remains muddled.
