Eliwod Fire Emblem: Rekka no Ken Images

Eliwood (エリウッド Eriuddo) appears as one of the three main characters in Fire Emblem: Rekka no Ken, and is the father of Roy (Fire Emblem), the main character of Fire Emblem: Fūin no Tsurugi.

Eliwood was born of the noble house of Pherae, his father was Lord Elbert and his mother was Lady Eleanora. His childhood best friend was Hector the younger brother of the Marquess Ostia. These two attended school together and as they grew older their friendship grew as well.

In Lyn's tale, by chance one day when Eliwood was scheduled to meet with Hector he stumbled upon a group of bandits who had captured a young girl named Ninian. After he set about rescuing the girl he met Lyn and decided to see if he could help her in her quest to free Caelin from Lord Lundgren. Eliwood convinced Caelin's neighbors to remain neutral in Lyn's dispute.

In Eliwood's tale, Eliwood is a noble on a quest to find his father, who had been kidnapped by the Dark Druid, Nergal. His objectives soon change, however, and Eliwood fights a group of assassins called the Black Fang. As the story progresses, Eliwood comes to battle with Nergal's morphs (zombie-like creatures, some of who are sentient), Nergal himself, and a renegade Fire Dragon to save the world. To defeat Nergal, he journeys deep within the earth to retrieve Durandal, a legendary sword and the eponymous Rekka no Ken or "Blazing Sword", which was used by Roland, the founder of Lycia.

Depending on his supports, he can wed Lyndis, Ninian, or Fiora, and becomes the father of Roy.

In Fūin no Tsurugi, he is beset by illness, so he decides to stay at Castle Pherae to not be a burden on Roy, he then sends his son to Ostia and hired Dieck's mercenaries to help him.
