“The Tower of Duma lies just ahead. It would be wise to approach with caution.”
—Halcyon talking to Celica
Halcyon is a non-playable character in Fire Emblem Gaiden.
Originally the High Priest of the Duma Faithful, he lost his position to Jedah after they had a dispute and escaped to Sage Hamlet in defeat. Known as the Great Sage of Duma, he lived at the edge of the village. During the game, he reveals that Mila is actually sealed within the Falchion, which is located beneath Duma Tower. Celica asks Halcyon if he can possibly help Alm. Halcyon unlocks Alm's potential, allowing him to promote to the Hero class whenever he wished from that point onward.
- Initially, Halcyon shared his portrait with Nomah. In the manga, he was given a shaven chin with a long mustache, and in Echoes: Shadows of Valentia, he was given gray hair and a small gray beard.
- While Halcyon never appears in gameplay, he is referred to as Sage in both versions of the game. In the remake, Echoes: Shadows of Valentia, Halcyon wears clothing identical to the uniform of the Sage class.
