Fae

Fae ​is a playable character in Fire Emblem: The Binding Blade. She is a Divine Dragon child from the hidden Manakete village of Arcadia. True to her appearance, she is childish and naïve. Despite this, she is several centuries old. Because she is a full blooded dragon, she ages very slowly, even more so than Sophia (who is a half-dragon). She always speaks in third person.

Fire Emblem: The Blazing Blade
Fae can be found in the house in Chapter 22 of Eliwood's story or Chapter 23 of Hector's story in Fire Emblem: The Blazing Blade, making a brief cameo. She is alone there watching the house. She reveals that there is treasure buried in the sand near the bones and implies that she encountered Pent, telling him about the treasure. Her name is only mentioned if Hawkeye enters the house, in which case, she will tease him about his habit of saying "Is that so?" and reveal information about the buried items.

Fire Emblem: The Binding Blade
When Roy first arrives in the hidden village, Fae wants to go with them but is forbidden to do so. Despite the guardians of Nabata watching over her, first Hawkeye, then his daughter Igrene, Fae sneaks out and is captured by Bern. She is saved by Roy later on and fights with the army using her Divinestone.
