“We Sacaeans pray to the Sky and the Earth. The light of day and the darkness of night that engulfs this land... They produce wind, lightning, fire, ice, and many other affinities... Every person on this planet is protected by one of the elements. According to my clan's beliefs, I am protected by the Anima affinity.”
—Dayan to Yoder, in a support conversation
He's the leader of the Sacaen Kutolah tribe, to which Rath and Guy belong, and also the father of Rath from Fire Emblem: The Blazing Blade and the grandfather of Sue from Fire Emblem: The Binding Blade. He sends Sin to the other side of the continent to look for Sue.
Leader of the Liberation Army, he tries to free Sacae from the double threat of Bern soldiers and Sacaen traitors; he cannot hold back his enemies and despite the elimination of his clan, proceeds to weaken them by guerrilla actions.

Dayan has good bases and great weapon ranks. Dayan's main selling point, however, is that he joins right before chapter 21, and he is one of the few units who can reliably one-round the powerful Wyvern Lords with a Silver Bow, and pretty much the only one who can do so without any investment. His 20 Speed allows him to reliably double most enemies at base. Less notable, but still worth mentioning is his base C rank in swords, which allows him to wield things such as Steel swords, Wyrmslayers (very useful during enemy phase of Chapters 21 and 23) and Killing Edges at base, so he isn't stuck to 2 range if need be.
Dayan's only real issue is the fact that he and Juno cannot be used at the same time. Both are incredible ferry bots, and both are 8 movement units. The main difference is Dayan has good combat while Juno has flier utility. It comes down to preference of Sin/Sue vs. Shanna/Thea for which one you'll get and preference on which route you'd like to go. Both are extremely useful units in their own rights though.

- "Dayan built a new clan centering around his remaining Kutolah brothers. His quest did not go without oppression, but he used his perseverance and leadership to create harmony and lead the clan to become the greatest in Sacae."
“I can...hear the wind in the meadow once more...”
Dayan's name is most likely a reference to Dayan Khan, a descendant of Kublai Khan who ended Oirat domination over Mongolia and reunited the Mongols under the Northern Yuan dynasty.
- The "Choose Your Legends" event of Fire Emblem Heroes revealed that he was 755th place out of 791, making him the lowest scoring character of the Binding Blade portion with 39 votes.
- In the game's code, there is a version of Dayan that has S rank bows, which would mean he could have used Mulagir at base. Why this is not in the final version is unknown.
