“Lester, if I were you I'd be a bit more concerned about your sister. Lana might be out here fighting for all you know.”
—Diarmuid in Fire Emblem: Genealogy of the Holy War

Diarmuid is a character from Fire Emblem: Genealogy of the Holy War and Fire Emblem: Thracia 776. He is the son of Lachesis and the older brother of Nanna, and is possibly the half-brother of Fergus.

In Genealogy of the Holy War, Diarmuid is a member of Seliph's army and trains alongside Oifey. In Thracia 776, he joins Leif's army to protect his sister. He is able to wield the Beo Sword in this game, hinting that his canon father is Beowolf.

His substitute character is Tristan in Genealogy of the Holy War.

Coming with the Charm skill, Diarmuid will always be able to support your other units, but if his father does not pass down the Pursuit skill, he will not be an ideal fighter.

Beowolf, Azelle, and Finn are considered to be the best fathers for Diarmuid, but he will do just fine as long as he inherits the Pursuit skill. Despite the fact that Azelle is of the Mage class, Diarmuid's Strength will not suffer any repercussions, as this is thankfully offset by Lachesis' Minor Hezul Holy Blood. Additionally, Azelle's Minor Fjalar Holy Blood will enable Diarmuid to be a formidable unit with any Magic Sword he wields.

Dew can make a good father, bestowing great Strength, other great growths, and good base stats. However he may not be able to pass down the Pursuit skill even if he is promoted. There would also not be much point to passing down the Bargain skill to Diarmuid because money should not be a problem for him. Alec can provide similar stats, but will not be as good.

Lex is another candidate who can make a good father, since Paragon makes many characters powerful in a short amount of time and Diarmuid joins early. If this is pursued then Diarmuid will have much of the same niche as Lex, having great strength and defense alongside an overall good speed stat. The biggest downsides is that Pursuit will not be passed down to him, and Lex does not wield swords, but these can be abated through the Pursuit Ring and having Lex kill enemies such as Chagall who do have swords that he can pass down to Diarmuid.

Midir can also make a good father, passing down the same skills as Beowolf and a better Speed growth. However Diarmuid's HP, Strength, Skill, and Luck will suffer, although the Strength loss will not matter much because he will most likely cap it anyway.


In Chapter 7, Oifey may speak to Diarmuid, and Diarmuid will gain one point of Strength, one point of Skill, and one point of Defense.

In Chapter 7, Diarmuid may speak to Nanna, and Nanna will gain one point of Luck.

Think of Diarmuid as a weaker, more support oriented version of Fergus. He has higher Movement, and stats almost comparable to Fergus at similar levels. Regardless of which, he still makes for a useful unit, with slightly above average stats for his level. However, as he joins Leif's army relatively late into the game, he will often be completely overlooked. He will end up being an above average fighter, and when coupled with the Beo Sword, will be capable of taking out quite a number of enemies on his own. Furthermore, he will be able to provide noticeable bonuses to other units within two spaces, further enhancing his usefulness as a unit on the battlefield.

  • There is a minor script error that occurs in Genealogy of the Holy War during the conversation between Oifey and Diarmuid in Chapter 7 if Finn is Diarmuid's father. While discussing Nanna, Diarmuid says "I heard she was with a knight of Leonster named Finn", implying that Diarmuid is unfamiliar with Finn or the fact that Finn is his father. Given that Lewyn explains Lachesis' actions following the Belhalla Massacre to Diarmuid, it seems odd that neither he nor Oifey (who knows Finn) would mention to Diarmuid that Finn was his father, particularly since they are both presumably aware that he is alive. It is safe to assume that this was simply overlooked.
