“As something of an inventor myself, I have the utmost respect for our first king—and I love this country. But a coup d'état brought Niðavellir to ruin... I will do anything to save this country, so you have my support.”
—Eitri speaking with the Order of Heroes

Eitri is the true villain of Book V of Fire Emblem Heroes. She is the Seiðjárn Researcher of Niðavellir, and has long worked to further the progress of her country.


Eitri is a sage known for her hobbies of crafting and inventing using seiðjárn. Because her forest is well guarded by traps, few people, not even those from Niðavellir, tread there unless absolutely necessary.

After repelling her brother Ótr with the aid of the Order of Heroes, Reginn suggests finding Eitri to give them aid. As they enter her forest, Eitri's traps slow down the Order of Heroes, allowing Fáfnir to corner them. Despite their best efforts, Fáfnir's overwhelming power nearly wipes them all out until Eitri's timely appearance allows them to escape. Before leaving, she states her displeasure at Fáfnir's descent and vows to help the Order of Heroes stop him.

Once the Order of Heroes gains the assistance of Dagr and Nótt, Ótr goes to Eitri's sanctum, where she tries to replicate the Breidablik's power with seiðjárn to make the Járngreipr, a weapon able to destroy the portals between other worlds. When the Order of Heroes catch up to him, Eitri reveals that she intended on betraying them from the start. She attempts to summon heroes, but the summon was incomplete and the heroes' souls were destroyed. The Heroes then chase after and save Kiran, who she wanted to kill so she could use their soul to complete her weapon. However, the Heroes failed to defeat her and retreat. She then decides to use Fáfnir's love for conquest in order to force the Heroes to go after him. Her plan is to capture Kiran again while their allies are facing the King so she could complete Járngreipr.

Eventually after Fáfnir finds a copy of Breidablik during the conquest of Embla, he immediately heads back to her forest to confront Eitri of the truth. She quickly appears where she reveals that Fáfnir was also another one of her summoned experiments as a ploy to fix her nation. She also reveals Járngreipr was made just to make sure Ótr wouldn't lose him before she turns Gramr on the king and drags him to her realm.

Sometime after the deaths of Ótr, Fáfnir and Nótt, Eitri meets with Loki in her realm where the trickster tells her about how Fáfnir knew her plan. Eventually the Order of Heroes arrive in her realm now determined to kill her in order to prevent another Fáfnir incident. Eitri however uses her magic and skills to send more soldiers and further hide in her realm while also revealing to Reginn that she has lived way longer and even knew the first king of Niðavellir because of the fact she was able to use the power of a dragon to reincarnate when she dies. Eitri also mentions that Alfrik, Dvalinn, Billingr, and Grer were all versions of her making her the true Seiðjárn researcher. In the end, while she puts up a good fight against the order, Reginn unlocks the true power of Gramr and uses it to strike the final blow on the forest sage. Finally defeated, Eitri accepts her fate and that Reginn is the true ruler of Niðavellir before she crumbles to dust, something that Alfonse mentions that the full power of Gramr was too much for the mortal body to bare.

However just before her death, Eitri manages to record a video of herself talking to Kiran which the summoner acquires at the end of Book V. She tells the summoner how the two are no different from one another as they use heroes as pawns to fulfill their own desires. She ends the videos saying that while her future has been set, Kiran's is still clouded in mystery, stating they'll never expect what's coming next.

Beyond Control

Around the time while the Order of Heroes were still trapped in Dökkálfheimr, Eitri and Otr were still trying to figure out how to solve the problem of summoning Heroes without their souls. As a solution, Eitri attempts to summon Heroes who have already lost their souls which include fallen versions of Lilith, Ninian, Rhea and an alternate version of Gustav from a world where Hel won.

Despite her attempts to control them, the four quickly turn on Eitri and Otr with Ninian and Rhea turning into berserk dragons and Gustav personally attacking the two. Lilith meanwhile attempts to escape but she encounters Loki who offers her to return to Anankos if she were to steal Eitri's Breidablik for her. Just as Loki appears with Lilith and Eitri's about to user Grim Brokkr, beams of light suddenly appear causing the four heroes to vanish. When Otr wonders what happened, Loki says that the four were summoned by Kiran because the copy can't form contracts with the heroes. The combined forces of Kiran's Breidablik and Grim Brokkr also implies that it would take around a year for them to appear with no memory of first incident when they were summoned.

Eitri ultimately declares the experiment a failure but decides to continue their work. When she refuses to give Loki her Breidablik copy, Loki says that two copies of the weapon would be dangerous before leaving saying that she'll eventually come back for it. With the sorceress gone, Eitri tells Otr to hide her copy in Embla's Tower of Blood and sets her sights on Jötunheimr, foreshadowing the events of Book V.


Known for her skills in crafting and inventing, Eitri is very wise and cunning as she's able to create traps that makes her forest well guarded and come up with a variety of plans. She's also kind and considerate to those she allies with and is surprisingly calm even in the face of danger. These traits are however a clever ruse to her true nature.

Eitri is actually very manipulative, fooling Reginn and the Order of Heroes that she was on their side while plotting to steal the Breidablik in order to replicate its ability of being able to summon heroes for the realm.

Having lived 1,000 years through different bodies, she no longer sees value in human life, having no qualms with human experimentation when trying to master the art of summoning, even when the heroes' souls were destroyed. She sees this as a service to Niðavellir in honor of the first King, as well as using Fáfnir as a pawn to eliminate Ótr by transforming him into a dragon so that he too may be cut down. She even coldly states that the only way Reginn can see her brothers again is if Kiran summons newer versions of them from other worlds, showing how meaningless human life is to her. Another example of this is when she admits to Alfonse that she views people as playthings.

In spite of her views on human life, Eitri ultimately respects those who best her in both battle and her intelligence believing that the ones who defeat her will save the nation that she loves.

Base Set

Eitri serves as the final Legendary Hero of Book V and comes in as a Green Tome Flier unit with Pair Up Fire Blessing. For the most part, she packs an incredible 41 base Atk and a relatively good mixed bulk score of 67 physical and 68 magical. Her main downside is her middling Spd at base 29, not high enough to naturally double attack a host of units nor avoid beind doubled herself. As one can expect, Eitri is not lacking just because of her stats. Instead her kit contains several powerful tools that takes good advantage of her strengths while covering her weaknesses.
Grim Brokkr is Eitri's weapon that naturally gives her an additional Atk+3 to her base stats, giving her a high 57 Atk with her base Atk value. For the first four turns of battle, Eitri has a【Canto (2)】effect, allowing her to move two spaces after either attacking, destroying a structure, or using a assist skill on an ally, but cannot attack or use her assist skill again while under the Canto effect. As such, she can be a tremendously useful Aether Raids unit. In addition, if Eitri either initiates combat or is not adjacent to an ally, she inflicts an Atk/Res-6 debuff on her foe during combat and is given a guaranteed follow-up attack. This mainly gives her the opportunity to suppress enemies through sheer damage output and fixes the issue with her Spd when used to attack.
Divine Recreation is Eitri's unique Legendary Skill that inflicts a -4 debuff onto her foe during combat if they enter combat with at least 50% of their maximum health. This debuff does stack on Grim Brokkr's debuff, thus her foe suffers a massive Atk/Res-10 under both weapon's conditions. In addition, she also reduces the first attack she recieves during by 30%, which resets every new fight under the health conditions. The combination of both of these skills as a whole turns Eitri into a veritable fortress and a solid check to a ton of magical units in particular.
Dragon Fang boosts her already solid Atk by 50% when it activates for more pure damage. Attack Resistance Solo 4 gives Eitri Atk/Res+7 during combat if she is not adjacent to an ally. Finally Attack Resistance Rein inflicts Atk/Res-4 on foes within two spaces of her during combat.


Eitri's base kit is mainly focused on improving her Atk and Res thus physical units, especially the huge host of Sword can easily cut her down at close range, especially those with solid Spd or ways to obtain follow-up attacks as none of Eitri's base skills address her foe's ability to perform follow-up attacks. Commonly encountered sword foes like Legendary Sigurd, Reginn, and Brave Marth can easily tear her to shreds. An Iote's Shield-less Eitri has to also worry about Bow units as their effective damage also similarly decimate her. As such Claude and his various forms, Ascendant Laegjarn, Leif's two bow forms, and more can easily shoot her down.

Skill Inheritance

Eitri's only empty slot is her Assist skill in which Reposition is a great, cheap option due to her superior movement as a flier and can use this to position allies in a variety of ways. Moonbow is a better Special skill as it can further reduce her foe's Res which tends to have better returns than trying to boost her Atk. Glimmer can also be solid if she can obtain some buffs from her allies as well.

In Norse Mythology, Eitri the dwarf was the creator of the golden boar Gullinbursti, the golden ring Draupnir, and the hammer Mjölnir. He is also the brother of Brokkr.

Her alias, Dvalinn, is a dwarf from Norse Mythology who's name translates to "the dormant one" or "the one slumbering." He's listed as one of the Four Stags of Yggdrasil and is known for crafting Tyrfing and Brísingamen.

Her alias, Billingr, was the father of a maiden from Norse Mythology that Odin fell in love with once. The maiden told Odin to meet her at nightfall where she would marry him but when Odin returned, he found the place heavily guarded and a female dog tied to her bed in her place. The story is a reminder of the deception of women and the folly of unobtainable longing.

Her other two alias, Alfrik and Grer were two of the four dwarves who created Brísingamen alongside Dvalinn and Berling.
