Oath of the Dagger

No map available.





So...that grotesque creature was Edelgard... If she is prepared to transform her very body to fight for this future of hers... Then I have no choice but to defeat her, even if it costs me my life! We must defend the present... After all, it is all that we truly have.
— Dimitri

Oath of the Dagger is the twenty-second and final chapter of Fire Emblem: Three Houses in the Azure Moon route. It is not possible to return to Garreg Mach Monastery during this chapter; the previous chapter and this one must be completed consecutively.


Main article: Oath of the Dagger/Script

Dimitri and his forces storm the Imperial palace and face Edelgard in a climatic final battle. Her most elite forces and her newfound demonic power prove no match for Dimitri, and she is defeated and reverted to human form. Dimitri offers her hand in reconciliation one last time, but she throws his old dagger into his shoulder, forcing him to execute her. Afterwards, as narrated by Jeralt, Dimitri unites Fódlan under his prosperous rule as king of Faerghus. Rhea is rescued and retires from her role as Archbishop of the Church of Seiros, passing her role onto Byleth.

This is it, your final battle. If you've been saving anything like stat boosters or relic weapons for a rainy day, it's time to take out your umbrella. Hegemon Edelgard's 30 range and two moves per turn are a lot more terrifying on paper than in practice; she always targets Dimitri with one of her attacks, who can more than take it, she shoots like a drunk hillbilly, and she has an unfortunate tendency to three-shot your mages. Myson and his Bohr X spell and a Demonic Beast are on the right side, so the safest route to the throne room is up the left. It is worth noting, however, that killing Myson will cause those who slither in the dark to desert Edelgard on the spot. The three chests are a waste of time, as two measly points of Strength and Resistance and one measly Elixir probably aren't going to help you much with three quarters of a chapter to go.
