— Death Knight

The Impregnable Fortress (Japanese: 鉄壁の要塞 Iron-walled fortress) is the twentieth chapter of Fire Emblem: Three Houses in the Azure Moon route.

Plot

Main article: The Impregnable Fortress (Azure Moon)/Script

As the Faerghus and Leicester forces consolidate, Dimitri declares that the group's next objective is to seize Fort Merceus, the last great hurdle between them and Enbarr, from the Death Knight. If the group discovered the Death Knight's true identity, Mercedes laments their upcoming conflict with her half-brother, but resolves to fight for what she believes in. Adrestia and Faerghus engage in battle, the Kingdom conquers Fort Merceus, and the Death Knight is slain; if his identity was discovered, he dies in a heartbroken Mercedes' arms. A soldier delivers a missive from Margrave Gautier revealing that order has been restored to Faerghus and that Kingdom reinforcements are on the way, and also reveals that a man claiming to have been involved in the Tragedy of Duscur was arrested.

Strategy

Main article: The Impregnable Fortress (Azure Moon)/Taking Fort Merceus

You received Failnaught at the end of the previous chapter. This weapon works best on Felix, Yuri, or Anna; of the other Crest-bearing archers, Bernadetta primarily uses bows for Encloser utility while Mercedes and Hanneman have magic-oriented stat spreads.
