In order to secure a successful invasion of Fhirdiad, Edelgard launches a raid on the Fortress City of Arianrhod, which occupies a key position on the border.
At Arianrhod, a mage serving House Blaiddyd named Cornelia and the head of House Fraldarius, Rodrigue, strengthen their defenses.
Battle - The Siege of Arianrhod
With razor-sharp focus on the unification of Fódlan, Edelgard feigns a premature assault on Fhirdiad while the Black Eagle Strike Force instead descends on the southern stronghold of Arianrhod.
