The Adrestian Empire is one of the three nations of the continent of Fódlan in Fire Emblem: Three Houses. At the start of the game, their emperor is Ionius von Hresvelg IX and the princess is Edelgard von Hresvelg. The students in the Black Eagles all hail from the Adrestian Empire, with the exception of Petra, who hails from Brigid but is affiliated with the empire through vassalage.
