The Black Eagles house at the Officers Academy is comprised of students who hail from the Adrestian Empire. They favor the use of axes and black magic.
The twin-headed eagle of the Adrestian Empire's coat of arms and the black armor worn by Imperial soldiers inspired the name and banner of the Black Eagles.
- Edelgard von Hresvelg - The ambitious and determined heir apparent of the Adrestian Empire and the house leader of the Black Eagles.
- Hubert von Vestra - House Vestra's heir and Edelgard's devoted vassal since childhood. Cold and calculating at the surface, he conceals the honorable motives of his schemes and sinister countenance.
- Bernadetta von Varley - The shy and withdrawn daughter of Count Varley. Can usually be found holed up alone in her room when not attending class or battle.
- Caspar von Bergliez - A young son of House Bergliez who cannot expect an inheritance. A hotheaded student who prefers to act first, apologize later.
