The Imperial Liberation Front (Imperil Ad Prioress Formam) (帝国解放戦線 Teikoku Kaihou Sensen?) is a terrorist group that secretly maneuvers through the Erebonian Empire. They are the main antagonists in The Legend of Heroes: Trails of Cold Steel. Under their slogan, they focalize on their main target, Chancellor Giliath Osbourne and his political party while large-scale daredevil incidents take place across the map. In their jet-black airship with mechanical robot weapons, this terrorist group appears to have many connections.
