Acheron is a character in Fire Emblem: Three Houses. He is a minor noble in the Leicester Alliance.


Acheron is the head of an unidentified noble house, the smallest in the Leicester Alliance, with territory just north of the Great Bridge of Myrddin. His political opportunism has earned him the moniker "the Weathervane", and is looked down upon by just about everyone, especially Count Gloucester's son, Lorenz

Despite the lack of power he holds, he still holds enough influence in both the Alliance and Empire that simply removing him would be unfeasible.
