Long May He Reign

Medieval Nonmagic AU: Hermione, the advisor of Crown Prince Harry, was sent by King Regent Dumbeldore to negotiate a peace treaty with the neighboring kingdom ruled by Voldemort. Dumbledore has her hunting for secrets within the Little Hangleton Castle, and these are the "soul" of Voldemort's operation. But he neglected to mention that she also had to marry the mad king. Oops.
