A Royal Affair

Four Kingdoms - Gryffindor, Hufflepuff, Ravenclaw, and Slytherin.

The Kingdom of Gryffindor rejoices when Crown Prince James of Gryffindor marries Princess Lily of the Kingdom of Ravenclaw. However, there are prophecies afoot, and after Lily dies in childbirth, an evil wizard makes a claim for their only child, Harry. Determined to keep his son safe, James gives his life willingly, and his parents, King Albus and Queen Minerva, resolve to fulfill Lily's dying wish: That Harry marry her childhood friend, Crown Prince Severus, of the Kingdom of Slytherin, to ensure that he is both loved and protected when others cannot do so anymore.
