King Horne is first seen in Horne Castle when Brandt presents himself to King Horne to become a man. King Horne and Carino ask Brandt to save Aire from the Witch's Mansion. When Brandt and the others defeat Louhi, all the citizens of Horne are turned into stone, but King Horne is nowhere to be found.
After being sent fifteen years into the past, the party goes to Horne and follow the King and the chancellor into the catacombs. There they find King Horne attempting to make a deal with Louhi to obtain the ultimate magic in exchange for Aire. After defeating Louhi again, the party finds out that King Horne was turned into a parrot by the demon Satan and the demon assuming his form. King Horne then ended up at Kuore's house and was named Ankhel.
The party returns to the catacombs and defeats Satan, returning Horne into his true form. Once normal, the King gives the party the Desolator Tome. King Horne is seen once again at the end of the game with the rest of the royal family, thanking the heroes for saving the world.
