Once when Edward was a younger man, a young Graham and Malvolio were playing bat and ball behind the castle in the carrot patch. They accidently hit a ball over the wall and struck the king on the head. He came outside to the garden to discuss it with them, to which Graham was honest, and told the king it was his fault. From that day forward he had respect for Graham, and suggested he become a knight.
During Graham's wedding to Valanice in Caldaur's Castle, the ghost of Edward appeared to wish the king a long marriage.
Behind the scenes
Edward wears different clothing through the fan games, see Edward's Wardrobe (unofficial).
One fan theory is that the Wanderer may be King Edward and Priscilla was his first wife that later died when the famine struck Daventry, and after he gave away the Magic Shield in order to try save her. However King's Quest companion says that King Edward's wife was Queen Maylie. It gives Priscilla's husband's name as Kenneth the Huge.
