Game: Kings Quest: Quest for the Crown (Enhanced VGA)

The Kingdom of Daventry is in serious trouble, after its precious magical items have been stolen from Castle Daventry. King Edward the Benevolent lacked an heir. A sorcerer promised to help the queen bear an heir, if they gave him their mirror that tells the future; looking in the mirror, the king and queen saw a vision of a young man becoming king. Thinking it was their own future son, they gave the mirror to the evil sorcerer. Alas, it was a lie and she had no heir. Years later, as the queen was sick and dying, a dwarf showed up promising to give a plant's root that would cure her illness, if only the king would give him the "shield that protects its wearer against danger". The king agreed. The dwarf gave the plant's root to the king, and departed. However the dwarf had lied to the king, and the queen fared worse and died. Sometime later the king looked for a new queen. One day, he rescued a beautiful young Princess Dahlia from the land of Cumberland. However, on the night of their wedding, she was discovered to be really an evil witch, and she stole the "chest that is always filled with gold" from the treasure and flew out of the castle on her broom. In time, the castle fell into ruin. Knowing that he had to save the kingdom, King Edward sends his bravest knight, Sir Graham, to retrieve the lost treasures. Because he had no heir, if Graham should succeed, he would become the next king.
