King's Quest II (PC/DOS) 1985-87, Sierra On-Line

Having retrieved the three stolen treasures of Daventry, Sir Graham became the new king of Daventry. The mirror shows him a vision about a beautiful young woman, Valanice, in captivity on the top of an ivory crystal tower. Being charmed by her, King Graham travels to the world of Kolyma to rescue Valanice. There he must travel through sea, air, and even death to gain the keys that unlock the three doors to the enchanted island where the witch Hagatha has imprisoned Valanice. After meeting legendary figures such as Neptune, Little Red Riding Hood and Count Dracula, the latter of whom he kills, Graham rescues Valanice. At the end of the game, they are married in a ceremony attended by many of Graham's friends and several of his former enemies.
