King's Quest III: To Heir Is Human

King Graham and Queen Valanice had two children, Alexander and Rosella, and the kingdom was once peaceful. It wasn't long until Alexander was snatched from his crib and things started to take a turn for the worse. A three-headed dragon threatens the ever-peaceful Daventry, and requires a maiden to be sacrificed every year. Rosella is the chosen one.

Meanwhile, in a secluded house atop a mountain in the land of Llewdor, the evil wizard called Manannan keeps a young lad named Gwydion as his slave, forcing him to do menial tasks as he prepares his spells and observes the country through his telescope. Gwydion must find a way to outsmart the wizard, escape, and eventually discover the truth about his own identity.

There are more items to collect in this installment, and more complex actions required to execute, raising the difficulty level. A large part of the game proceeds in real time, with Manannan following his own schedule, forcing the player to plan and time their actions. There is also a time limit imposed on the game's first major quest.
