Sacrifice

Sacrifice in the context of King's Quest generally refers to the topic of human sacrifice/virgin sacrifice (or at least sacrificing members of ones own species).

Background
King Graham is known for having sacrificed many virigin maidens of his kingdom to the Three-Headed Dragon... Some say on the advice of his prime minister, as well as the demands of the dragon itself. He even attempted to sacrifice his own daughter Rosella when his kingdom ran out of maidens to sacrifice. She was rescued at the last moment by her long lost brother Alexander.

The Winged Ones were close to mastering the secrets of the catacombs some years ago, when a minotaur taking an instant liking to the dark funereal place, decided to take up residence. At first, the Kingdom attempted to regain the hostage artifact, but, between the dangers of the catacombs itself and the minotaur`s stealth and treachery, the losses became too grave to continue the struggle and the minotaur was left to his prize. Since then, the catacombs have been bolted shut. It is one of the great sorrows of the kingdom that each year the minotaur demands, and must be given, the living sacrifice of his choice lest he emerge from the catacombs and attack the city.
