Magic Knight has been sent to the Castle of Spriteland by the King of Ibsisima in order to find a special present for Princess Germintrude. If Magic Knight is successful in his quest, he may have proved himself worthy of joining the famous "Polygon Table", a reference to the mythical Round Table from the legends of King Arthur.
