Set in ancient Persia, it begins outside the castle of the young King Xerxes, who inherited a magical golden chalice from his father, Darius the Great. Coveted by Greek foes King Leonidas of Sparta and King Minos of Crete, the chalice has been stolen.
Your quest is to seek and return the royal chalice to its pedestal within the castle of Xerxes...a stealth mission to preclude open hostilities. But, there will be obstacles to overcome. You must find the keys to various realms, defend yourself against dragons and the Minotaur, avoid snakes and pesky bats who steal things only to drop them in random locations, and survive the maze of the green mamba and carnivorous beetles.
