After an unexpected visit from a young Northman, Queen Siobhan learns that a terrible darkness has reared its foul head in the kingdom of Eirenoch. The minions of an ancient, evil spirit have stepped foot on her island and threaten to enslave its people. To save her lands, the queen must send her son, Prince Eamon, to the ruined temple of Dol Drakkar; a primordial shrine far to the north where the soul of the Dragon lies. There, Eamon will receive the blessing of the Firstborn and take on the mantle of all the kings before him. Only then can Eamon reawaken a long lost order of warriors known as the Knights of the Dragon, and lead the people of Eirenoch to victory.
