The Ellfs of the Jeweled Isles had gathered to celebrate their prince's Majority Ritual when a strange fleet of oilskin boats landed on their shores. They brought a group of Celts called Firbolgs and the deformed gods they revered, the Fomorii. So long had it been since the Ellfs had known war that they were quickly overrun by the fierce invaders. Now, Prince Ellfstane and the Sorceress Katara must look into their people's forgotten memories to find a way to defend their isles from destruction. While Katara seeks a powerful weapon, Ellfstane discovers a spell to keep the kingdom away from the enemy's clawing hands. Together with the gods that sponsor their magical abilities, they craft a new home for their people in a place the Firbolgs would never expect.
