" The Jewels of Anniera,” Nia said, “have been sought by Gnag the Nameless since the Great War fell on the shores of the Shining Isle and overcame it. Gnag destroyed all that was good and beautiful in that place…except for the jewels. And he has sought them ever since. He has obsessed over them and ruined nations in his search because he believes that the Jewels of Anniera hold a hidden power. His hunt for the jewels is what’s led him to Skree. If he didn’t believe they had come here, I don’t think he would have bothered crossing the Dark Sea of Darkness at all. "
