An ancient prayer had been composed that can destroy Auril (the Rime/Rhyme of the Frostmaiden). It must be performed on her island to seal her for good. The pages of the poem were scattered and have found themselves in the possession of several power groups (the Bear Clan, the Dwarves, the Goblins, Bryn Shander, and the last is on Auril's island). The dead rider on the back of the white dragon can animate in the presence of the berserkers' brazier and tell them this information, because he was the original writer.
