The fearsome Scarlet Knights of Genetic Purity have declared a campaign of terror against all mutants - humanoids and mutated animals!! Your bitter enemies, the Gray Rock tribe, have accused your tribe, the White Feathers, of murder and treachery. Your tribe is now under sentence of death - you and your party have been declared outlaws and traitors. The fate of your tribe lies in your hands. Pursued by an enraged mob of mutants, you must flee across the frozen Parklands of the Ancients to find proof of your innocence.
