From publisher blurb: The world of Exodus boasts a turbulent history—from the rise of the Kaga to the defeat of the First Ones and the events of the Twilight War, from the creation of the Imperial Alliance to the present crisis that threatens to tear the Alliance apart. But even in this world, there are mysteries, and the greatest one in all of the world of Exodus is Xao. Xao: Island of Iron and Silk is an island that is a homage to the lost cities and continents of Atlantis, Avalon, Lemuria, and Mu combined with the Chinese / Indian / Southeast Asian inspired themes, mythology and background in the NeoExodus campaign setting. This sourcebook is a small overview of Xao and it five major locations.
