From the Back Cover: A Call to Arms has been Issued! The center of the universe, Pnumadesi has been endangered many times throughout its history; from the splitting of the planes (and so too the continents), to the Second War of Elements and the return of the Xendauni. This player's companion offers information on how to incorporate the majority of Dungeons & Dragons races and classes into the world of Pnumadesi. It also provides backstory and information on how to play 3 new races (Ursaren, Vedros, and Xendauni), as well as two new classes (The Totemist and the Sentinel). Finally, enhance your games with new signature powers, backgrounds, feats, rituals and magic items, all of which provide flavor for the world, but can be used on any plane. On the plane in the middle of the cosmos, danger calls for the Children of Destiny.
