From the back of the book:
The Dawnforge campaign setting offers you an opportunity to explore and shape a mythic age, and this player's companion gives you the tools to do so. Take advantage of the heritage and knowledge of your race with cultural feats like the Mark of Mordin, Dance of Blades and Vision of Glory. Learn new racial talents and transformations that give minotaurs the eye of the maze, teach night elves to drink the darkness, and imbue trueborn with the strenght of conquest. Play new races, from the determined ghost elves to the merciless forest wights, all striving to lead their people to glory.
Each region of the Dawnforg setting receives attention in these pages, and a new prestige class is presented for each race, tailored towards its niche in this legendary world. The Knights Adamant of the Kingsmarch defend the innocent, the fey travelers of the Sildanyr walk the paths between this world and Itheria, and tiefling diabolists summon powerful allies at terrible costs to their bodies and sould. Choose their paths, or one of your own. Prepare to make a name for yourself in the Age of Legend.
