From the Publisher's Website:
The apelords, once savage apes living in the frozen forests of the North, were changed by the mists of the Shroud forever, giving them the minds of men. Now nomads, they wander the Shroud and beyond, their home forests overrun by the living dead.
Inside this PDF you’ll find a complete player race for Dungeons & Dragons Fourth Edition, along with six racial feats you can use to go ape. You’ll also find several monster entries, from the wandering nomads of the apelord tribes, their guardians and leaders, and the vile undead corruptions of their ancestors and fallen warriors (ranging from levels 4 to 9), and finishing out with a full page of adventure ideas for bringing the tribes of the ape into your game!
