From the introduction:
In the Wolf Wood, rival clans of wolfs and men war, each side seeking dominance and absolute power over the other. Between the two groups has long dwelled a tribe of xenophobic Westryn who see the werewolves as the purest incarnation of humankind. But the Elves must confront their own darkness and their own taint. Something twisted dwells within their hearts and spreads among them like a plague. Peshwah na Sulla calls upon you to travel with him into this land, and seek the fallen Arrows of Hadeen.
