From the back cover:
On a rugged island filled with unnatural dangers, fierce and proud barbarians must fight for their lives.
The barbarians who call themselves the Knorr, driven from their homeland, wanted nothing but freedom and an honorable existence when they landed on the shores of Jakandor. What they found was an island occupied by despicable wielders of vile magic—the Broken People, as the Knorr call them, who rely on legions of animated corpses to do their fighting. These enemies represent everything the Knorr find hateful and dishonorable, and no clansman will rest until the last of the Broken People has tasted Knorrman steel.
