The Shaman's Totem

From the publisher:

"Green cannibals have invaded from the lands of the distant south, lead by their foul shaman and his shadow magic. They've taken an ancient dwarven stronghold in the mountains for their own, forsaking its history, holding up in its depths for the coming winter. The shaman, it is said, holds a powerful totem, a device of black magic that might be turned to good if a righteous challenger could seize it. The bold and the foolish take up arms, unable to resist the allure of the Shaman's Totem!"
