The Sum Of All Men: Book 1 of the Runelords

In the first book of The Runelords, Raj Ahten, the Wolf Lord of Indhopal, uses magic to transform himself into the ultimate warrior: The Sum of All Men. He seeks to bring all of humanity under his rule - destroying anything and anyone in his path. Standing in his way is Prince Gaborn Val Orden, who must fulfil a 2,000-year-old prophecy and become the Earth King, a mythic figure who can unleash the forces of the earth itself. Only then will humanity have a chance to survive. . .
