Tides of Blood — Richard A. Knaak

As the War of Souls engulfs Ansalon, the minotaur empire and its ogre allies invade the stricken elven kingdom of Silvanesti. But blinded by his military successes, the minotaur Emperor Hotak ignores ominous signs of trouble within his realm.

And from the savage mining camps of the ogres rises an escaped minotaur slave with no ambitions of his own, save survival, a scion of the imperial bloodline whose course of action will push the empire to the brink of anarchy . . . and with it the rest of Krynn.
