The struggle continues in Brotherhood of the Wolf. While heroic prince Gaborn managed to drive off the conqueror Raj Ahtan, Ahtan is far from defeated. Striking at far flung cities and fortresses, Ahtan seeks to draw out Gaborn, the Earth King, to crush him. But the armies of an ancient enemy issue forth from the very bowels of the earth. And unless Gaborn and Ahtan can look past their personal hatred and rivalry, all of humanity may perish.
