Journey into the Void — Margaret Weis; Tracy Hickman

After centuries, pure evil finally has the power -- and the armies -- to prevail ...

Dagnarus has risen from the Void, backed by an unstoppable horde of bestial minions and a host of the insidious undead. Mortal kingdom after mortal kingdom must ultimately fall, as traitors wait to crown the dread lord behind the city gates of New Vinnengael. In this time of fear and chaos, the brutal conquest of all Loerem is at hand. Yet hope still flickers dimly in the impossible: in an unlikely hero's courageous venture into the Void's terrible darkness ... and in the reuniting of the long-sundered Sovereign Stone.
