Guardians of the Lost: The Sovereign Stone Trilogy by Margaret Weis
The second volume in the Sovereign Stone trilogy, a gripping fantasy series filled with unique characters, from the authors of the bestselling DRAGONLANCE books
Generations after Vinnengael was laid to waste at the hands of Dagnarus, Gustav, the last human Dominion Lord, finally achieves his lifelong quest when he discovers the lost portion of the Sovereign Stone. Badly injured in a battle with one of Dagnarus's fearsome, otherworldly servants, Gustav entrusts the stone to young Bashae, without revealing its significance.
Bashae must make the long and dangerous journey to the Elven lands and deliver the jewel to a trusted friend of Gustav's, who will ensure it reaches the altar built for it in New Vinnengael. At all costs, the Stone must stay out of Dagnarus's hands. But hearing that it is in the possession of his enemies, Dagnarus unleashes war, hoping to seize the Stone in the conflict.
