The Gryphon Stone

Of all the worlds in the multiverse, Adrathea is the last David Render would willingly revisit. What happened there broke his heart and drove him to retire from the UN Multiverse Survey. To hang up his sword forever. Then Treyvar of the Alvehn brings disturbing news. Adrathea is in peril, and David's old comrade needs his help to stop a rogue Alvehn from usurping the throne and ruling the planet forever as an immortal tyrant. To set things right, David must return to the one place he never wants to see again. But Adrathea is a world to which David's fate is bound by the most intimate of ties. He has no choice. Adrathea calls, and he must answer.
