The MagestoneAndre Norton, Mary H. Schaub
science fiction, fantasy
They are two strangers whose people have been at war for a millennium. Mereth, a Dales trader, crosses the sea to Estcarp and the archival citadel at Lormt, seeking clues to the fate of a missing heirloom, an ancient jewel of Power.
At the same time, an Alizonder hound lord, Kasarian, finds that an ancestor's key opens a magic gate to distant Lormt. Alizonders are wolfish tyrants who fight with sadistic poisons and feed fallen leaders to their dogs, but they have always abhorred the sorcery of Witch World.
Now, to Kasarian's horror, a maniacal baron seeks to unleash the dark wizards of Escore - using Mereth's long-lost Magestone, stolen from Kasarian's murdered father!
Two strangers, two foes suddenly share a common cause, and a legacy more dire than either could imagine.
