All of Witch World knows to fear the hated, fire-eyed Keplian horses who lure riders to their deaths. All that is, save for one young Native American girl new to Witch World, who rescues a Keplian mare and her foal and discovers an awesome truth—the Keplians were created to serve light, not darkness, and to ride with humans. This is the first in a new trilogy.

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....

It is a desperate time in Witch World. The Magestone, the key to the pandimensional gates, has been lost and now all the gates are open. In the classic series' grand finale, an infinite flood of evil is about to wash across the world as Simon Tregarth returns to lead the planet's heroes in the final war against the forces of darkness.
