A Summoner's inheritance is a power greater than magic. With rings of channeling, Summoners call forth demons and golems, supernatural servants and elemental creatures. Summoners have toppled empires and challenged gods. They are venerated as saviors and feared as destroyers. The chosen are born with a mark on one hand, but the origins of this gift were forgotten long ago. Joseph fears his power more than death itself. As a child, Joseph tried to save his village from attackers, but the demon he summoned slaughtered the villagers while Joseph watched in horror, his misguided heroics causing the deaths of those he loved. Exiled and ostracized, Joseph vowed never to summon again. Over the years, the enigmatic Yago counsels and guides the youth, preparing Joseph to fulfil his prophecy. As the invading armies of Orenia march across the Medevan plain, Yago urges Joseph to quest for the ancient rings. Reluctantly, Joseph agrees. On his journey, Joseph meets three young adventurers who become his companions-Flece, Jekhar, and Rosalind. Flece is a cunning thief and cynical rogue who grew up on the streets of Lenele. Jekhar's family perished when Joseph summoned a demon long ago, and now the warrior seeks revenge. Begrudgingly, he helps Joseph on his quest. Rosalind is novice of the Order of Iona and yearns to become a mage-priest and guardian of Iona's divine scrolls. The daughter of Yago, Rosalind is jealous of Joseph's power and hates her father for devoting his life to the Summoner’s cause. Their quest takes them across the world-to the sunken empire of Ikaemos and the rugged wilds of Liangshan, from the stronghold of the Khosani to the Jade River that flows from Heaven. In the ruins of lost civilizations and the temples of Orenia, they search for the Summoners' rings.
