When Myriad created Duniva he endowed his people children with different human virtues powers, each with its own strength and weakeness, in the hope they would complement each other and collaborate, creating a dynamic and prosperous society. Each virtue power is contained within a magical ring belonging to one of eight countriesled by Myriad's children and their descendants. But it didn't quite work out like that. Rivalries developed. Enmities grew out of them and the eight countries went to war. Having fought themselves into an endless and ruinous stalemate and finding the cost of war too high, a solution is proposed. Each of the eight countries will send their greatest warriors, known as sentinels, to a single combat tournament. The winner will take possession of all the rings and become the supreme ruler of Duniva.
The story opens with a strong action scene in which the Karvan sentinel is defeated by the seemingly invincible Titus Tyrannis, the Black Eagle and sentinel of Ankovia. With the Gold Lion dead, Kayeer is forced to step up as sentinel and take on his destiny. The action flows thick and fast after that, as the single combat tournament is organised and each bout is fought to the bitter end.
