The Blackthorne Oath

In the world of Aelthelmar, nearly everyone possesses aura, but few can fully awaken it or survive the dangerous trial to form a core and become masters. William Blackthorne is one of only twenty-five — a legendary warrior whose mastery of all five aura forms and the secret technique Void Requiem has made him both feared and revered. Called to the royal court of House Valerion, William must navigate the treacherous currents of politics, where alliances are forged as quickly as swords are drawn. When a royal engagement is arranged between him and Princess Elayne Valerion, William finds himself entangled in a web of power, ambition, and secrets that could change the balance of the realm. As whispers of rebellion stir and rival houses scheme, William must prove that mastery alone is not enough — cunning, strategy, and the unyielding will of the Obsidian Hand will be the only force capable of shaping the future. Action, intrigue, and a deadly aura system collide in this epic fantasy of war, loyalty, and the making of legends.
