The Ser is the foundation for all creation. From it, the universe was created. It flows through and sustains the universe. It holds immense power. And the Seran have the ability to harness it. Generations ago, the Seran discovered the five attunements of the Ser, creating the five factions. From the ashes of the war that followed, the first Ambassador rose up to lead the Seran Empire into an era of tenuous peace. They took to the stars, expanding the Empire and making new discoveries. Later, a new war began against a new foreign race: the mysterious Nephta. Set against this backdrop, Shay'y of Ieoll, son of the Keeper of the Ambassadorial Court's Great Library, seeks vengeance on the ones responsible for his father's death. But when his impulsive actions force him to abandon his quest, he seeks to discover secrets that his father held onto until the day he died. As he uncovers the mysteries within both the Ambassadorial Court and the Guild of Overseers, one thing seems certain: there is more to his father's death than he thought.
