A spoiled girl who gets everything she wants (Ariella Quinn Arceta) suddenly falls in love with Mikhaela Janna Jimenea Lim, without knowing what kind of darkness is hiding behind that girl.

With a single, decisive blow, Cassandra - Shadow of Sammos, immortal warrior, and general of the Thiria - ended the war. The Emperor is dead and the Empire has fallen. Now that she is faced with the weight of rebuilding the world, Cass is blindsided by the choices of people she's never met. A Council she's never heard of demands she deliver the Emperor's head to an enemy general across the vast desert nation of Desheret. With her is a wide array of travelers from every nation, including old friends and old enemies. Cass must learn how to solve problems without her strength, violence, or her army, and navigate a world that doesn't yet know the Emperor is dead.

Los pocos descendientes demoníacos que quedan son utilizados como sujetos de experimentación, con el fin de crear una nueva raza híbrida: más poderosa que cualquier héroe, y tan temible como los antiguos demonios.
