Left on her own for as long as she can remember, Rayla has learned to stay alive without relying on others. Her best friend, Raiden, has provided the only source of friendship in her life, and even he is kept at a distance. But when Raiden's life is threatened, Rayla finds herself giving everything she has to save him. Unfortunately, that means uncovering a deep power that lies within her lost lineage. This new power has attracted several enemies to the kingdom, and before they know it, Rayla and Raiden find themselves fighting for more than just their own lives. As they, along with new friends, are whisked away on a seemingly trivial journey, they quickly find themselves facing more than they've bargained for. And Rayla finds herself forced to face the past that she has tried so hard to forget.

Rayla has never known her family, nor where she comes from. For the first part of her life, she was forced to live on the streets of her home province in the kingdom of Rathús. It was there that she met her only friend, Raiden. The two grew closer together over time, although Rayla's past has left the girl with the natural instinct to remain independent. When the province's swordmaster sees Rayla defending herself from several troublesome boys one day, he enrolls her as the kingdom's first female battle student. Since then, Rayla has been training with the hopes of one day becoming a province guard, while her best friend Raiden is trained by one of the few remaining bowmasters in the kingdom. Soon, however, their lives are changed when Raiden is attacked by a man who claims that Rayla has special powers that could be a danger to the kingdom. When Rayla is forced to risk everything to save her friend, the two discover that she is the holder of a legendary magical power that lies within her lost bloodline. This power has attracted a particular enemy to the kingdom, and Rayla and Raiden find themselves, along with several new friends, on a race to discover just how much danger they are all in. Through all of this, Rayla is forced to face the question of where she comes from, and how she became the holder of her powers.
