To the common world, Aurora Falon is merely the pampered daughter of a rich and influential family. But to the secret world of The Order, she is Luna, the powerful and formidable warrior knight, under the rule of her master, Cole Iver. Together, they strive to bring down Damon Lexus, a wicked master who uses her knights in cowardly and dishonourable ways for her own selfish desires. But when they obtain evidence that may bring Damon Lexus under the judgement of The Order's ruling power, The Hand Council, Damon makes a rash decision and orders the assassination of Cole Iver.
By pure coincidence, Luna catches Damon’s knight in the act but is too late to save her master and kills the assassin in a moment of grief stricken rage. Luna knows the one with her master’s blood on her hands is not the one she killed, she seeks the assassin's master. But after a failed attempt at revenge, Luna is pulled from the depths of her dark anger and put on a better path by the Hunter who was ordered to kill her. Together, they will work to break away from being mere tools for the powerful and become heroes.
