Rise of the Fallen Mage

In the Empire, Edmond holds the post of Supreme Archmage. He puts down a crisis of magical beasts, and afterwards he falls victim to a conspiracy. He crashes into the Shadow Wasteland and comes out of it with neither his memory nor his magic. An orphan girl named Lily saves his life there, and under the name Cole he survives alongside her. Twenty years later he is working as a stable slave for the Octavius family. He offends the young master, Sebastian, by accident, and after that the bullying and humiliation from Sebastian do not stop. Sebastian has spent years searching for his father. He finds that Cole carries a family badge that his mother made, and that the stable slave is that father.
