In a post-apocalyptic fantasy world setting, a catastrophic magical event wiped out much of the world's population. This event led to the birth of Nomads, or those who are born with magical powers. Practicing magic was swiftly banned by the surviving Kingdom of Humanity who viewed magic as being evil and the cause of the apocalypse. The persecution of Nomads became widespread and our hero, Orpheus, is among the few that remain. He has been thrown into the depths below where he must find freedom.
