On the Horun continent of Nebu, the slave named Sem had given up on life. The most notable thing that identified him as Horun had been taken away: his wings. However, when another slave named Raleema blames him for a tragedy that happens in the mine, he is forced into waging a war against Pharaoh Nizam XIII. For a decade, Nizam XIII had been abusing his power over the continent and the people of Nebu. His evil reign must be stopped at all costs. Can Sem and Raleema put aside their differences to stop Nizam XIII? Or will Nizam destroy the continent and the people of Nebu?
