This is a traditional sword and sorcery Western fantasy backstory.
In the long past, when gods and demons still existed, the twelve God Lords and the Dragon Ancestors worked together to defeat the Demon King at the cost of their lives. However, before his death, the Demon King used his last magic power to launch a curse and declare that he would come back to the world again.
