According to impian lore and legends, the impian race has been doomed from the start. A special power was to be given to the last imp alive. Immortality, shape-shifting, and extreme resistance to pain were given to him. The one given the power of daemon was Hadediabla Crixus. He took the power and attempted to rule The World.
Most races do not believe in the power of daemon, however. They think it's tribal nonsense. Not even the very religious goblins think the power exists. Many elven scholars have researched the power and find no credible evidence that the power is real, and continue to call it blasphemy.
