7 people are born in a world of supernatural powers known as Eion. The world is divided by two side, humans (the light side) and the demons or orcs(the dark side). They've been at war since the beginning, but there was a time when the war was supposed to end and a new friendship amongst the two sides were about to happen. But the dark side betrayed them and killed the strongest man(the first guardian). Now his child has returned to do what he couldn't do.
