A stone wall. A stone wall is all that seperates two enemy tribes from eachother, the Air Tribe and the Fire Tribe. Hyunseung is a normal boy who lives in the Air Tribe. When he was growing up he was always told to never ever journey beyond the stone wall which seperated his home from brutal enemies. He had heard many rumours about the Fire Tribe and other tribes growing up, but he never put much thought into it until one day when he ventures far from his home, ending up at the old stone wall which no one, at least from his tribe, had ever gone out to before. Ever. Hyunseung is aware that he is breaking his tribe's rules by going out to the stone wall, but curiosity got the best of him and a boy whom he soon meets from the Fire Tribe named Junhyung.
