about 3000 years ago, a tribe was known for possessing a medallion that gave the wearer unlimited fighting skill by transforming that person into a beast. the problem was that the medallion made that person hunger for a fight even during peace time. it was to be used when other tribes would wage war at each other and with no one to match at the time, the medallion made the wearer look for a worthy opponent but was never satisfied. the last tribe warrior to wear it realized this and managed to remove it a hid it in a hole and buried it so no one would find it. but around the present day, archaeologist was able to find it along with other ancient artifacts. but a little interference with untamed supernatural power is likely to upset the balance of power among the gods
