For several centuries now, bloodthirsty demons have been hunting every night - forest, air, fire, stone, sand. Once people fought them on equal terms, but those days are long gone, and now the only fragile defense against evil spirits are magical symbols, whose origin is lost in myths. In addition, only a select few, masters from the guild of throwers, own the art of using these amulet symbols. On a ravaged, feral, war-torn Earth, saving ancient knowledge is kept under lock and key, while the supernatural power of demons grows stronger every night.
