The conflict between the Northern Empire and the orc tribes living around Tartaros Highlands in the northwest began more than four hundred years ago. The enormous kingdom was never rid of the shadow of war ever since.
Although the orcs' civilizations were not developed and advanced, they were good in battles and wars. They were fearless against death and pain. With the encouragement of their shamans and the ancient spirits of their ancestors, any orc, even a minor female orc, could become a warrior. Their physiques were far more superior to the physique of any human being. Though those primitive creatures held bone sticks and rock-made spears, the human soldiers who wore excellent armor were actually disadvantaged.
