There was once an Ancient Nomadic tribe who wandered the lands of Kanturu, part of their tribe was Notable hunter-warriors who hunted the skin and meat of the splinter wolves, the skin serves as their clothes and the horns were used as weapons. Going deep in the lands of Kanturu they encountered several beasts like the Genocider, Gigantis, Kentauros, Blade Hunters and one of which was a beast they called Berserk, this beast who destructively frenzied their warriors and hunters easily, no matter how many they sent out, their warriors were all killed by stronger beasts. Each day was a struggle for the Nomad Tribe and all hope was lost.

One day the Chieftain set out on a journey seeking stronger weapons, he wandered upon a strange place of relics there he met the Goddess Maya. He told Maya about the struggles they have, living with such stronger beasts in the lands of Kanturu and that He wanted to have something to defeat the beasts, Maya saw that the Chieftain's intentions were pure and his people in need of dire help. Thus Maya decided to give him the Power of the beast that they are fearing, and gave him the Berserker Scale Set.

Returning to his tribe the Chieftain fought the beasts and easily defeated them, he conquered most of the lands in Kanturu, but little did he know that the power of Nightmare was already spreading beyond control in Kanturu and that The Berserker Scale set will have effects on him whenever he uses it, The strength of the Berserker takes control over him, Enemy tribes would fear the Chieftain as no number of beasts nor man was enough to stop the Berserker Chieftain from killing anyone on its path.
