No One's Witchcraft

Nathan was filled with a  burning ambition to take revenge on the empire. He felt something was different about him as his body felt light but invulnerable. He looked upon the lake and saw his new visage. 

He was no longer the scrawny and sickly boy. He was a young man with a chiseled body and he had a terrifying aura radiation from his body. 

Even the sword no longer had a silver shine. It was pitch black in color, he realized that this must have been due to the interference of the curse. 

He thought up his plan for revenge and finally set it into motion. 

The new cursed sword came with new powers, one very useful for his revenge. It granted him the power over the dead, he was now somewhat of a Necromancer . 

He started building an undead army, he started with the skeletons who he named Revenger1, Revenger2, Revenger3... Etc. He attacked the weakest vassal nations of the empire first, those with the lowest strength.
