Dusk: A Crown Of Horns

What would you do if you were a child whose parents were on different sides of a bloody war between two worlds? If your very existence was despised, and men considered holy by the people wished you dead. You were placed in a camp and forced to suffer extreme hardships while watching the extermination of thousands of children just like you. What if you managed to escaped the camps but instead of the life of freedom you desired all you found was pain. Betrayed by someone you considered dear you were sold into bondage to worshipers of a demon king? They put you through intensive training and molded into an assassin to serve in the demon's army. But even then you were nothing more than a pawn to be discarded when your usefulness had expired. You were sent on a mission to assassinate a sorcerer from the other realm but were once again betrayed and left to die. But what if instead of death your intended victim offered to become your savior? You were given a choice to die alone in a strange world being nothing more than a victim yourself. Or you could obtain all the power you would need to bring Damnation to everyone who had wronged you... What would you do?
