Does your setting have a dark lord? A malevolent entity of malice and cruelty gathering the forces of evil to him from his throne while controlling the laws of nature and bending it to his will? An adversary that sets the plot in motion, unleashing perils and challenges for your heroes to overcome and the world will fall to eternal torment if you are to fail in overcoming him? What kind of realm does he inhabit? Who are his minions? Does he have goals? A tragic story?
