"If you bring them in to this they will have forces within the empire." The Rize archangel was sure that Genesis was telling him that they were already taking the side of the Fel empire.
"Why would you turn them away? They could be of help and you are not at war. Not to mention the fact that you will be invited to bring more light mages to their desert to help with undead. It just makes sense. The Fel empire has unique mages that can trap powerful wyverns so that we have a chance to get things straight. And you have powerful light mages that can stop the undead. Both of you need each other. Do you really believe that opposites exist to fight one another? Or do they exist to complement and complete one another?"
