Now, you know exactly what you want. You don't pretend to want to help people or save the world. Your want is pure and simple and clean. And that's why you are worth saving; that's why we are going to work so well together. Because you -- you just want to eat.
After possessing Dean, Michael from Apocalypse World sets about working out how to conquer this new world. Over the course of three weeks he gathers information, speaking to all manner of people around the world. Ultimately, he finds their needs and motives complex and messy.
Following an encounter with a vampire that leaves him admiring its "pure and clean" need to eat, Michael commences a project of enhancing monsters through a process that involves feeding them a concoction that includes some of his archangel grace and the blood of the monster test subjects. He starts his experiments with vampires and although many die during the experimentation phase, he eventually refines the process. He is able to enhance the abilities of monsters and also reduce their vulnerability to traditional forms of dispatch.
Starting with the werewolf pack leader Philippe, Michael approaches different monsters and offers them a deal -- in return for having their abilities upgraded, they are to kill as many hunters as possible.
Enhanced djinn can read people's mind just by touching them and find out what they fear most; they can then cause these to manifest, and control them to do the djnn's bidding. They can be killed by bashing their heads in and one implies that they are still vulnerable to a silver knife dipped in lamb's blood like normal djinn.
