Rebirthed

The Rebirthed are a group of creatures that are formed when the corpses deceased beings are reanimated and rise again. They are mere husks of the people that they used to be. Their presences and identities through their hearts and souls having left their former bodies and moved on to the next world. (The primary difference between the Rebirthed and Nobodies being that Nobodies still contain the soul even if the heart is lost) Leaving only empty, mindless drones behind that are mutated by the process of reanimation and the loss of those important components. Their lack of hearts keeps them from feeling emotion, and their lack of souls keep them from having an independent will. And thus they can be controlled by any beings with strong negative feelings or darkness. Though their lives are restored, it is only temporary. Forcing them to have to drain the life force out of any living things they can find to keep themselves going. With the ability to store reserves of power within themselves. However, it is possible for their victims to end up turning into Rebirtheds as well, increasing their numbers.
