Inferius

An Inferius (plural: Inferi) is a corpse controlled through a Dark wizard's spells . An Inferius is not alive, but rather just a dead body that has been bewitched into acting like a puppet for the witch or wizard. Unlike ghosts, it is apparent that Inferi cannot think for themselves. They are created to perform a specific duty assigned by the Dark wizard who commands them, remain idle until their task can be performed. This task is then thoughtlessly carried out, whether or not it will produce any result. Inferi are difficult to harm by magic; however, they can be repelled by fire or any other forms of heat or light, When defeated, they return to their idle state.

There are two main differences between ghosts and Inferi. The first is the aforementioned fact that ghosts have an active consciousness. The second, is that ghosts are transparent and retain their sense of being. Therefore, ghosts and Inferi are opposites: one has sentience but no body; the other a body but no sentience.
