Devouring corpse

As demons pass through the Veil into Thedas, they seek out that which they desire the most: life. Being unable to distinguish between something which is still living and which no longer is, many demons will possess the bodies of the dead. Trapped within the lifeless corpse, the demon will be driven mad and will lash out at the truly living around it.

A Devouring Corpse is the name given to a dead body that has been possessed by a Hunger Demon. It possesses a ravenous appetite and will seek to feed on any living thing and will seek to feed on any living thing it finds, and many of these creatures have demonstrated the ability to drain the very life force from their opponents.
