The magic of the dead, Necromancy deals not with the spirits of the dead, but rather with the necrotic energy that is found in the realms of the dead, and the uses of that energy in the mortal plain. Necromancers animate dead bodies, but can also animate objects, and even the air. They also fuse necrotic energy to their own bodies, or their instruments of the art, to strengthen them. It is a powerful tradition, but rarely practiced, since it is outlawed in some places, and very unpopular or even persecuted in others. Due to these reasons, it is difficult to find a source that would teach you Necromancy, while it is impossible to study it on your own.
