My plot point on necromancers, and why they are hunted.

[I]-The world was almost taken over by a necromancer once before. A powerful mage by the name of Osvin who lead an army of corpses overseen by thirteen dread generals, or death knights as they would come to be known. Beings who fed off of sorrow and grief, each being emotionally broken in their own ways to create their own loops, but unlike the main character here were completely subservient to Osvin's will. He was eventually defeated, however, though it took the combined efforts of the entire world to accomplish. This near loss on the part of humanity is the main reason why necromancers are as feared and hunted as they are.[/I]
