Necromancy
From DALpedia
Necromancy is the dark art of reviving the dead and turning them to zombies. This is sometimes considered a form of Black Magic as those who practice necromancy tend to fall to evil. With necromancy you could also create things out of the dead bodies such as strange combinations of dead body parts and bringing them to life. The biggest example of necromancy is Kronos. There was also a necromancer who was a helper of Mavas, named Degzgronzo.
