Necromancers:

[Chronos]

A Necromancer is an evil wizard who practices in the necromancy. Necromancy is the power over the world of the dead. Their powers enable them to raise corpses from the ground to create armies of Skeletons and Zombies. Necromancers steal the life-force from other living creatures to extent there own and to increase there strength and toughness. Often necromancers are from human stock but this does not rule out other races from practicing necromancy. Sometimes this power is also known as voodoo.
