Undead Necromancer

Undead.....

They are souls of the dead that have stayed in the Land of the Living through their resentment.....

One undead, a skeleton in fact managed to evolve to a Lich....

This doesn\'t usually happen since skeletons would be killed by the hordes of zombies who are physically surperior to them.....

But when a skeleton does evolve it can have catastrophic changes to the world.....
