* 2 kinds of undead, the soulless and the ones with a soul.
* Soulless obey the commands of its creator without question and will carry out its final command even it its creator dies. Ex Zombies.
* The ones with a soul still have their intelligence. They still have their own free will.
* Some of the undead that still have their soul are trapped within a body. They do however have the problem of the fact that their bodies are dead, which means that they do not heal. If they don’t do anything to prevent it, they will end up with bodies that are so destroyed that they can do anything. Ex Vampires
* There are also undead that are nothing but souls such as spirits. This type of undead are very dangerous as they can possess people as well as inanimate objects. They are very difficult to kill as while in the natural form, they are unscaved by physical force. At that point you need magic to deal with them. However, if you kill a person possessed by one, you will also kill the spirit.
