Lich

Liches are undead beings that formerly were once beings (or any creatures that are capable of intelligence and speech) that used the Dark Art of necromancy to give themselves a false sense of immortality. They do this via an ancient ritual that rips the soul from the body and binds it in an object known as a phylactery. This object can take the form of any kind of object, usually the former being's most prized possession.

Appearance
Liches tend to look normal to their race until they perform the ritual, then pretty much all of their normalcy is stripped away until they look like an animated skeleton, wearing tattered clothes. Also, usually there will be glowing orbs of magic in place of their eyes.

Behavior
When one becomes a lich, one will find that one only has one thought in their mind; EVIL! They usually have their own personal goals, of which they will do whatever it takes to see those goals come to fruition, anywhere from gaining more power to seeking dominion over all.

Weaknesses

 * Phylactery: A lich's phylactery is not only their greatest strength, but also their greatest weakness. The object that becomes the phylactery holds the lich's own soul, and as such, if the phylactery, and therefore the soul, is destroyed, then the lich will be no more.
