Litch
The lich is, perhaps, the single most powerful form of undead known to exist. They seek to further their own power at all costs and have little or no interest in the affairs of the living, except where those affairs interfere with their own.
A lich greatly resembles a wight or mummy, being gaunt and skeletal in form. The creature's eye sockets are black and empty save for the fierce pinpoints of light which serve the lich as eyes. The lich can see with normal vision in even the darkest of environments but is unaffected by even the brightest light. An aura of cold and darkness radiates from the lich which makes it an ominous and fearsome sight. They were originally wizards of at least 200yrs old.
Liches are often (75%) garbed in the rich clothes of nobility. If not so attired, the lich will be found in the robes of its former profession. In either case, the clothes will be tattered and rotting with a 25% chance of being magical in some way.
Habitat/Society: Liches are usually solitary creatures. They have cast aside their places as living beings by choice and now want as little to do with the world of men as possible. From time to time, however, a lich's interest in the world at large may be reawakened by some great event of personal importance.
A lich will make its home in some ominous fortified area, often a strong keep or vast subterranean crypt.
When a lich does decide to become involved with the world beyond its lair, its keen intelligence makes it a dangerous adversary. In some cases, a lich will depend on its magical powers to accomplish its goals. If this is not sufficient, however, the lich is quite capable of animating a force of undead troops to act on its behalf. If such is the case, the lich's endless patience and cunning more than make up for the inherent disadvantages of the lesser forms of undead which it commands.
Although the lich has no interest in good or evil as we understand it, the creature will do whatever it must to further its own causes. Since it feels that the living are of little importance, the lich is often viewed as evil by those who encounter it. In rare cases, liches of a most unusual nature can be found which are of any alignment.
The lich can exist for centuries without change. Its will drives it onward to master new magics and harness mystical powers not available to it in its previous life. So obsessed does the monster become with its quest for power that it often forgets its former existence utterly. Few liches call themselves by their old names when the years have drained the last vestiges of their humanity from them. Instead, they often adopt pseudonyms like "the Black Hand" or "the Forgotten King." Learning the true name of a lich is rumored to confer power over the creature. A lich is able to employ spells just as it did in life. It still requires the use of its spell books, magical components, and similar objects. It is important to note that most, if not all, liches have had a great deal of time in which to research and create new magical spells and objects. Thus, adventurers should be prepared to face magic the likes of which they have never seen before when stalking a lich. In addition, liches are able to use any magical objects which they might possess just as if they were still alive.
Defeating a lich in combat is difficult indeed, but managing to actually destroy the creature is harder still. In all cases, a lich will protect itself from annihilation with the creation of a phylactery in which it stores its life force. This is similar to a magic jar spell. In order to ensure the final destruction of a lich, its body must be wholly annihilated and its phylactery must be sought out and destroyed in some manner. Since the lich will always take great care to see to it that its phylactery is well hidden and protected this can be an undertaking fully as daunting as the defeat of the lich in its physical form.
