Undead

Being 'Undead' on Elion is an affliction that manifests through a disease or magical power normally.

For sentients, there are very specific types of Undead: There are also Wights, which is the general term for undead that are non-humanoid, so undead dragons, undead dogs, etc..
 * The general undead are mindless beings that seek certain objectives. These are generally ghosts, zombies, and skeletons.
 * Revenant are beings that retain their minds, and are generally liches, ghouls, some vampires, and phantoms.
 * Vevants are undead that have survived dying through sheer willpower, and are incredibly powerful dark beings. They are generally made through intense misery and pain that creates a strong desire for revenge. They normally leave people alone, excluding those they wish to destroy. To put into perspective the monumental amounts of willpower required to actually create a Vevant, you would need to find the happiest, most loving, caring person around and then slowly torture everything he cares about through permanent mutilation, leave the person and the things that person cared about to wallow in misery while constantly taunting and/or continually torturing them, and make their life a general living nightmare of their deepest agony. You now have a 1% chance of creating a Vevant.
