A wraith
Wraiths are spirit-beings, similar to ghosts, banshees and shades in that they are the spectral remains of a once-living person. Unlike banshees, who appear to be formed only from the souls of undead women, wraiths can be of either gender. They also appear to be of either elven or human origin most of the time. Some trolls in Zul'Gurub and the Sunken Temple manifest as wraiths before they die. Wraiths appear as partially see-through shapes with a roughly humanoid shape, although notably missing legs, and chains binding them to this life.
Wraiths retain their individuality and intelligence. These creatures are self-motivated and cunning and have all the memories of their past lives before undeath. Those memories no longer move the wraith nor provide any sense of morality other than a strict adherence to the wraith's own code of honor and law. Wraiths are lawful creatures, willing to make deals and hold to them. They respect the same tendency in both living and unliving creatures and will respond to honorable opponents with honorable actions. It is not unusual for a wraith to accept a creature's surrender; however, those surrenders will always be unconditional. Further, those foolish enough to surrender to a wraith are simply placing themselves into a position where they will almost certainly be turned into wraiths themselves. Wraiths fight well in units under the command of a necromancer, but if not so commanded, they prefer to fight alone. They are intelligent and cunning and will use the extent of their abilities to capture and destroy their opponents. In some cases, they will keep extraordinary enemies alive, preferring to turn them into wights and spread the plague to other "capable" individuals.Template:Cite
They are typically either bluish or purple, and turn into a little ball when destroyed.
