Wraith

Wraith is the term used to those who have been raised from the dead. This form, usually attained by the use of necromancy, gives a physical body to those resurrected as opposed to ghosts or spirits who maintain an ethereal form.  
Wraiths are bound to those who resurrect them. Should the one they are bound to die, the wraiths soul will be detached from the body and will once again depart.
Wraiths generally retain all their physical attributes from their living days. More so than just retaining, some of these attributes can be enhanced if the one summoning them is powerful enough.
