General rule of all fictions, unless you have a body there not dead BOCTAOE (But of Course There Are Obvious Exceptions, thank you Scott Adams)
General Rule of fictions where magic is prevalent, unless you have a body, have seen it COMPLETELY disintegrated, soul bound the being into some containment unit, and sent that containment unit through at least three different planes there not dead. Further this does not rule out undead.
Edit: *Reads NS news* and speaking of Undead...
