As we all know we are getting this warframe after Lavos, a ghost warframe is something I`m looking forward to.
A ghost and a wraith are pretty much the same thing, to me their`s not really any difference. (correct me if I’m wrong)
Ghost – An apparition of a dead person which is believed to appear or become manifest to the living, typically as a nebulous image.
Wraith – A ghost or ghostlike image of someone, especially one seen shortly before or after their death.
