And, after repeated scouring of histories and what little we really have, there is more to suggest that it is impossible to untaint something that is not immortal (IE Fae, Angel, Demon) than possible. Isune had mentioned in a few threads of doing an RP between a couple celestians and a captured Mag in an attempt to remove the Taint without killing the subject.

I stand by my Soulless/Weave analogy.
