While reading some of the archives of the Mimir.Net mailing list I encountered the "CMV Hypothesis". In short, it says:
Under the CMV hypothesis, Eladrin, Guardinals, Asuras, and Aasimar are all one race; Aasimon and Archons are not. [Galen, 1999 archive part 3]
After reading several posts about this hypothesis, I still can't figure out what 'CMV' is supposed to stand for. Web searching is confounded by a biology hypothesis of the same name.
So what does the "CMV" in "CMV hypothesis" stand for?
