This is a news update for the Mutant Earthers. YE GODS! We're going to play on Friday? I've got some work to do.

Therefore, let it be known that the four classes of the Mutant Earth shall be, now and forever,
The Omnidisciplinary Scientist and
The Metafaceted Humanitist and
The Panarcane Reconditist and
The Multibelligerent Uberpugilist
