It was among the dervishes that the babas, scantily clad in animal pelts, with their shaven heads and fondness for loud music, were welcomed with the fewest reservations. (p. 23)Sounds like punks and metalheads (those who all liked speed and thrash metal, at least) back in the day.
Makes me think I need to create a dervish class for DCC. The baba class might follow, but I think that the Savage class I wrote for last year's Secret Santicore (Vol. 1, I think) would fit that particular bill. Heck, it might do the job for both of these, but I think the dervish would be a bit more like a specialized paladin/sage type.
