Man... we published that book like, what, 4 years ago? Sorry man, I just don't recall off the top of my head. When I get a chance I will grab a copy of the book and try to refresh my memory, but it might not be right away. Buy something we published in 2007 and you'll get a faster answer.
Any luck on this? I'll have you know I did recently purchase 7 DCC adventures from my FLGS(Revenge of the Rat King, Aerie of the Crow God, Mysteries of the Drow, Curse of the Emerald, Citadel of the Demon, The Slithering Overlord, and Secret of the Stonearm.) I just have a PC who was interested in the Arachials. (We have an evil campaign going.)
