IIRC, no they won't, as it is crunch-light, and fluff-heavy.
So do yourself a favor : you can enjoy it safely.
Thanks. I'll pick it up.
With regard to what liitle crunch that does exist in the main Pathfinder Chronicles setting book, has anyone looked yet at whether any of that crunch is at oldds with the final copy of the Pathfinder Rules? In particular, I'm thinking of the class customization options that appears within the section that discusses the role of the various classes in Golarion. Do those little optional tweaks continue to mesh well with the final PFRPG rules?
