A few people have been working on creating a "World of Greyhawk Setting" data file for Pathfinder. It's an ongoing work and I'm doing most of the data entry/coding, drawing on 2nd Edition and 3rd/3.5 sources.

The file so far contains:
114 WoG Deities (7 Baklunish, 10 Flan, 21 Oeridian, 0 Olman, 18 Suloise, 17 General, 8 Dwarven, 11 Elven, 6 Gnomish, 6 Halfling, 6 Humanoid, 5 Orcish)
27 Greyhawk languages
24 Cleric Domains (from 3.5, to support the Deities)
Spells: multiple spells from 3.5 to support the Domains, 11 spells from 'Iuz the Evil'
Player Races: High Elf, Gray Elf, Wood Elf, 6 Human Ethnicities (Baklunish, Flan, Oeridian, Olman, Rhennee, Suloise)
NPC/Monster Races: Valley Elf, Wild Elf, Aspis (cow, drone, larva), Beastman, Booka, Camprat, Crystalmist, Dire Raven, Giant Raven, Horgar, Hook Horror, Ingundi, Mist Wolf, Needleman, Norker, Slow Shadow (2 versions), Son of Kyuss, Soul beckoner, Swordwraith (templete), Tyrg, Vampire Cactus, Vampiric Mist, Xvart.
Planned additions:
Prestige Classes, and more monsters. Also considering 'Greyhawk Regional Feats'.
The file size is too large to post to the forum (1MB), but I'm happy to email a copy to anyone who wants it. It's also available on our "Greyhawk in HeroLab" Facebook page. I'm looking to add it to the Community Files in the near future.
