Let's start with the blog Greyhawk Musings and David Leonard as he continues to examine the collective cited sources of Greyhawk history. His latest installment continues the deeply rich background of the Great Kingdom from 300 CY through the Turmoil Between Crowns. This is the era of Zagig, Death Knights and a lot of political intrigue in the east. I've said before, my dream "period piece" of the Flanaess would be a sourcebook on 300-400 CY World of Greyhawk (the other being the Suel-Baklunish Wars). Check out this article HERE.
Next up is the tireless creativity of Joe Bloch over at Greyhawk Grognard. Joe and me have been on the same wavelength it seems, talking about the Pomarj on stream and writing pieces on warfare involving the Iron League. Where we differ is Joe is a fan of miniature gaming rules (he is exploring the Triumph! ruleset), whereas I tend to be lazy and use counter/card abstracts for my campaigns (Warmachine, Greyhawk Wars, Birthright). Joe is very adept at adapting Greyhawk armies to mass combat rules. Check out his article on the Army of Idee. He does his homework when crafting these armies, immersing them in the lore of Greyhawk. Joe is a true wargaming legacy of Gary Gygax.
current Greyhawk campaign and its planar-gate connections. Grodog, who I associate with old school Castle Greyhawk normally, gives a good run down and some graphics on what other worlds and planes he is tying together. It's all quite fascinating world building stuff. We all like to reach beyond the game-world we use. I know I used to do a lot of Planescape and Norse mythical adventures, but Greyhawk was always the core setting. I will be keeping an eye on his campaign moving forward.
Finally, Thomas Kelly over at Greyhawk Stories continues his epic tale of the Hateful Wars with Chapter Fourteen: A Voice in the Dark. If you think a mimic is in this part, you are only partially right. Follow Kristryd and company as the action gets very deadly in the dark tunnels beneath the Lortmil Mountains. Enjoy the latest chapter or if you are just now finding out about the Hateful Wars, go back and read from the beginning. Enjoy!
