Greyhawk Grognard has finished off his long running Greyhawk's World series, finishing the column that Gygax started so long ago in Dragon Magazine, that updates various regions of the Flanaess. This newest download details Events on the Periphery of the Flanaess like Blackmoor, Lordship of the Isles and the Olman Isles. I love "the Periphery" as a name for these scattered locations. Be sure to get Joe Bloch's latest article, it will definitely spice up your Greyhawk campaign. I know the added news dealing with the south seas lands will help in my own Saltmarsh-Sea Princes campaign.
Over at Tribality, Greyhawk superfan Blake Ryan has a couple new articles in his ongoing column on Greyhawk cities. This time he presents Greyhawk Cities-Yecha home of the roving Tiger Nomads. Pay particular attention to the "wedding quests." I love this idea. Also check out Greyhawk Cities-Sefmur as Mr. Ryan gives the Baklunish West some more love. Looking for a raid quest? There might be a certain witch-queen lurking here to give one.
This last one is from ENWorld. It's not Greyhawk per se, but it's a great article on the development of Deities & Demigods by the author of the AD&D book himself, James Ward. I highly recommend this read to all especially my old school friends. James Ward was instrumental in Greyhawk's early development as well so it's nice to know his thought process and how he and Gygax interacted. Enjoy!
