A Fifth of Greyhawk: Introducing 5E Players to Oerth. Be sure to also check out Part 2 of this series. For those who don't remember, Mr. Roy did an excellent article on Greyhawk for Dragon+ back in February. A lot of what our community is invested in lately is outreach and education of new players getting into the World of Greyhawk. John is certainly a good new high profile voice and I'm glad to have him involved.
Read his articles and get in on the discussion. Enjoy!
