FOr me, that's the appeal of Greyhawk. That it really is such a blank canvas. If I wanted a library of lore and canon, I've got Forgotten Realms for that. Greyhawk just has so many "Here Be Dragyns" blank spaces.Heh, I set a campaign in Sunndi many years ago. I'd suggest looking for the content created for the Living Greyhawk campaign.
Yeah, that's pretty much low-hanging fruit. There's just so many places you could pop them because, like you said, Greyhawk is pretty open and empty—just waiting for an enterprising DM to fill in the blanks.
