So I just picked up Ghost of Saltmarsh and I have only read the first chapter but have scanned it over many times. I'm really enjoying the write up on Saltmarsh. I've always played and ran games in FR and have setting material for that setting (old grey box). My question is, what is a good start for Greyhawk material. I wish to learn more about the setting. I DM 5e but if I'm not mistaken this setting never really got an update through the editions did it? Any suggestions would be much appreciated!
