Has anyone linked The Twilight Tomb and Sons of Gruumsh? How did it go, and any advice on how to best link them together? Also, would these then link well with Cormyr, Shadowdale and Anauroch?? I'm planning on running these once I am done with the Undermountain adventure. I see they are set in relatively close but different areas.
I wouldn't have described them as relatively close.
I DMed Sons of Gruumsh and moved it to Semphar, and replaced the standard Orcs with Gray Orcs and jiggled other bits to fit the rest of my campaign arc. A DM must never be afraid to alter an adventure.
Upon further inspection I see that I could link Sons of Gruumsh with the many adventures in Mysteries of the Moonsea....which is perfect since the adventures in there are to be linked by the DM already. Good stuff.
