Hey Ron. I am one of the DMs for the Living Guild Campaign. We run stories that are loosely tied together with a ton of players and several DMs. We have a Darksun plotline if that would help your Darksun fix and a lot of other ones as well (Some in the realms, some in Eberron, some in completely new and interesting dimensions). If you are interested toss me a PM and I'll get you whatever other information you need.
