Greetings everyone,
I'm the moderator of a Yahoo group dedicated to creating a richly detailed original campaign setting designed for d20 OGL (Open Gaming License) games. Basically, it's a brainstorming forum where a bunch of like-minded individuals get together and share ideas. Everything else you need to know is available on our site, which can be found at:
http://games.groups.yahoo.com/group/realmsofdarkfantasy/
As we intend to create our own original cosmology and pantheons of deities, I thought that there might be some experts on these forums who would be interested in brainstorming with us. That said, you don't have to be a Planescape expert or experienced DM to get involved - anyone who is creative and interested in creating an original setting is welcome to join.
A basic summary of our setting's historical timeline and a glossary of terms can be found in the 'Files' section of our site, and offers an introduction to those unfamiliar with the setting.
Thanks for your time - hope to see you on the forums.
