The Adventurer's Guide to Obsidian Bay
Our group maintains several Yahoo! Group Yahoo Groups which were historically used for in- and out-of-game conversations. That role has been taken over by the new message boards, but we retain the Yahoo Groups for file sharing and other tasks. Because of the private nature of the conversations, these boards are only open to campaign members -- if you are a new campaign member, please choose the "join" option when you reach the message board. The moderater for your campaign (usually the DM) will then approve you.
The primary Yahoo Group for our gaming group.
A campaign based in Delaware started by one of our guys who moved down that way. They occasionally adventure in their own splinter version of Obsidian Bay.
A group exclusively for campaign members from either group who are members of the Obsidian Tower.
