On RPOL.net I've just set up a new Birthright campaign. There is room for more players if anyone is interested. It uses the BRCS rules. Realms and Domains are available, and more will become available if there's interest. Currently open are Southern Coast and Eastern Reaches. Next to open will be Heartlands, then Western Coast, if necessary.
