... there's about a half dozen alternate campaigns planned, actually. You can scrum through some of the various development ideas still lurking around
here, albeit somewhat unorganized. Though don't ask me where anything is in it, ha. Still, beyond the orcs, spiders, trolls, the tentacley dudes, naga, and I think one or two more have been mentioned at one point or another as possible campaigns to be explored after the base Maj'Eyal one is complete, assuming they're all still on the table.
Incidentally, the git's also a good thing to RSS if you want to see if any work's being done. Even when there's not a major update push, it's not uncommon for stuff to pop up on the git.
