BV210: I've got some leads to get my hands on this issue (gotta love ebay) - the circus is on the cover! I hadn't given much thought to a rival circus mostly because the circus itself is an anomaly in its part of the world. BUT... if the PCs can convince the Ringmaster or enough other folks to take thier act into human lands... there would definately be other circuses.
In other news, still working on the Ringmaster. I think I've settled on a Monk who left his Order to chase prophecies. Still haven't decided if he's a good or black hearted sort.
I'm working out the details of the Order, who they are, what they do and all that good stuff.
Again, thanks for all the ideas. Feedback is appreciated.
