-shrug- I would, but I don't know enough about it to give the mythology justice. And, we do need some original ideas, not just a patchwork of myths from around the world...
:P Those are still a secret, though.
EDIT: As for Pony Europe, I also had some thoughts on that (it being an archipelago of sorts about half-way between the Elkwood and Equestria), and we may go there, but I don't have any story planned so far for it...
While I'm talking about story, once it actually starts again (ugh), don't be afraid to have your characters make plot-changing decisions! I have a general idea of what I'd like the NPCs to do, of course, but you're all free to trailblaze however you wish! Thought you'd like to know.
