I'll just say that I have a few regrets that I didn't put in some more interesting options in the Gyre, or, like, scattered special hard-to-find bonus planar icons around the adventure path. I'd certainly do that if this ever got made into a video game.
There aren't enough good options in the Gyre, and plenty of obvious "no" options. And I think Mavisha works better as a space and water plane (since islands are far apart) than time and water. There weren't enough good time options.
