I'm copying in a Q and A from the proposal. Feel free to disagree and post new answers.
For instance, the Commonwealth Saga has a lot of details about the worlds in it, especially in the two novels set earlier in the timeline. Would questions relating to how certain effects might be explained or questions about how you might reproduce the Silfen world that Ozzie visits?
I can see people being inspired by worlds like that and wanting to understand them, either for the purposes of running games in them, or adapting them for their own stories.
