There are a few (general) questions that you may want to answer before goign full-tilt with the process, as well, so you can establish a baseline of How Things Work in this new setting:
- The power of the Divine: Is there one monolithic pantheon of deities that preside over everything, or are there multiple pantheons based on race/region/etc.? If it's the latter, how do they interact?
- Arcane matters: How is Arcane magic viewed? Is it accepted? Embraced? Rejected? Persecuted? Rinse & repeat this idea for other non-mundane methods of power (primal, psionic, technology, etc.).
- What's the Story?: What's the big things you want to have/achieve in the setting? Is it a grim, dark world dragging itself from the brink of oblivion? Is the world entering a Renaissance of sorts, achieving new heights of invention & knowledge? etc.
- The Good, the Bad, and the Ugly: Who're the good guys? Bad guys? Not-so-nice guys? Why are they that way? Is there a hard & fast clear-cut definition of good & evil, or does it all depend on a certain point of view?
