Perhaps instead I should plan one or more modules/adventures, each focused around a specific 9 and 30 Kingdoms-related concept, plus additional material related to that concept. For example:
- A goblin dungeon built around my idea of insane, semi-intelligent goblins instead of a " savage humanoid race with a legitimate, if primitive, culture", with a section on the goblin backstory from the 9 and 30 Kingdoms, which can be adopted by others as the backstory for all goblins in their campaign or just one small tribe.
- An adventure to find/loot one of the lost elven homelands destroyed by the worms, again with the material on elves and other backstory that can be adopted for your entire world or just for that adventure area.
- An adventure that features both neutral and chaotic orcs and chaos druids, plus backstory for the cult of Red Orc.
It's very tempting, but I have no idea how interested people are in really divergent interpretations of the traditional races.
