I've updated my Barbaric Frontier Appendix N.
Some of them new to me some of them simply forgotten. The most influential on my creation currently is Weird New World By James Edward Raggi IV, his icy sandbox moved my campaign light years in terms of world building process. Reading through it, every paragraph sparks great ideas in my mind. I'm especially enamoured with the Living Aurora thing, I will certainly include such a thing in my game, ofc with few additions.
