I’m looking at running the Myth-Speaker AP for Pathfinder Remastered, and I bought all 3 parts of the Adventure Path on Demiplane. I’m grateful for the Centaur and Minotaur Ancestries, but I’d like to manually add a Faun/Satyr Ancestry (I found one in a 3rd party book, Graungr’s Guide to Golarion - Ancestries of Iblydos), but I can’t see a way to do that. Is it possible to add a homebrew Ancestry?
