While searching for material on Fey races, I found a WordPress site that already has some good ones. Here is his link: https://newpathfinderraces.wordpress.com/2014/11/30/brownie/. So far he has brownie, pixie, grig, treant, korred, nymph and satyr. He also has some other races: gargoyle, grindylow, boggard, derro, evolved gorilla, ghoul, lamia, lizardfolk, soulbound doll and terrapin. I like his advanced race builds.
