This is something that I've been using for other writing projects, which I'll also heavily use in tinkering with my game. It gives a great deal of information for free, but also has some resources for sale. Free resources include character, map, backstory, and language creation, a podcast, and online novels. It's Holly Lisle's website, she's the author of Talyn, among several (dozens i think...)other books. She's got tons of great advice.
