Cool!
It definitely has an excellent feel to it, very mythic in feel, if you know what I mean, without being derivative.
Which nations are you planning for the Shepherds, and which human nation is for the Baphomet?
Edit: I'd vote for developing the myth as far as you'd like to. IMO, the more backstory the better, and it is also interesting just for its own sake. I'd also prefer things be preset. It makes more sense that way and lets it be tied more into your vision of the mythos.
