Man, the pdf's look fantastic. Nice work. I really like some of the god names. I love your take on using 'real' gods in rpgs (I've totally agreed with that ever since the 3.0 FRCS used like the entire egyptian pantheon!).
I'm not that familiar with Grayhawk; did you create all those gods? I would have liked to read some details about cultural rules, rituals, taboos and roles.
