Erik Mona very kindly doled out some data on Iomedae and Aroden in the General Pathfinder Forum. It's subject to change because some of this material is still being developed- but hey.. it was damn nice of him to do it.
I know a lot of people have speculated on Iomedae and Aroden in this Forum too.. So I wanted to throw up a link to help my fellow GMs.
