According to the table of contents, the Gods section is 20 pages roughly, not including the section on religion in general, and in that section is a side bar on Mulhorandi Gods. Thier is also a side bar on Aasmir in the Tiefling Section, along with another side bar on Tiefling Variants.
I knew about that book (ibplan to buy it) but since it doesn't come out til next month, I wasn't sure which book he was referring to. I didn't know the Table of Contents was online for viewing.
