So, here's the deal .. In my adventure that I'm getting ready to start, I'm wanting to have an evil god who descends to Earth and takes human shape as an amusing fat man. This leaves me with a conundrum ... How could I go about this? I want him to interact with the characters and then turn on them eventually, revealing himself and such, so I want him to be able to change form. My local hobby shop guy recommended checking out the Deities & Demigods book because it lists avatars in it, but, lo and behold, that's the only book I don't own.
So, any info?
