Two questions: Is there a certain pantheon we are following for this roleplay regarding deities, or do we just sort of make our own?

And while we aren't using mechanics, is it possible to be one of the supplement classes/races?

As for supplement classes and races, which one(s) were you thinking of? While I intended for this to be based around the traditional (core) things, alternatives can be approved on a case by case basis.
