I was looking through my new copy of Vornheim, and I became disappointed in the lack of a random cult* generator.** So here is one I just made up:
The [Table A] of the [Table B] [Table C] -- Worships a [Table D]

* Technically a cult is any religion that venerates one god above others, making 99% of clerics cultists; however, this definition is really terrible when applied to how the word cult is used by most people. For the purposes of these tables a cult is a religoin that does not actually worship a god of goddess but thinks it does. In some systems this definition would mean that the cult should not have clerics. That's perfectly fine, if not desirable. The upper echelons of the cult should be filled out with magic users or anti-clerics, whichever makes more since with your chosen system.
**Vornheim is otherwise an excellent product. Cults are just something I shove in everywhere.
