Info
They were the originators of the concept of godhood. All tabletop gaming gods have them to thank. If it wasn't for them, they wouldn't exist. On the flipside, if it wasn't for them, the Ebon Dragon and the Chaos Gods, among other evil gods, wouldn't have existed either, so it's sort of a mixed bag.

The Random Number God comes to them sometimes for guidance.
