So, I have to mention Fayon first. He's been the chief god of all of my homebrews, so has a lot of lore built up around him. His portfolio is justice, wise rulership, and barbers. As I mentioned the other day, he was a character of mine from the 80s who eventually, through the dynast path, became an immortal. There's a bit of backstory that I'm not going to reveal so I don't spoil my players, but there's one thing you might be wondering. Why barbers? Well, I've always liked the idea of having gods wandering around the setting, like Fizban, but never really liked the character. I played around with a few ideas, but I think I've stuck with the idea that he likes taking the form of a traveling barber. So there you have it.
I'd be remiss, though, if I didn't mention my favorite canonical deity, St. Cuthbert. When I first heard of him, I thought it was a fantastic idea. An old school Catholic guy wandering around Greyhawk? Sign me up! Plus, the idea of a god carrying around a cudgel is just great. As far as it has affected my campaign, it got me around a limitation on the number of deities. For a while, I've had a pretty hard cap of nine major deities. It's a good number to have -- enough for some diversity, but not so many you couldn't keep track of them. But then one of my players wanted to play an assassin, and I decided that the church should have an order of assassins. But it didn't fit the portfolio of any of the existing gods, so what to do? Well, that's how Saint Carino was born, the first known saint of Arden Est.
