@MNblockhead this is your chance: convince me not to downvote St. Cuthbert. I don't have a lot of skin in this battle (I just don't like his name), but you seem to care. So why do you care. I will give you until noon EST to prevent my downvote - go!
The really weird partis comparing Greyhawk "St. Cuthbert" to the actual Anglo-Saxon Monk of that name...St. Cuthbert is one of the two oldest gods in D&D history, created alongside Pholtus by Gary Gygax in 1972.
I love the paradox of the name. A god who is a saint. I like the crossover with the real world (mace in a London museum, plus the obvious inspiration from a real-world figure). I dig the sincerity and out-of-place normality of St. Cuthbert. I liked that he never really crossed over into other D&D pantheons. He's a quintessential, syncretic, somewhat incongruent, Gygaxian creation from the early days of the game and triggers warm nostalgic feelings in this old, common-yokel grognard.
