And that is precisely why Nentir Vale and Exandria are superior settings to the FRSeriously, what setting needs that many deities?! It's like Discworld, with its Rat Death and God of Things Lost Down the Drain. Downvote the lot of 'em into oblivion, I say!

(I guess Theros and Eberron would also count as settings with fairly small lists of deities, too. They both have 15.)
