I will be a player in a Radiant Citadel campaign. DM is planning to select and link several one shots and wants every PC to be from a different selected civilization. I can suggest a one shot, but I don't want to read them all, even just the gazetteers.

Could you let me know which cultures have some beings perfect to be a good paladin's god? I'd like my PC to be a paladin from one of the civilizations and I'd like to read only about that civilization before playing and learn about the rest as I play.

If there's any culture / religion / setting that would be fitting for an earth genasi oath of the ancients paladin specifically it would be perfect, but I'm flexible here.
