Elmo and Meleny both are Old Faith in protos already. Meleny has a wisdom of 17 and Elmo 16. Both would be decent clerics with sun domain and greater turning.
Right, but that doesn't help player character Druids who maybe ought to be old faith. I guess Beory is an obscure religion limited to Homlett and not nearly ubiquitous like the other religions seem to be?
Druids were a particular type of sage / holy man. They wouldn't have been of any one particular religion. They are supposed to be manipulating natural forces rather than any particular personality.
Reading through my Greyhawk compedium and the Manual of the Planes books, it seems that all druids in Greyhawk worship Beory. But, in the TOEE system, the choosing of a god is only for characters who may become clerics. Druids could multi-class to cleric, but must choose another god so they can receive spells and choose domains. From the Manual of the Planes, it seems that Ehlonna and Obai-had have an unfriendly rivalry. Ehlonna lives on the Neutral-Neutral Good plane and believes in the goodness of nature, and lives in a grove protected by centaurs and unicorns. While she has many druid followers, she is really the dominate god of good rangers. Obai lives in the true neutral plane and believes in survival of the fittest, the true animal nature god. Each god's cleric followers may have some 'disagreement" with each other.
A fighter (Elmo) can worship Beory, too. But he doesn't have to. You don't have to choose a deity to be a druid. But you CAN worship a deity if you ARE a druid (or a Bard, or a Wizard,...).
Except Elmo isn't level1 so he doesn't become a very useful cleric, and sacrifices fighting skills. Less relevant since the lv20 cap though. Still, Meleny is more perky, and is level1. Also a follower of the old nature god.
One thing that I do miss is 'godless' clerics. In D&D 3.X, clerics could choose two domains and not chose a given god. That way they could dedicate themselves to the domains as 'metaphysical concepts' as it were... Here from the SRD: So if you wanted to have the war and sun domains, good. On the downside, you'd lack a proper 'organized religion' and might not have preferred weapons, end such other characteristics attached to deities...
