Cult of the Dragon
The Cult of the Dragon worships all of dragonkind feeling that they alone are worthy of worship, having not used mortals like the Ancients and gods. However since Dragons actually care very little for mortals worshiping them is rather obtuse and not really useful to them.
Only the Elder Wyrms encourage worship, but this cult does not provide them with any power as the worship is vague and nonspecific. Their plots tend to revolve around purging the influence of both the Ancients and the Gods. This is the only reason the worshipers of the Elder Wyrms work with these madmen.
