The Dragons came to Endunia through a portal in the sky long after mortals began traveling the world, but the Dragon gods had been known to them one way or another for ages. Before this time, the word Dragon in many languages was synonymous with Bahamut, and Dark Dragon with Tiamat. When the Dragons came to Endunia, worship of their gods spread amongst all the races, particularly Humans worshiping Bahamut. Good Dragonborn usually worship Bahamut amongst the pantheons of other species, while unscrupulous Dragonborn may serve Tiamat, like their ancestors before them.
