How about this? they have two tiny vestigial legs on either side of their genitals that are only used during mating.
Sorry Elmo, I'm a biologist.
Oh, well that explains it.Wrong, dragonborn where created by 2 true dragons polymorphing into humans and getting it on. The female then stays in humanoid form until giving birth. These 1st generation born are actually half dragons and when they lay eggs, that's how you get dborn.
Hard to say for sure. But if they're like my players, it probably has something to do with dual-wielding halberds, or shields, or both.
Were the cultists upset by their new appearance and abilities or did they accept it as a close second to what they wanted?My dragonborn origin myth is a lot simpler. In my campaign, the first dragonborn were created when a large group of Tiamat's cultists tried to steal her magic and transform themselves into dragons, and she cursed them for their insolence.
