Yes, I like dragons but the Dragonborn always just kind of felt “meh” to me. Sort of dragons but not quite. And some overall feeling that they were just tacked on to D&D as a fanboy service. They just didn’t seem interesting. So instead of telling you what to do. I got some inspiration from Obscene Serpent Religion. Use it for a little inspiration to get those creative juices flowing or just roll and see what happens.
