And that's why you read the role-playing fluff

I don't think I shared this story: a while ago, my partner DMed a one-shot for some friends, and one of the players tried to talk a gold dragon out of attacking them by saying "I too am a worshiper of Tiamat, we should find a peaceful solution!"

This is basically the D&D equivalent of walking up to a Catholic nun and saying "I worship the devil too" except the nun can breathe fire.
