Fairies - The Dark Side of the Story

Over the centuries, they've gone by a bunch of different names depending on where the stories are told to. In some stories, fairies were said to be tall and beautiful, though others described them as bent and gruesome. While their motivation is never crystal clear in the tales about them, it's easy to walk away from those stories with an impression of creatures entirely absent of morality. If i can put them into the language of dungeons and dragons, fairies are chaotic but not malicious.
