This is a group for the others: the wise old man with the life-changing advice, the mysterious woman who whisks the child of destiny away from danger, the elf who offers the one sword that can slay the evil. We aren't the heroes or the heroines ... we aren't even necessarily part of the team. Nevertheless, we are there, behind the scenes, making sure that everything ends happily ever after. Whether you work for fame, money, or the simple yet important goal of making the universe a better place, know that here, you are among friends.

Or, more directly, this is a group for writers and other creative-types whose work sometimes/occasionally/often focuses on the mysterious stranger archetype.
