I love the fey for many reasons, but I think the biggest reason is their amorality. When fey come into a story you never really know what’s going to happen other than the current state of affairs won’t stay the same for long. They tend to be very selfish creatures, but it's always fun to see them change and watch them put a human's needs in front of their own. I also enjoy the fact that there's such variety in fey stories. There's everything from the traditional to the modern and they all seem to hold to that amorality but they all have their own take on what it means to be fey.
Favorite fey creature in fiction:
Puck (Yes, Robin Goodfellow, he's been in everything from Shakespeare to Julie Kagawa's Iron Fey series.)
Favorite fey creature in pop culture:
Tinkerbell - yes, she's technically a pixie, but still part of the larger fey world.
