The Magical World of the Fae Event - Welcome!

For November and December, we will be exploring the Magical World of the Fae. With new interviews, excerpts and more, we will have new posts every Monday. 
The Fae range from fairies, to sprites, to brownies and elves. There is so much variety and so many creatures to write about. 
Here in Ireland, we have many legends about fairies. Banshees are the most famous - a wailing woman who predicts the death of certain people by wailing at night. She is definitely one type of Fae you don't want to meet.
Changelings are another type of Fae where a human baby is swapped for a Fae child. This was often used to explain disabilities a child may have had back then. 
The Fae are complicated and while a lot of them are not strictly bad, they are mostly seen as tricksters. They may help humans from time to time, but they always have a price. 
What are your favorite types of Fae?
