I personally have worked with the fae in the past with a friend to help banish them from him home he made the mistake of messing around with them. They came at his call. Shortly after their arrival, my friends car broke down that was only 2 years old and very well maintained, as well as toaster coffee maker, dishwasher, stove, and washing machine, dryer kept working for some reason, as well as the wiring of his home that was less than 10 years old wigged out. Only after the banishing ritual did things calm down and things stopped breaking, but his little misadventure with the Fae cost him nearly $34,000.
The ones my friend worked with where elves but not all farries are like tinkerbell ether. Please just be careful with this because it can be dangerous.
In as much as I hate using wiki for another story about them I have heard this posted elsewhere and know their is some validity to it.
