Fairies come in all sorts of guises some look like Goblins, a typical fairy is a tiny human like creature that is 12 inches high, and has delicate wings on its back. These creatures tend to be friendly with humans but humans rarely ever see them. Fairies tend to have specific purposes like the tooth fairy that goes round collecting teeth that are placed under pillows and swaps them for some money. Sometimes fairies are guides to lost people.
