On a sunny afternoon on a clear grassy hillside, a ring of mushrooms lures a child into its midst. On a starry, moonlight night, while walking through a forest, a weary traveler leaves the path when enticed by dancing, flickering lights. Maybe they sneak into a house and replace a newborn baby with a changeling. Maybe they come into the house, welcomed with bowls of milk and slices of thick bread, and repair broken things or do chores. Maybe they are good-natured but easily sidetracked; maybe they are bad-natured and only out to do harm. The stories of fairies are legion, but one thing is certain. They need a home. And all good homes have doors.
