From the back cover:
Faerie Skies is an alternate setting for Golden Sky Stories that moves the action to a small town in the English countryside, where there are fairies about. It introduces six types of fae: brownies, elves, gnomes, nymphs, pixies and pucas. You’ll also find some new characters for your stories, people with connections to the fae, animals of Britain, creatures of Faerie, and the Old Gods. To round out the book, there is the town of Westwick, some story seeds, and some suggestions for using other kinds of Golden Sky Stories characters in your Faerie Skies stories.
In order to play you will need the Golden Sky Stories rulebook, and the usual things it calls for (a few friends, pencils and paper, and some tokens to represent Dreams).
