The Fairies Are Afraid of Seven Things

The fairies are afraid of seven things. The best thing to have if you meet the fairies is a black handled knife, and they'll keep well away from you. If you haven't any of those six things, well, run, run. But there's no point in running from them if you think you're going to get away from them by running. They can't cross flowing water, those seven things. Something holy, something dirty, something red, the color of blood,. Iron or steel. Salt fire.
