The Gwyllion is a mythological creature from Wales. Even though these elfish creatures are mostly harmless you should always invite them into your house and treat them well, because if you don't, it may result in destruction. The female faerie is very hideous and its only job is to cause travelers to become lost. Many times they just bother you or possibly frighten you by sitting on either side of a mountain path and following the traveler with their eyes. These ladies usually like on mountain trails, but if the weather becomes bad they resort to going to the valley. If you do happen to be threatened by a Gwyllion just take out a knife and point it directly at her. It is strongly recommend to have a knife handy if one plans on hiking in the night time, for this is there prime time for terror. Just beware next time you plan on going on any trails.
