Fachan

Fachan are a frightening, malformed and extremely violent type of fairy, goblin or lesser demon from Scottish folklore and mythology - while all fairies were seen as capricious and dangerous beings in folklore the Fachan are particularly malignant and are said to absolutely loath all other life.

Thus Fachan are noticable by their lairs often being devoid of any and all life, the vicious creatures having murdered any non-Fachan in the nearby area - this includes animals and other fairies, if given the chance.

Lukily for humans Fachan are deformed and awkward beasts who have only one leg and arm by which to travel, they often carry large clubs or other weapons - a single cyclops-like eye glares out of a goblin-esque face and due to these strange features the monster can be dodged or outran, if victims are not quick or agile enough the Fachan will not hesitate to brutally beat them to death with their weapons, driven purely out of hatred of non-Fachan.
