In both Scottish and Irish mythology the Fachen, also spelled Fachan or Fachin, is a somewhat bird like creature with an appearance so frightening that it reportedly induced heart attacks in anyone who saw it.
Descriptions of the beast tend to vary and include such physical features as a single eye, a rooster like crest, a mane of black feathers tufted at the top and a very wide mouth.
The Fachen also was reported to have a single foot and in some cases is said to have only half a body.
One of the strangest physical features of the Fachen was its mangled, arm like appendage which is said to have jutted out of its torso. It was said that with this strong, singular, mangled arm, the Fachen could destroy an entire orchard with a chain in one night.
