Fachin
In short
A fachan is a mythical monster from Scottish folklore described as having only one eye, one hand, and one leg.
In plain words
It is a strange creature that looks like half of a person. Instead of two arms and two legs, it has just one of each located in the centre of its body.
A simple example
Imagine a giant with a single eye in the middle of its face and a single tuft of hair on its head that is impossible to bend.
Why it matters
It shows how different cultures share similar monster stories. Some believe the fachan was influenced by similar creatures from Arabic traditions.
Easy to mix up
Do not confuse it with a Cyclops, which has one eye but a normal human body shape.
