Fiura is a mythological creature or a legend in the region of Galicia, which is a place in the northwest corner of Spain. People believe that the Fiura is a woman who has a very scary face, with big eyes and a big mouth that has lots of teeth. She is also believed to have long hair, and her body is covered in fur. She is said to be very fast and sneaky, and she loves to play tricks on people who are in the forests, mountains, or near the rivers.
The Fiura is not always visible to people, and some people think she is a spirit or a ghost. She is said to be helpful to some people, but also harmful to others. People believe that if you see the Fiura, you are supposed to try to run away or hide from her, because she might harm you or play a trick on you.
