A fabled being is a mythical creature that appears in folklore and legends. The three most common fabled beings are gnomes, mermaids, and ogres. Gnomes are small, mischievous creatures that live underground and are known for their wisdom. Mermaids are half-human, half-fish creatures that live in the sea and are often associated with beauty and mystery. Ogres are large, brutish creatures that are often portrayed as villains in stories.
