Finfolk are a type of magical creature that live in the sea. They look like humans, but with special things that make them different - they have tails like fish instead of legs! They can swim really fast and stay underwater for a long time without needing to come up for air. They also have special powers, like being able to control the weather or create strong currents in the ocean. Some people believe that finfolk can lure sailors to their doom with their songs, but others think they are friendly and will help those who respect them. Although they might not be real, they make for fun stories and are a big part of ocean legends and folklore!
