Nargles

Nargles are fictional creatures from the Harry Potter universe, created by author J.K. Rowling. They are described as mischievous, invisible beings that are often associated with stealing or hiding things, especially around winter. While they are not real, they serve as a whimsical explanation for missing items or unexplained disruptions by characters like Luna Lovegood. In summary, Nargles are imaginary, playful entities that embody the mysterious or inexplicable happenings in the wizarding world.
