A selkie is a mythical creature from Scottish and Irish folklore, often depicted as a seal that can shed its skin to become human. These beings are said to inhabit the waters of the North Atlantic and are known for their beauty and enchanting songs. Selkies are often associated with themes of love and loss, as they can choose to live among humans or return to the sea. In many tales, a selkie's skin is a crucial element; if a human finds and hides it, the selkie may be forced to stay on land and form a bond with them. However, if the selkie retrieves its skin, it can return to the ocean, highlighting the tension between freedom and attachment in these stories.
