Rusalki are mythical water spirits from Slavic folklore, often depicted as beautiful young women with long hair. They are typically associated with rivers, lakes, and other bodies of water. In many tales, rusalki are believed to be the souls of young women who died tragically, particularly by drowning. These spirits are known for their enchanting songs and playful nature, but they can also be dangerous. Legends suggest that rusalki may lure men into the water, leading to their demise. They are often portrayed as both benevolent and malevolent, reflecting the duality of nature in Slavic mythology.
