Rusalka (plural Rusalki) in Slavic mythology is ghost female mermaid that dwells at the bottom of river. Rusalki are spirits of young women who died violently before marriage and before their natural time was up.
Thus, they were cursed to live in a lake in the form of a mermaid. There they will sing sweet songs to entrap men into the water and drown them.
Rusalki have pale, almost translucent skin and no visible pupils, though depending on what versions of the myth you read, they sometimes have green fiery eyes. With green or golden hair, which is always wet, and some believe if her hair ever dries, she will die.
