Author's Note: RUSALKA
According to Slavic folklore,a Rusalka is a water spirit or water nymph. they are the souls of young women or girls who died a violent or unnatural death. if a girl was murdered in or close to a lake, she would become a Rusalka and inhabit that lake. Rusalkas appear as beautiful women who try to lure men into the water, where they will drown them. With their shrill laughter they are capable of killing humans. A Rusalka's fate can be undone by avenging her death. Whenever people would bathe in the lake they would put fern in their hair so that the rusalka would not drown them.
