Rusalka's Conflict

Have you ever heard of a Rusalka? Well, a Rulsalka starts as a woman who has died a tragic death by a lake. They are given new life as a spirit to kill for the lake by way of murdering their victims. They are to be tied to this fate like a farmer to the land. She is trapped in an eternal blood lust locked by these waters. This however does not stop her from being kind, she may help water mans' crops in the spring, or meet them and fall into love. Who knows? Maybe she isn't as evil as she believes herself to be.
