Oh and just in case anyone wondered…

Rusalka are from Slavic mythology, they live in lakes and rivers and are thought to be the souls of people who die violently and before their time, such as young women who commit suicide because they have been jilted by their lovers, or unmarried women who are pregnant out of wedlock, or the female spirits of the unclean dead; this includes suicides, unbaptised babies, and those who die without last rites (wikipedia -http://en.wikipedia.org/wiki/Rusalka)
