Rusalka

'I come from dying. When girls or women die due to an unnatural cause, or they've lived a very bad life, they turn into spirits that cannot find their rest in the other world. So we are bound between the world of the real people and the world of the dead people. '
          Violetta Korbina, playing a rusalka river spirit at Kupala in Brighton.

Rusalkas dwell in the rivers; the forests are haunted by mavkas.
