Kikimora — Russian fairy tale character

Kikimora is an evil spirit, and she appears in two forms, depending on who she marries. There’s the Bog Hag, who is married to a hobgoblin, and the House Hag, who is the wife of Domovoi (a house spirit in Slavic folklore). The Bog Hag appears in fairy tales as an ugly old woman clad in seaweed. Her jobs are to frighten those who wander through the marshes, lure travelers into quicksand and steal small children.
The House Hag is quite different – she lives quietly in her house and rarely shows herself to people. Legend says that hags are most often the souls of people who have drowned, or of children who died before they were baptized. The most well-known tale of the hag is “Kikimora,” by Alexei Tolstoy.
