The Snow Maiden
The Snow Maiden, a freak season, is born when Old Man Winter (Ded Moroz) and Lady Spring have an affair. As a result, nature has been disrupted and the earth is covered in eternal frost. They name their bastard Snegurochka and raise her isolated from humanity out of shame. But, the more Snegurochka grows, the more she yearns to join human beings and feel love.

When she's finally old enough, Ded Moroz relents and releases his daughter into the world. But, upon falling in love for the first time, Snegurochka is overwhelmed with emotion, and her frosty body melts into nothingless like frost in the sun. Her sacrifice finally frees the world from eternal winter.

Modern Snow Maiden
Modern depictions of Snegurochka are popular in Russian Christmas celebrations, and she visits houses on new year's day (when Winter turns into Spring).

Most modern retellings cast her as Ded Moroz's granddaughter instead - while he occupies himself with helping the grownups, the younger Snegurochka's duty is to take care of the children.
