So there is a song I remember from a while back that I remember liking, but I don't remember the lyrics clearly and forgot the name of the artist and name. I remember that the video had a forest. Two children were running into it, one boy one girl. Then there was a woman in a sort of winter dress who had snow following her and at a certain point the while forest was covered in snow. Then she begins to seemingly protect the children from an enemy as her dress is now made of fire! Any help?
