Inside one of the rooms of Arendelle Castle one evening, young Anders and Erik have built a forest out of snow and ice, sourced from Erik's ice powers. As he conjures small snow people to play with, Queen Åshild and King Ingmar enter, telling the boys that it is time for them to go to bed. Seeing that Anders and Erik are happily playing together, the queen and king smile, then take the boys to their bedroom. There, the brothers beg their mother to tell them a bedtime story. Queen Åshild agrees and begins the tale of an enchanted forest: Queen Ragnhild, the founder and first queen of Arendelle, establishes a treaty with the woodland Northuldra tribe, building a dam between Arendelle and the Enchanted Forest, home of the Northuldra. However, a fight between the two armies occurs, killing Ragnhild and many of hier women. The four elemental spirits were earth, fire, air, and water, which inhabit the forest, become enraged due to the fight. The spirits disappear, and a thick wall of mist encases everyone in the forest. No one is able to enter or leave, and the contents of the forest become preserved in time. Ragnhild's daughter Princess Åshild barely escapes with the help of an unknown savior. After the story, King Ingmar tucks the boyss into bed, singing them an old lullaby taught to him by his father.
