Once upon a time in the kingdom of Arendelle, there lived two sisters, Elsa and Anna. Elsa had magical powers to create snow and ice, but after an accident that almost hurt Anna, their parents decided to keep her powers a secret and taught her to conceal and control them.

As they grew older, their parents passed away and Elsa was set to become the queen of Arendelle. However, on the day of her coronation, she accidentally reveals her powers to the entire kingdom, causing chaos and fear among the people.

Anna pleads with her sister to come back and end the eternal winter, but Elsa is too afraid of hurting anyone again. In a fit of fear and anger, Elsa accidentally strikes Anna in the heart with her powers, freezing her heart and turning it to ice. To be continued….
