At a young age, Elsa realized that she holds an ancient ability over ice and snow, and often used her abilities to play with her younger sister Anna. Elsa shared a close bond with her free-spirited younger sibling, and the two were the best of friends. They often at night would make it snow in the royal ballroom. However, one night while the two were playing in the ballroom, Anna jumps down from the high snow slopes Elsa had created. Elsa tries to save her by using her magic, but accidentally strikes her sister instead. Their parents, the King and Queen, immediately seek aid for Anna by visiting the legendary trolls, whose leader, a shaman named Pabbie, is able to stabilize Anna's condition since it had only affected the head, not the heart, which would have been fatal. To be safe, Pabbie then removes Anna's knowledge and memories of magic, much to Elsa's despair. Pabbie takes the time to explain the true strength of Elsa's abilities, telling her that her power will only grow and there's not only beauty in it, but danger, and that she must learn to control them at all cost, or fear will be her enemy. While the King promises to help Elsa control her powers, the incident leaves Elsa traumatized by them. As a result, the King and Queen order the gates to be locked for Elsa and Anna's safety.
