Introduction to Princess Elsa

Princess Elsa (Elsa), the heroine in the Disney animated film "Frozen" and its derivative works. Anna's sister, the eldest princess of the Kingdom of Arendelle. Princess Elsa looks noble and elegant, cold and reclusive, but in fact she has been living in fear, trying hard to hide a big secret, and struggling with powerful secrets in her heart. She is born with the magical power to summon the wind and snow. The ability is beautiful, but also extremely dangerous.

Because her magic almost killed her sister Anna when she was a child, Elsa has closed her heart and isolated herself, always trying to suppress her growing magic. An accident at the coronation ceremony caused her magic to go out of control, causing the kingdom to be covered in ice and snow. Fearing that her magic would get out of hand again, she fled into the snowy mountains and used her magic to create a castle.
