Elsa has been feeling strange lately. She has always been different, she's always had powers. But she feels something slightly different lately.
She's been feeling strangely warm. Elsa knew that the cold never bothered her, but she assumed that was because of her ice powers. She assumed that she was immune to it. But granted, Elsa didn't know much about her powers, or where they came from.
That night, when Elsa was playing charades with her sister, her sister's boyfriend, and her son, Olaf, she was in front of a fire, and she didn't feel repelled by it. It was a new feeling. One she never felt from fire before. She felt strangely drawn to it. Like she wanted to learn its secrets.
And during Anna's birthday in the spring, Elsa was somehow able to create a new dress for both of them out of flowers and plants.
Elsa had no idea what this meant, but she knew her power was changing somehow. She could now do things that she was never able to do before. She thought she could just create ice, but she wasn't so sure anymore. She wanted to know what she was, why she could do this.
She's been hearing a voice that seemed to be calling to her. Elsa wanted to know what this meant. She wanted to find out what she was. What she was meant to become.
Elsa was trying to sleep, but she couldn't stop hearing the strange sound. It was like it was calling to her. And she wanted to find out why.
She got up and followed it. It led her outside. She sung with her powerful, siren-like voice that she was gifted with, something else that proved she was extremely powerful. She knew she wasn't a mere mortal. She was something far greater. And she was prepared to go into the unknown to find out what exactly she was.
