Frozen: Fire and ice

What if Anna and Elsa had powers? What would be the same? What would be different? Anna and Elsa find Anna's birth certificate. They go on a quest to find out who they really are. They meet some friends along the way. This is my version of frozen. ( This is my first fanfic, please don't judge.) Please review if you like the story, have a suggestion, or if you have any objection.
