Rise of the Frozen Guardians
This story tells you how Jack and Elsa from Rise of the Guardians and Frozen can actually meet and stay together while making a balance in both of the worlds. If you have seen the movies, you probably would have found that Jack and Elsa are perfect for each other. Their ship is named Jelsa and is literally popular. My story is actually a theory that Dreamworks and Disney can use to make Jelsa canon.
In this story, Jack, Jamie and the Guardians goes to Arendelle through time travel caused by unknown reasons and Jack turns into human form and becomes 24 years old with minor appearance changes due to unknown reasons. There, Jack meets Elsa and the Guardians and Jack stays in the kingdom as Elsa invites them. Elsa and Jack spend many moments of fun together.
However, A new threat is waiting...............
