Into the Unknown (A Frozen Fanfic)

What if King Agnarr and Queen Iduna were still alive? And what is Elsa and Anna went with their parents on their voyage?

Agnarr and Iduna tried to hide where they were really headed, leading Elsa and Anna to stow away onboard. After a raging storm capsizes their boat, the family becomes shipped wrecked in the Enchanted Forest.

Elsa has been seeing things, hearing things. A voice that beckons her. In the Enchanted Forest, she discovers that the current fifth spirit is luring her into a trap; desperate for all the power.

Separated on their journey, Elsa finds time to bond with her mother, learning that Iduna was a previous fifth spirit. Now, they set out to find Ahtohallan and the secrets it holds while fighting off the fifth spirit that threatens them and holds a grudge against Iduna.

Anna is left behind with her father and the Northuldra who have thankfully rescued them. She learns from their leader, Yelena, about the dam that is suppressing the four spirits power and Agnarr is more than eager to destroy it and free them. Anna, on the other hand, isn't so willing to let Arendelle be wiped off the map. But after a mysterious power takes ahold of Anna and turns her wicked, Arendelle is the last thing on her mind.

Will Elsa and Iduna succeed in freeing the vengeful fifth spirit, and can Anna hold back Agnarr from destroying the dam or will they all dive too deep?
