5 years passed sense the events of the second film, Anna is now queen of Arendelle and Elsa has become the fifth spirit of the Enchanted Forest where things have been peaceful lately as for Elsa she often times worries herself as to what unexpected threats will appear to attack the forest while Anna pays her a visit and discuss some future plans to expand the kingdom outside of the forest, but Elsa dismisses her offer cause that doesn’t sound like the spirits would approve it and as to why Anna is somewhat desperate to stay close to her sister at any cost so that she wouldn’t loose her again like last time. Elsa storms out and takes a moment to be alone in the snowy woods where she heard the voice telling her that someone has trespassing the forest, she investigates without Anna’s help and she found a person wounded in the shadows that left literally foot prints made of ice that is impossible for her to believe that someone possessed the same magic as her’s. Elsa confronted the wounded icy man who’s afraid at first but seeing her beauty makes him curious and shows Elsa his magic like nothing she’d seen before, the man was named Anderson who is wearing damaged armored made out of ice and somehow can hear the voice too so Elsa was grateful to help him out to confront the spirits if they approved his presence in the forest and her sister Anna along with her family Kristoff, Olaf, Mattias, and her 5 year old daughter Kristana came to join Elsa helping out Anderson.
Things are going smoothly for Anderson as he feels open minded and learned to let his guard down as Anna and her family left to give em boundaries Elsa sees that he has battle scars on his waist for knowing that he fought in a brutal battle with someone long ago. Anderson decided to explain Elsa that he’s been fighting a fiery conquerer named “Raseri” who gains a powerful sword that can burn or create anything under its image as he’s been hunting down Anderson for years for knowing the magic he’s born with and will stop at nothing to extinguish Anderson and his magic. Elsa was truly horrified for what he said to her and knowing that he couldn’t defeat Raseri on his own she’s determined to help him after expressing her feelings to him that he went threw the same trauma life then her, Anderson heard thunder and the sky turned red as Raseri has arrived at the forest which he panicked a bit and decided to lure him away from sensing any type of magic from the spirits and Elsa so he must leave to keep her safe and once he confronted Raseri he already noticed someone else has magic before he arrived and Anderson makes a sword out of ice and fights him one on one. Elsa swoops in and saves him but Raseri has her at the upper hand as his ship unleashed canons and catapults to reign fire all over the forest and destroyed the spirits with one slash from his fiery blade had weaken Elsa in the process.
After the fall out Anderson gets Elsa to safety Anna could’ve believed what has happened to the forest and what Raseri did to Elsa so she’s deeply depressed to help Anderson out and vanquished this maniac, but he refuses to have em help him cause the last time he got help from people the previous times they didn’t survive Raseri’s fury and watched em burn to death and he cannot let that happen to Elsa, Anna and her people like last time. Anderson kept hearing the voice and Elsa still wants to help him and maybe take him to Ahtohalla in hopes to revive the sprits with their core crystals that are stored away there so Anderson and Elsa venture to Ahtohalla where they’ll also find answers as to who this Raseri is and why he's really after their magic. Meanwhile Raseri located the abandoned shipwrecked where Anna & Elsa’s parents died and he recognized em in the form of ice like it was made by Elsa’s magic which he realizes that this was the moment he’d been waiting for, by seeking pure vengeance on the king and queen of Arendelle for banishing him as he found out their first child was born with magic and try to kill it, so now he left the forest and sets corse to the castle where Anna and her family are at their mercy to prepare for war against Raseri while Elsa and Anderson are at Ahtohallan finding out the truth that Raseri was the man that set the events in motion as he manipulated king Runeard into believing the Northuldrains are too powerful and makes him and his kingdom weaker by comparison and after the mist emerges he took in the young Agnarr and over the years passed he fell for a Northuldrain as his queen Iduna and when Elsa was born she’s already born with magic and Raseri failed to extinguish her as the king and queen banished him and never to return. Elsa was in shocked for finding out that what he try to do as for Anderson he also found out that Raseri sensed his magic long before he returned to Arendelle to unleash his full fury but he was occupied by Anderson for years lately as he destroyed his home and murdered his parents and his people feeling with so much rage he nearly crumpled Ahtohallan with his strength, Elsa couldn’t bear to leave him like this so she approached to him and needed her help to save her sister’s kingdom before it’s too late even if it comes at a cost for one of ‘em to survive while she confesses her love to Anderson that their magic are more powerful together. Back at the battle Arendelle has taken a huge hit that the castle has sunken into the waters by Raseri’s blade and continues to finish off the last remaining soldiers but he was eyeing Anna the most to see if she’s terrified by his fury and wanted to let her know that everything she’d had will be gone and burned to ashes and just when he’s about to execute her the blizzard appears and the spirits returned to their forms as Elsa and Anderson arrived with a Icy army to clash against Raseri and save Anna.
The battle rages on as Anderson rescues the people and helps out Kristoff and Mattias to fight off the last remain of Raseri’s fire troops while Elsa faces off Raseri in anyway she could to save Anna as they are out numbered but Anderson swoops in on time to make his last stand against Raseri with his full strength and courage by Elsa’s passion and love he’s willing to sacrifice himself to save the sisters and as he clashes his magic with Raseri’s fury and blown to pieces disappearing everything in sight while the blade sank into the waters and is long forgotten. Elsa and Anna look over the destructive aftermath of their beloved kingdom as it’s no more and can’t be rebuilt with this much damaged, then out of nowhere Anderson has awaken from the blast with the help by the spirits who are amazed at his bravery they’ve gave him another chance so that he can be with Elsa and help out what he can to secure the future of her sister’s kingdom so Elsa decided to agree with her offer and move the Arendellians to the enchanted forest where they’ll build a new Arendelle and thrived on a better future for both worlds so that the sisters now live closer then ever before and Anderson become the new fifth spirit along with Elsa as they became a icy dyad to become one with the forest and the spirits, though their story is at a close the next chapter of their life’s has only began…
THE END
