Frozen III (Fanmade)

Questions from (Frozen II)

1. How did Kristoff know about Northuldra.
(In the scene where Elsa had defeated storm, multiple statues were formed; there was a statue of a girl saving Elsa & Anna's father was formed.
Seeing the girl, Kristoff told the identity of the girl but how he knew.
It may be he had heard about their stories or he was a part of them who had escaped like Elsa & Anna's father and mother or from the trolls so seeing her, he identified)

2. There was a man to whom Elsa & Anna's grandfather told his plan.
(In the scene, in the ice world, there was a vision, in which he was telling his plans to the man. It can be that the man was a evil Northundra and he manipulated some vision or Elsa & Anna's grandfather was under the man's control and when he realised it he beheaded the man not the Northundra leader and the man maybe be Elsa & Anna's grand uncle)

3. When Elsa was trapped and fighting of storm, she saw some visions in it. There was a vision in which a man was beheaded by Elsa & Anna's grandfather; who it was (the man with whom he was plotting in the Ahtohallan scene see point 2 for further detail) or Northundra leader.

4. The Northundra old lady said the nature would not give power to any person in Arendelle, why?
(In the scene where she saw Elsa & Anna. Sometimes, mysteries of present lies in the past. Even the elder troll asked whether it is curse or boon. The Northundra people mentioned they are people of Sun.
They said it because maybe a Northundra person married a Arendelle Queen or King or a Northundra person made Arendelle and misused it's power and ended up being cursed. See point 2,3 to understand better.)

5. Water remembers everything, so Olaf is made of water, so remembers something of past.
(In the scene where Elsa sends Anna & Olaf away,  Olaf says that his anger was growing,  maybe he remembered some betrayal scene which brought him anger.)

6. The flag of Arendelle, there may be some story of past.

7. Whether a third sequel will be made or not.
(Assumption being made) Past of enchanted forest & Northuldra or Trolls in danger or formation of Arendelle or Past of Ahtohallan river and it's formation.

8. The fifth element was love.
Love between two sisters.

9. (Assumption third sequel being made) If trolls in danger,  their main energy source is lost and Kristoff is troll guardian. The team adventure to get back with troll energy source.

10. (Assumption third sequel being made) Story of Sun people and moon people and earth people and air people and wood people and metal people and fire people and water people. And one more banned people  (controller of life and death) and their connection with Ahtohallan river. Anna being moon and Elsa being sun or Anna with dark powers and Elsa with bright powers.

11. (Assumption third sequel being made) Story of founder of Arendelle and  formation of Arendelle.

12. (Assumption third sequel being made) Past story of Ahtohallan river.

13. Does Olaf has some memories of past of the dam, before the fog, had there been ice monsters before fog,
(In the scene where all ice statues were enlightened even Olaf was shining may be he had some memories of past because 'water remembers everything' so Olaf is made of water.So, he may have some memories of past before fog. Also see points 1,2,3,4,5,6,7,10,11,12 for understanding this point better. )

14.  Elsa & Anna's father and mother were drowned in the water so they may be alive because their mother was a past Northuldran which means she might have saved their father like she saved him earlier.
Their parents are not dead nor their grandfather because he had fallen from the cliff ; their parents might be trapped somewhere.

15. Then there will be question who will rule Arendelle,  Anna or Elsa.
Elsa once started endless winters , she angered the elements which led the people to leave their homes, she put her family and Arendelle in danger;  Anna will support her claim to the throne but some will support Hans claim.
Some will support Hans marriage with Anna while some will support Kristoff marriage with Anna.
Elsa & Anna's grandfather will support Hans and blackmail Anna by keeping their parents as captives.
To save them, Anna will play as she is with Hans and greedy for throne but deep down she is helping Elsa in disguise leading her to their parents and then the old secret is out that
Even Elsa & Anna's grandfather is Northuldran but also an Arendellen.
And his wife was a troll guardian.
So, their father was troll guardian.
And Ancient Northuldrans had build Arendelle but some misused their power and lost power. Some assumed that never a Arendellen will be chosen for power but reality was if someone gets powers & uses it for evil ; their power will be lost whether it be tribe people or Arendellen.
Then
(In the Ahtohallan scene, the king of Arendelle and a man is talking about plot against Northuldra, their grandfather is that man and the king is his brother so, he had adopted Elsa & Anna's father as his foster son; deep down he wanted to be God.
So, he asked elder Northuldrans but they disagreed, so in revenge he build dam but lied Elsa & Anna's father's father and when he knew, he tried to stop the king but they fell off of the cliff and Elsa & Anna's father was calling his real father, he knew about it because the king adopted him at that age. The king had lost his path so he lost his powers, he could get powers back by the bond of Anna & Elsa but instead he gets defeated in the end because Anna had found the solution by Eldest Troll that Olaf is the elements guardian)
(so their bond power gets diverted by their father & mother and he becomes a giant snowman with a ice robe and a wand with Anna & Elsa, Kristoff and Sven shaped diamond on top)
And at last, Elsa & Anna's father and mother takes throne .Elsa & Anna both will be the heir . Anna & Kristoff gets married.
