Hey guy's this is my first Frozen/ROTG fanfic and don't judge me if the characters are off. I've seen Frozen three times and ROTG once so the Frozen characters are gonna be better. The pairings will be Jelsa & Kristanna. The title is Norwegian because thats what Frozen was and it translates if you put it into google translate to Tribulations of the Strong.

Disclaimer I do not own the characters except for the OC's, the rest belong to Disney and Dreamworks

Chapter 1: Proleague

In the lands of the north there were two kingdoms, one that was celebrating happiness and one that was in despair. The happy kingdom of Arendelle was celebrating the engagement of their princess. Everywhere in the streets were rejoicing about the happiness that fell upon the kingdom in the last year. First of the new Queen who, even though caused a winter to appear in summer, was crowned and saved the kingdom, and of the princess and the royal ice master and deliverer who's marriage they will be celebrating. In the kingdom of Isengaard the people are in despair and the sons of the king are by his bedside, awaiting his health to improve.

"Father, we're here," the eldest said.

"Bunnymund? Jack?" the old king asked. The eldest, Bunnymund, nodded his head.

"Yes father," Jack said. The old king smiled, his breath weak, and looked to his eldest.

"Bunnymund, my son, these are my final minuets," he said. Bunnymund looked down and took his fathers hand. "You will take my place on the throne and lead Isengaard, and Jack, don't be afraid of your gift," the old king said. Both Jack and Bunnymund looked down with tears in their eyes. The king took his last breath. "Stay strong, my sons," he said, and the old king let out his last breath and layed still unmoving for the last time.

"Father," Bunnymund said in sadness. He looked down and prepared for what he had to do. "Jack," he said to his younger brother.

"Yes?" Jack asked.

"Go get Pitch and leave us to talk," Bunnymund told him. Jack looked at him and bowed and left to go find the royal adviser. Jack found him and called his name. Pitch turned around and Jack explained that Bunnymund needed to talk to him. Pitch walked in and the new young king looked up. "My father passed and I need you to help me figure out what to do," he explained. Pitch smiled, he never liked the royal family and always tried to make the king go down the wrong path but the old fool King North never did, but now that the prince was king he had a chance of ruining Isengaard.

"It must be obvious your majesty," Pitch said. Bunnymund just looked at him in confusion. "Last year after all the lands were covered in snow the sickness came and effected our kingdom, and who was responsible for the snow," he said, Bunnymund looked at him with realization. Pitch smiled as he saw the young kings face turn into anger.

"Write down everything I say and put it on record," he said, Pitch nodded and grabbed a quill and paper and nodded at the king. "Let it be known that on this day I, King Bunnymund Frost of Isengaard, assume the throne with a heavy heart and from this day forward declare war personally on the kingdom of Arendelle and Queen Elsa herself," he said. Pitch smiled as he finished writing it. "Send it out to Arendelle and make sure it arrives on the wedding day of Princess Anna and Sir Kristoff,'' he said.

"At once your majesty," Pitch said and cracked an evil smile. Pitch then made his way to the guardsmen and handed the letter to the captain and relayed the message to him and he nodded and set out with three men to Arendelle.

I know guys I'm sorry to leave it on a cliffhanger but I just can't fit anything more into this chapter. So next chapter is Anna and Kristoff's wedding and the message arrives to Arendelle, how will that change the mood of the kingdom? How will Elsa take the news of war threatening her kingdom? You'll just have to wait till next time ;-)
