Chapter 1

A small ship was approaching Republic City. Its crew was small, and besides the sailors, consisted of only three human passengers, a reindeer, and a talking snowman. "Elsa, we are finally here," spoke Anna as she hugged her sister.

"I know. The attack on Arendale was unexpected. Fortunately, we have an Uncle here, who judging my mama's stories was quite an inventor. Don't worry Anna, we will get Arendale back from this so called Northern Water Tribe," spoke Elsa as the ship docked.

"Your Majesty," spoke Kristoff as Elsa lightly glared at him.

"Elsa, you can call me by name Kristoff. You helped saved Anna. Besides, you two are courting, and you will perhaps become my brother in law one day. So, it's Elsa," smiled Elsa as the three humans arrived on the docks.

"I will wait here," replied Kristoff as Elsa nodded, and two sisters entered the city.

The two sisters walked in the Republic City, being amazed to see a place where many people could control an element. In her early years, Elsa thought she was the only person who could do magic, but apparently there were thousands of people who could control one of the four elements.

Elsa saw that three small kids were playing with their respective elements. "Elsa, this is so nice. There are many people here who can do magic here. Do you think they want to build a snowman? I am sure Olaf would like some company," smiled Anna

Elsa looked around and finally spotted a police car. "Wait here Anna, I need to talk to this police officer. I hope he could help us find where out Uncle is," spoke Elsa as she approached a young police officer.

"Excuse me, could you tell me where I could find Hiroshi Sato? My sister and I wish to speak with our Uncle," spoke Elsa as he young man panicked.

"This is Mako, requesting backup," spoke Mako as he formed some fire, in order to intimidate Elsa.

"Now, now, don't do anything stupid, come with the police for the questioning," spoke Mako as Elsa opened her eyes widely, and then shot snow at Mako.

"Why would a Water Bender want to speak with Asami's dad?" though confused Mako as he retaliated, and sent fire at Elsa, who extended her hand. The weather on the street got much colder, which also extinguished the fire. With another hand movement, Elsa sent ice at Mako, trapping him in a block of ice, so that only his head would be visible.

"Elsa," spoke Anna as she ran towards her sister.

"Don't worry Anna, I did not send ice in his heart. I only trapped him in the ice," reassured Elsa her sister before she felt a metal cable on her arm.

"This is police. Stand down," spoke a Metal bender, as more metal ropes flew at both Elsa and Anna, quickly tying both sisters. Another Metal bender formed two metal claws, and freed Mako.

"Elsa?" asked Anna but her sister was not sure what to do yet. She knew she could just freeze all of these officers by creating ice statutes, but she knew that these men and women were only doing their job, and unlike the Northern Water Tribe soldiers, these people had no malicious intent.

"Let's play along," spoke Elsa as Anna nodded. The officers brought the two sisters to police HQ.

Later, both Elsa and Anna were sitting in an interrogation room, with their hands tied with metal cables. Anna looked worried, but Elsa tried to keep an appearance of being calm. The Queen hoped that there was just a big misunderstanding, and that once the officers would now about her situation, they would let the sisters go.

A woman in her fifties arrived in the room. "Who are you? Why did you arrive to Republic City? More importantly, why did you wish to speak with Hiroshi Sato and why did have you attacked one of my officers?" spoke the woman.

"I am sorry for misunderstanding but my Kingdom was attacked and annexed by the Northern Water Tribe. I wanted to get help from our only living relative, Hiroshi Sato," spoke Elsa

"Likely story. Kids would make anything up these days to get themselves out of trouble," spoke Lin as Elsa looked on the table. She sighed, while this woman was not malicious towards her, she did not seem to believe her story.

"Luckily for you, the officer who you attacked called someone to help the interrogation," spoke Lin as a group of people entered the room. Elsa recognized the Fire Bender officer who she briefly fought before.

"Who are you? Talk?" spoke Korra as she approached Elsa and glared at her.

"Korra, I think I should talk to her," spoke Asami as she looked at her friend who nodded.

Asami approached Elsa, and sat in front of her. "Mako told me that you wanted to speak with my Dad," spoke Asami

"Your what?" spoke Anna

"Hiroshi Sato is our Uncle. My mother, Queen Idun was his sister. Would it be possible to speak with him? I need help. My country was annexed and conquered by the Northern Water Tribe," spoke Elsa

"Wait a second, did you say Idun? I remember Dad told me he had a sister with name Idun, but the two separated early in life when she decided to go live in some small kingdom in the North," spoke Asami

"Oh, that's great. See Korra, Asami and this young lovely lady are cousins," smiled Bolin

"Chief Bei Fong, could you release them?" asked Asami as Lin sighed, and made a hand gesture. The metal handcuffs opened.

"I did not know I had a cousin," spoke Asami

"Two actually. Anna is my younger sister," corrected her Elsa

Asami smiled. She approached the two women and hugged them, "Come, let's discuss your problems during dinner," spoke Asami as the two sisters followed the heiress.

"Sorry for before. My name is Avatar Korra. I can bend all four elements," smiled the Avatar.

"Elsa can use ice magic," spoke Anna

"Magic? I think you mean Water Bending," spoke Korra

"Hey guys, I am sorry to ditch you, but Fire Ferrets will have a match in the next hour, and I need to help my team to prepare for the match," spoke Bolin as she left the group.

"Me too. I just received a message that there was a robbery on the fourth," spoke Mako as he also left. After the two brothers left, Asami looked at the remaining group.

"So, who would like to eat at Kwong's Cuisine?" asked Asami as the four young women journeyed to the restaurant to discuss Elsa and Anna's problem.

A/N: seeing that there are only 3 other Korra/Frozen crossovers, and the fact that such a crossover has so much potential, I decided to write one myself. This fanfic starts at the beginning of book 2. To clear some confusion, Arendale monarchy is not related to the Northern Water Tribe one. Arendale is a small Kingdom that became autonomous from Northern Water Tribe.
