When i got to the North pole i was stopped by the guards of the northern water tribe. They asked what i was here for as i was visiting them as an outsider during war time. I answered by telling i was coming to learn from their waterbending masters. They arrested as i let them and led me to their patriarch. He asked where i was from and i told him my story and my inheritance of the southern water tribe. He was still suspicious of me until i showed him an improvosed move of mine called: Mist Bomb where i instantly boil the water into mist and freeze it right after making the change of temprature causing a explosion.
As my technique impressed Arnook he wanted me to join Pakku as his student.

After a few days i managed to learn every technique of Pakku impressing him and Arnook which allowed me to enter the healing studies of Yagoda a privilege never given to a man vefore as this was the waterbending taught to women. I spent no time learning them as i had created the spiritual being skill granting me the ability to use chi to heal.
Because of me mastering the techniques i quickly became known as the prodigy of the south as i was the only waterbender of south and i became the only waterbender to be better than Pakku. Because i had nothing more to learn from Pakku was made the bodyguard of Yue so she could have someone her own age to talk to, even though Arnook said that i knew he wanted us to have a relaationship to strengthen the bond between the tribes. As time went me and Yue had a great freiendship i often teased her and flirtes with her, but nothing happened. Until we went to swim as she saw my body for the first time. She started bleeding from the nose and ran out. After that incident she started to avoid me and became touchy while i was on duty. Because of her father knowing about her affection towards me the engagement between her and Hahn never happened.
My life went like that for a few weeks until the day the Avatar came. When i was on duty guarding Yue i bended the boat around the canals of the city we saw the flying bison of the avatar. Later that day we had a feast in honor of the Avatar. I and Yue sat together with Team Avatar. While Sokka tried to flirt with Yue i sat down next to Katara and asked her -The girls from the south must be beautiful if they all look like you. I'm Sifan what's your name?-. Causing her to say -Kat....Katara- While blushing. Saying that caused her to have a good first impression of me. We countinued to talk with each other until Yue jealously tried to take me away after leaving Sokka with a sobbing face when saying she liked someone else.
The next day i was off duty and was having a spar with Pakku as he was the only waterbender i knew who could give me a little challenge. While fighting he sent a tidal wave towards me breaking the ice on it's way as it got closer i split his wave in two and solidified it into ice. I condensed the massive ice into two swords and went on a relentless assault. Causing him to back off and losing control of the fight. My strikes were full of feints to bait attacks from him. Whe raisee his arms which made an enormous wall of water to create distance between us. I made my swords into a wave to ride it over his wall. While midair i condesed water particles in front of my knuckles and punched down towards him. He dodged, but the place where he stood and the rest of the battlefields ice dishelved into pieces. I bended the ice into spikes and trapped Pakku in them while immobilizing his arms.
He sighed and said -Sifan Your fighting style is too unpredictable for me. I think i'm getting old-.
I released him from the ice and turned around too leave but was stormed by an excited tatooed bald kid. He sprung up right in my face and shouted -I've never seen someone waterbend like that. It was AWESOME!-. He then went on to do a very bad mimicing of my technique.
When he was finished my eyes landed on Katara as this was the moment she would rejected by Pakku. After he told her no she went on a rant and then left to go learn healing.

The day after The fight between Katara and Pakku i went to watch the training of Aang and Katara. When i saw how they progressed i got impressed as Katara had almost become a master in the short timespan. Pakku praised Katara and said -Katara i'm impressed. You're the second best student i ever had-. This made her have a questioning face and asked curiously -Who's the best then-. He answered while pointing at me -Sifan, he is the only waterbender i know that's more powerful than me-. Katara's mind wandered to a handsome guy at the feast. She blushed and tried to challenge me, but when she was about to ask me black snow began to fall down.
The fleet of Admiral Zhao is coming. And the siege of the North Pole has begun.
