Jlin, the Warrior of Winter.

Lore: Ever since his childhood, Jlin has loved the winter. While everybody else was cooped up inside to wait out the cold, Jlin would be playing outside. He was considered to be weird among most of his friends.

     When Jlin was given the opportunity to travel to the Freljord, he was overjoyed. He left for the expedition after hastily packing his things. While traveling, Jlin became separated from the rest of the voyagers.He was lost in the frigid Freljord. Instead of fight the cold, he decided to embrace it, and soon he found himself able to control the cold, and managed to get back to his group. 

    Once he arrived back home, his parents were shocked. They were proud of him gaining the power, but they kicked him out because they could not bear the cold. Jlin wandered Runeterra, eventually making his way to the League of Legends.
