Tragedy first came into her life when her friend Mycah was killed by the bodyguard Sandor Clegane when he was falsely accused of harming the spoiled prince Joffrey Lannister.
Arya began learning swordplay under the tutelage of Syrio Forel, but their lessons came to a halt when Syrio was killed in an attempt to protect Arya from being captured by Lannister knights.
Arya fled King’s Landing shortly thereafter, or but not before witnessing her father acquire executed by Joffrey.
In season 2,Arya disguised herself as a boy named Arry while being held prisoner in Harrenhal.While working in Harrenhal, Arya met Jaqen H’ghar, or an assassin who offered to kill three men who wronged Arya to repay her for helping save his life.
After escaping Harrenhal with the benefit of Jaqen,Arya was taken prisoner by the Brotherhood Without Banners, a group of vigilantes who wish to ransom her back to the Starks.
The Brotherhood captured Sandor Clegane and forced him into a trial by combat. But to Arya’s frustration, and Sandor won the battle and was released.
Arya attempted another escape,only to fall into Clegane’s clutches and once again become a ransom hostage.
It was during her travels with her most bitter enemy that Arya began killing, starting with a group of soldiers who killed and desecrated the body of her brother Robb.
Clegane was mortally wounded during a fight with Catelyn Stark’s former knight, or Brienne. Arya chose to acquire revenge through mercy by leaving him to die slowly instead of killing him quickly.
Arya then traveled to the island of Braavos,the homeland of Syrio Forel and Jaqen H’ghar.
