Born during the pacifist age of Mandalore, Charon Kharn was anything but peaceful. Even as a toddler, she had a fairly destructive streak, as well as a penchant to fight anyone that came at her. She would win every fight she would get into, easily. It wasn't until she was 5 years old, that it would be discovered that she was Force Sensitive. When discovered, the Jedi who had come to Mandalore took the child to join the ranks of the many apprentices. Her family allowed this, thinking that it would temper her destructive nature, and teach her control.
For the next five Years, even through the events of the clone wars, she trained in the ways of the Jedi, only becoming a Padawan at the age of ten, when she was deemed ready to go under a master. Her master, Shrassarri Kadeeli, a relatively new Togruta master, didn't believe in the war, and took her to a remote planet to continue her training.
Unbeknownst to the two of them, this would allow them to escape the events of order 66. After the Clone Wars had ended the two remained on the planet in order to hide from the galaxy, fearing whatever it was that caused the mass genocide of the jedi order.
For the next 14 years, Charon would dedicate herself to learning the Juyo dueling style as well as the Steel hand martial arts, in the event that she would be caught without a lightsaber. Believing herself to be incredibly powerful, she asked her master to allow her to leave and refine her skills in true combat.
Master Kadeeli had left the planet many times in the 14 years, and learned of the new galactic empire, as well as the events of order 66, and the outlawing of Jedi. In order to protect Charon, she told her that she was safer on the planet, and forbade her from leaving.
That was until the Empire came. One of the merchants that Master Kadeeli had interacted with suspected her of being a Jedi, and slipped a tracking beacon into her supplies and sold her out to the Empire. In order to protect Charon, she told her to leave and hide somewhere in the outer rim, while she held the inquisitors that had come to the planet off.
Charon protested, and wanted to fight alongside her master, but Kadeeli told her that she wasn't meant to die here, and to become stronger. Charon relented and left, and left for the outer rim, but instead of going to a remote planet, she went to Mandalore, her homeworld.
Charon saw what happened to the world she used to dream of returning to as a fully fledged jedi, and cursed the empire, swearing that she would destroy it so that she could return it to it's former glory. It wasn't long after that that she came into contact with the Rebel Alliance.
