Wungi is the daughter of the Chieftain of the "Evge Mum" (or Katarn Claw) tribe. They are famous throughout Kashyyyk for taming the wild Katarn and riding it into battle. From an early age she was captivated by the dangerous and majestic beast and wanted to ride it into battle with the elite Katarn Riders. Traditions would say otherwise however, and she would be forbidden to join the male only warrior class, and instead prepare for marriage.
She tried hard to resist this tradition, placating her handlers during the day, and discretely researching everything she could about the wild Katarn at night. Her father didn't have the heart to tell her it was not possible, and provided even secret tribal knowledge of the traditional method with which a Katarn Rider needed to track, tame and train the beasts to become a successful team.
As she approached her 12th life day, she pleaded with her father and anyone else who would listen to remove the male only requirement for the hrrtayyk Test of Ascension and the ability to be a warrior. This act of dissent brought her before the leadership council where her father was required to publicly reprimand her for causing such a stir within the tribe.
She left that meeting so distraught at her father's rebuttal that before he could return she had gathered a few supplies and left. Telling no one of her plans, she would secretly perform her own Test of Ascension and return with a Katarn mount. The tribe would only be able to marvel at how she could accomplish such an amazing task and surely invite her to be a part of the Riders.
The hunt for a Katarn was more difficult than anything she had imagined. She wasn't so naive to think one would walk up to her and submit, but she had lost track of how long she had been on the trail. Her latest quarry seemed to be playing with her, and she was exhausted. The books taught techniques and theory but not how to adapt or prepare for this. As she sat high up in the trees and accepted her defeat, she began to sing. It was a turn her mom had taught her when she was little and it was meant to soothe and relax. She soon fell fast asleep.
When Wungi returned to the tribe, it was not with celebration, but of anger. She was a natural leader, and the tribe council saw a threat to their traditions and power. They exiled her, and made her father deliver the message in front of the whole tribe. Before being sent away in shame with only what she was carrying, her father spoke of her greatness and that he was sorry that he had failed her. He gifted her with his ancestral Katarn Claw, which he had attached to a necklace and put it over her head. With that act, the tribe turned away from her, and she was on her own.
Inspired by her leadership, or tired of the old traditions, many left with her. Uprooting their lives to form a new tribe, a new family. The new tribe was called "Tobuck Evge" or Song of the Katarn. They had a hard life ahead of them. They had left the safety and knowledge of the old tribe to start anew.
The new tribe was not out on their own for long before they fell victim to Imperial supported Trandoshan slavers. The commander of the Imperial ISD in charge of organic resource procurement wanted a trophy, and what would be a better way to show your superiority than to have a Wookie as a servant. He purchased Wungi, and the surviving tribe as well for incentive for her to behave. She knew their pain was her fault and she would do what it took to protect them and find a way to get back home.
Teaching his new prize how to be a domesticated servant, Captain Chova Zenn was proud of his new prize. While she was not accustomed to the hard labor of the tasks, she was familiar enough with the roles she was learning and was a quick study. It was her knowledge of language that provided the spark she needed to escape.
She was serving the Captain a meal with the leaders of the Slavers when she overheard them talking about her in their native tongue. There was nothing new about their view about her, except when they dropped that it was a shame the rest of her people we too weak to be slaves and had to be killed.
Enraged by the news of her family's demise, she broke free from her binders using her Katarn Claw necklace, and tore through the ship's security personnel and the Trandoshan guests. She was fortunate to time her escape with an attack by the Han Solo and Chebacca led task force to free the Wookie people. As she flew off the hanger deck of the ISD Predator, she could see the incoming fighters and took solace in the fact that they would pay for what they did.
