Sunset Shimmer a Narcore, a passive near human species who dedicate their lives to living natural pure lives without medical interference. Since birth, Sunset suffered from a spinal deformation. Many were surprised that she survived for so long with the lack of medical treatment. Though one day she had fallen and sustained injury that could’ve prove to be fatal. Her soon to be master had heard her cry through the force and sensed her will to live. He arrived and offered her tribe a chance to save her, though skeptical at first her elders were reluctant to allow her to seek medical help. She had made an astounding recovery and swore her life to the way of the force. In a matter of years she had proven her self to be a capable leader, strong instincts and stunning reflexes despite her disability.
 
Though a running concern worried the counsel and her master. She felt it her obligation to interfere in many predicaments where Jedi were not needed. Using her personal experience as means to justify her intervention. This placed her in long probation period under her master’s watch. During a routine assignment, they were present at a treaty signing as a show of good faith. Though a conflict escalated and her master attempted diplomacy but Sunset took the situation into her own hands. Instigating a fight she knew she would win, she achieved “peace” through silence of the opposition. This completely caught her master off guard, during the confusion and with one calculated strike she executed her master. From then on she formulated that sometimes peace can only be achieved through bloodshed and that universe would benefit from the interference of the force.
 
Since her fall and study of the Sith ways as Darth Odium, the device supporting her spine and neck had began to be rejected from her body. A more stable but abrasive device was implanted but it impaired her movement and flexibly. Through rigorous training she found way around her handicap and developed a style, a variation of form VI using her force powers to make up for lack of her mobility.
