|Chronological and political information|
During the war between the Republic and the Sith Empire, Sophia became a noble friend to Gaden-Ko, a Mystic in training. She eventually helped Barsen'thor when the young Jedi Consular arrived on Voss in search of alliance against the Empire and suggested that the Barsen'thor helped her friend Gaden-Ko in his training to gain the trust of the Voss. However, when Gaden-Ko came back with Barsen'thor to ally with the Republic, Sophia revealed to be a child of the Sith Emperor.
With two Sith acolytes by her side, Gaden-Ko had no idea why she betrayed him and the Jedi, but she told him not to worry and that his true destiny is just the beginning. She and the acolytes engage Barsen'thor, but the Jedi took the upper hand and defeated them in combat. Sophia was wounded and was surprised how the strong the Jedi was in the light side. As a child, she believed that the dark side was the true power. She revealed to Barsen'thor that she was pilgrimaged to test Gaden-Ko's power under the instruction by the First Son, the first of the Emperor's children. She feared that the First Son will kill her for her failure, but Barsen'thor believed that he can save her from the Child's wrath and letting go of the dark side.
After slowly fading from the dark side, she explained to the Jedi about the First Son who serves the Emperor, but Gaden-Ko was so upset that his own friend betrayed him. Sophia apologized for her actions since she wanted to save him and allow the people of Voss to serve the Emperor and Sith Empire. She was taken into custody by the Voss officers and would eventually be sentenced to death. Sophia decided that it was best to take her responsibilities from her actions and was taken away.
