Khart was a Hvetshran male who lived in the tenth century. He was a son of the clan leader of Sthn. Since the female Shyar however was the most adequate clan member, Khart as her friend decided to step forward to propose to her, which most likely was the decisive element that played in the clan elders' choice when succession became an issue.
When Shyar got an eye on Xyuln, Khart knew that he would not be able to oppose her decision to marry him as well, but gave her the only condition that she would have to give him a child first, which she did. For most of Shyar's reign, Khart was married to Shyar and Xyuln, who both outlived him.
