Sharad Hett was a Jedi who quit the order and made a home with the Tuskens. There, he married K'Sheek, a human woman who had been abducted by the Tuskens, and they fathered a son A'sharad Hett, who would later be taken as a Padawan by Ki-Adi Mundi, and even later go on to become the Sith Lord Darth Krayt.
