On the planet Thra, three Gelflings—Rian, Brea, and Deet—inspire a rebellion after discovering a horrifying secret behind their customarily worshipped rulers, the Skeksis, that threatens their entire planet. This is Katavra’s sword, her main weapon through Dark Crystal. She is a Gelfling princess of the Vapra Clan and the middle daughter of All-Maudra Mayrin and the middle sister of Seladon and Brea.
