Riag'wug Vuwai was the daughter of Ra'uw'la Vuwai. She was determined to claim the Dimensional Weapon for the CLAW. During the Incident, she ran into Hequera, daughter of Ara'quera and spine of the Yiusha-Waalar. They allied together and fought Viper inside the Temple of the Beacon-to-call -the-Guardian. Riag'wug was injured by Viper and would have perished if she had not sacrificed herself to call for Hayelon to return.
