Waterlight is a young Wraith Queen.
She does not have many fighters and Queen Death is a big problem for her. But Teyla Emmagan, disguised as Steelflower, convinces her to oppose the queen and to fight against her together. In the final battle, her father dies in a confrontation with Ashes, but her alliance with Steelflower and Alabaster remains even after Waterlight learns Steelflower's true identity, focusing on Teyla's shared heritage with the Wraith Queen Osprey rather than her primarily human biology. To maintain the secret of Teyla's heritage, Teyla allows the other Wraith to believe that Waterlight killed Queen Death rather than herself.
