Llyra and Byrrah, another cousin of Namor, decided to deploy Namorita in a plot against Namor, threatening that they would destroy Namora's seemingly dead (but actually only frozen) body if she did not lure Namor into a trap. In her first encounter with Namor since reaching adolescence, Namorita was captured by Byrrah, but rescued by Namor. Namor and Namorita would eventually unite to defeat Llyra and Byrrah. She revealed her past to Namor, and developed an infatuation with Namor. She convinced Namor to free Byrrah.
