If the Tears of Elune hint is anything, it is possible that countless cycles of creation have existed, and Naaru are one of the oldest surviving embodiment's of the light still serving in this cosmic war with the void. Maybe Elune really did create the Naaru before time, and Xe'ra still continued her service under mandates that predate this existence, and as such, took more blunt approaches to achieve her goals.
Either case, she and her line are officially dead now. Until more light (no pun intended) is shown upon what they accomplished we wont know what has been hidden until much later.
