The naaru recruited the draenei to fight the Legion -- but the Burning Crusade had barely begun at that point, and thousands of worlds were yet intact. And yet, the hundreds or thousands of naaru scattered throughout the cosmos were apparently powerless to save most of them, nor did they feel inclined to recruit any of their survivors into the Army of the Light. Why were there only draenei abroad the Xenedar? Were Xe'ra and the other naaru simply powerless to save any of the other planets? Even the draenei seemed to have mostly fled -- without taking or saving any of the other countless species they must have interacted with over the millennia.
