We explored the apparent life cycle of the naaru in a recent Know Your Lore, and considered the possibility that perhaps naaru regeneration -- the rebirth of the naaru, after they have been damaged -- depends on the Light. If the Light is being practiced, or if those dead souls are the souls of those who have given themselves over to the Light, this seems to be the case. If the souls are not Light-practicing creatures, as with the case of K'ure and the souls of orc ancestors in Oshu'gun, then the naaru neither regenerates nor falls completely into the void, simply fading away over time. Prophet Velen sacrificed his own life to jump-start a naaru back to health in Shadowmoon Valley -- how he was able to do so hasn't been clearly defined.
But the question then becomes: Did the naaru teach the draenei the way of the Light in order to recruit them into an Army of Light? Or did they teach the draenei the Light in an effort to bolster their forces and provide some kind of insurance in the event that one of their dwindling numbers happened to fall? Not as an act of malevolence, simply a clinical action designed to bolster the dwindling numbers of an alien species we don't comprehend. In exchange for our subservience to the Light, we get the powers associated with it.
Are there two parts to the Army of Light? Obviously yes, there is an aspect in which we are expected to fight the Burning Legion and win, the naaru seem set on that just as single-mindedly as Sylvanas was set on seeing the Lich King destroyed. But are we also tools for the naaru, insurance in the event that one of them is slain, a method to prevent them from descending wholly into the void and instead, in an extreme twist of fate, save themselves from certain destruction? Does our practice of the Light merely inspire hope, benevolence and warmth within those around us -- or is it also a lifeline for a species we hardly know and barely understand?
