Naaru The naaru are a dimension - traveling race of sentient energy beings , with a deep affinity for the Holy Light of Creation that empowers the priests and paladins of Azeroth . The naaru blessed the draenei with this power in an effort to help them in their struggle . They are bent on stopping the Burning Legion . The name is pronounced [ ' na : ru ] . The plural is simply naaru . History . When Sargeras and the Burning Legion came to the world of Argus and began corrupting the eredar race , Velen , an eredar leader , prayed for help . The naaru appeared , offering to take Velen and any other like - minded eredar to safety . Velen and his faction accepted and began to call themselves draenei ( " Exiled Ones " ) . The draenei hastily escaped Argus aboard the Dimensional Ship provided for them by the naaru . During the draenei ' s journey , the enigmatic naaru race blessed them with Light - given knowledge and power . The naaru explained that there were other forces in the cosmos that would stand against the Burning Legion . One day the naaru would forge them into a single unstoppable army of the Light . Deeply affected by the naaru ' s words , the draenei vowed to honor the Light and uphold the naaru ' s altruistic ideals . Due to the interests of the Legion , and later certain Azerothians in Outland , the naaru moved Tempest Keep to Outland for a more direct observation . The Keep was stormed by the Blood Elves , but the sin ' dorei found only the naaru M ' uru within the ship . In Sunwell Plateau , Velen describes M ' uru ' s essence as " bathed by the light of Creation — just as it was at the Dawn [ sic ] . " This may indicate M ' uru ( and other naaru ) were born at the dawn of creation . In Wrath of the Lich King . The Naaru make an appearance in the quest , but otherwise do not play any major role in the " Wrath of the Lich King " expansion . Speculation . Technology . The dimensional fortress Tempest Keep , as well as the Draenei dimensional ship / city The Exodar , are examples of naaru technology . It appears that the naaru have advanced knowledge of magic and access to otherworldly materials and reagents that have not been seen in Azeroth . Tempest Keep looks much sleeker than most buildings seen on Azeroth ; however the texture slightly resembles that of " Wizard " architecture . The only factual knowledge we have is that Tempest Keep has " automated " defenses such as the ability to fly , and teleport itself and anything in it . It can be overwhelming to the lore considering that these features are usually attributed to the realm of science fiction , but if one looks at it logically it is not so technological after all . The automated defenses are most likely more powerful counterparts of the Arcane Towers built by the Kirin Tor . The Scourge ' s necropoli ( such as Naxxramas ) can also fly and move vast distances , so that ability can also be obtained through magic . In short , the goblins or the gnomes are more advanced than the naaru in terms of sheer technology . What the naaru use appear to be actual machines which are almost as advanced as that of the gnomes or goblins . But these are greatly enhanced by deep and powerful magic to the point where they give the illusion of being highly - advanced sci - fi technology . Or Naaru technology is so advanced it is indistinguishable from magic . It ' s the same sort of starships we ' re used to , but powered by the Light instead of nuclear fusion or matter annihilation . It is also worth noting that the Naaru may in fact be the most powerful " good " beings ever encountered in the Warcraft world . An example of this is a quest line where the player is tasked with finding a cure for the Scourge infection in a dying paladin . The player goes to the Nature spirits of the night elves and Alexstrasza , the aspect of life , who was empowered by the Titans themselves . The player journeys to each in turn to see if they can do anything to help him , but only the Naaru had the power to break the curse of the Scourge and save the paladin ' s soul . This could , however , also be caused by the Naaru and paladins both being followers of the Light , thus linking them to eachother . Biology . Naaru appear to be energy beings composed of shards of light that may freely move around a central " heart . " As such , they don ' t have a " biology " in the traditional sense . Perhaps they have a " lumenology " or whatever represents the workings of energy beings . It is unknown whether or not the naaru have separate genders . K ' ure , A ' dal , and M ' uru have all been described using the pronoun " he " , whereas K ' ara is referred to as " she " in the prophet ' s final message . However , the pronoun " it " has also been used . It is possible that the naaru are genderless , given that " gender " only exists in races that engage in sexual reproduction , and it is known that the Naaru were " born " at the dawn of creation via some other means . It appears to be possible for certain shattered fragments of a Naaru ' s body to still retain some essence of their being , as is the case with Light ' s Heart , the central core of Xe ' ra . Naaru are believed to be immortal . Darkened . If their physical form is damaged , it may bleed their energy causing them to enter a " diminished " or " darkened " state in which they are weakened and produce void energies . Their energy may take up to one thousand years to regenerate . It should be noted that some darkened naaru still appear to harbor altruistic intentions , however , their weakened state may be exploited for nefarious purposes , such as creating void minions . It is unknown if this cycle occurs naturally without an external catalyst . The known currently darkened naaru are D ' ore , M ' uru , and K ' ure . A naaru ' s darkened state is apparently different than death . Naaru may leave a " spark " when they die , as in the case of M ' uru . Dark or Light ? Some players have expressed suspicion of the perceived perfection and altruism of the naaru . Some believe that the naaru have ulterior motives , or there is an undiscovered faction of " dark " naaru . As D ' ore himself says , " " Without the void , the Light cannot exist . " " This could be taken to mean that if these Naaru are pure light and good , then there must be a polar opposite - that is , naaru or another race who are as much darkness and evil as the ones we have encountered so far are good and pure . It should be noted that although D ' ore is currently a darkened naaru , he appears to maintain good intentions . But there is also the possibility that his quote is simply referencing the dualistic nature of the Void / Light dichotomy , that both these forces are defined by their opposition to each other . M ' uru , now a darkened naaru , is now a boss in Sunwell Plateau . It is not clear if he is now " evil " , or simply a darkened naaru whose weakened state has been exploited by Kil ' jaeden or Kael ' thas . After the raid gets him to 0 % , he transforms into a void god named Entropius . Though Blizzard has addressed the confusion . Q : What is the nature of the Void state of the Na ' aru ? For a being of the Light , turning into such a dark being seems like a heavy weakness . Sucking in souls and causing destruction simply because of a loss in strength greatly diminishes their saintly image . Though , this might be a reason they don ' t act in combat very much , as turning on your army due to fatigue wouldn ' t be good for morale . A : " Because three cases of this " cycle " have been demonstrated in Nagrand , Auchindoun , and Sunwell Plateau ( K ' ure , D ' ore , and M ' uru , respectively ) , players may have received the wrong impression with regard to the magnitude and rarity of these events : it is EXCEEDINGLY rare for a naaru to fall into a void state , and even rarer for a fallen naaru to be brought back into the Light . A naaru ' s fall into the void represents a catastrophic loss for the naaru and for the forces of the Light , and it is the saddest , most heart - wrenching event for the naaru to witness . Conversely , a naaru being reborn into the Light brings renewed hope and sense of purpose to every naaru ; if energy beings could weep tears of joy , this would do it . " In relation to Ashbringer . Speculation exists that Ashbringer was crafted from part of a naaru , or is at least somehow related to the naaru . Factions . Various naaru - related factions exists in - game , some of which you can earn reputation with . Current factions : Prior to Patch 2 . 4 , there was also an abducted naaru named M ' uru within Silvermoon who was held captive by the channeling of Blood Elf sorcerers . This naaru was the source behind the Blood Knights ( Blood Elf paladins ) who drained the powers of the Holy Light from him . " At Kael ' thas Sunstrider ' s signal the elves stormed the dimensional fortress , quickly defeating its automated defenses and claiming its satellite structures . The only real threat the elves discovered was a lone naaru who had stayed behind to maintain the keep ' s defenses . With some difficulty , Kael ' thas subdued the energy being and sent it to Quel ' Thalas so that the magic - addicted blood elves could feed upon it . Back in the capital city of Silvermoon , Magister Astalor Bloodsworn was not content with this idea . After long months of study and experimentation , he and his fellow wizards learned how to manipulate and corrupt the naaru ' s luminous energies . In the end , the wizards devised a process by which the powers of the Light could be transferred to recipients who had not earned such abilities . Instead of feeding upon the naaru ' s magic , the blood elves would wield the naaru ' s Light - given powers themselves . " After patch 2 . 4 , Kael ' thas sent his Felblood minions to Silvermoon , and M ' uru was taken .
