Voidwalker Enigmatic and emanating pure demonic fury , a voidwalker is sometimes the last thing a person sees before crossing over to death . Background . Before life began , before even the cosmos took shape , there was Light . . . and there was Void . However , the Light , unfettered by the confines of time and space , swelled across all existence in the form of a boundless prismatic sea . Great torrents of living energy flitted through its mirrored depths , their movements conjuring a symphony of joy and hope . The Light ' s ocean was dynamic and ever shifting . Yet as it grew , some of its energies faded and dimmed , leaving behind pockets of seemingly cold nothingness . From the absence of Light in these spaces , a new power coalesced and came to be . A dark and vampiric force driven to devour all energy , to twist creation inward to feed upon itself , this power was the Void . The Void quickly grew and spread its influence , moving against the Light ' s flowing waves . The mounting tension between these two seemingly opposing yet inseparable energies eventually ignited a series of catastrophic explosions , rupturing the fabric of creation and birthing a new realm into existence . In that moment , the physical universe was born . Outland voidwalkers . The rogue voidwalkers seen in places like the Warp Fields notably wear what appear to be pauldrons , and sometimes breast plates , as opposed to bracers . The reason for this , and any difference it may make on their abilities , is unknown . Perhaps the voidwalkers on Azeroth are " shackled " from their original plane , like elementals . It will explain the lack of bracers on the Outland - voidwalkers as Outland technically is in the Twisting Nether Professions of the Cosmos . Warlocks . Warlocks are the most volatile and insatiable of spellcasters . Though they often pledge themselves to the service of noble causes and are not innately evil , their desire to understand darker magics and exercise unwavering command over demonic forces breeds mistrust among even their closest allies . Warlocks peer into the Void without hesitation , leveraging the chaos they glimpse within to devastating ends in battle — their greatest abilities are fueled by the souls they ’ ve harvested from their victims . They can also summon and command voidwalkers to do their bidding . The RPG . The voidwalker is often a warlock ’ s choice fel companion for its ability to intercept a single foe and keep him or her occupied . Many warlocks also prefer to do without the mischievousness of an imp or the jealousy of a succubus , preferring instead the unwavering , silent loyalty of a voidwalker . These hulking blue creatures look vaguely humanoid . It seems to appear from within a black cloud as dark as the void . A voidwalker ’ s sole purpose is to unconditionally serve a master . A voidwalker does not hesitate to follow even the most suicidal commands its master gives . A voidwalker ’ s master often sends it to block a threat , leaving the master free to cast spells or use other abilities without interference . A voidwalker takes its orders literally ; when out of communication with its master , it continues to obey its last command , even if that command is tactically unsound . Their touch is misery , and it can momentarily blind a creature ' s awareness to other threats . The touch of a voidwalker brings a victim ’ s most painful memories rushing to the surface ; for a brief moment , she can think of nothing but destroying the source of this mental anguish . Like elementals , voidwalkers , whether summoned to Azeroth or arriving of their own free will , wear a set of magic bracers . These bracers form automatically when the voidwalker leaves the Twisting Nether , tying the voidwalker to Azeroth and allowing it to exist outside of the Twisting Nether . A voidwalker that loses its bracers also loses much of its power and might inadvertently return to the Twisting Nether . A voidwalker can absorb the darkness surrounding it , thereby healing itself of wounds ; A voidwalker in total darkness can spend time concentrating drawing the darkness in and producing a faint indigo light around its body . A voidwalker may consume shadows in shadowy illumination but heals only half as much as it would in total darkness . If the voidwalker takes damage while using consume shadows , it may lose concentration and fail in the attempt . Voidwalkers can understand Eredun , but do not speak it .
