Fel magic The highly destructive fel magic is the magic of disorder . It is stated to be a brutal and extremely addictive energy fueled by drawing life from living beings . However , energy cannot be broken down or created and life energies are not some created resources to serve as fuel for energy . Fel energy is not some void that is devoid of energy and needs to absorb energy in order to function , move , or operate . If anything , fel magic is a spiritual magic that life force ( or Spirit ) is transformed into with the Life Tap ability . Spirit is a life - giving force that binds all things in existence as one , sacrificing its life . Sacrificial magic was considered the greatest violation of life and the titans ( living worlds ) had hounds , instantly attuned to punish those who delved into such sorcery , police the use of arcane magic - the magic of order . Together , the forces of disorder and order govern the cosmic systems of the physical universe . As the force of disorder , the highly destructive fel magic would ( or does ) affect systems . Indeed , concentrated fel energy can ( or does ) cause a system to go haywire . An Intro To Fel magic . From the moment the cosmos came to be , dark spirits within the Void sought to twist reality into a realm of eternal torment . These entities were known as the void lords and they pooled their power , hurling dark creatures throughout the physical universe . In time , these wicked beings would come to be known as Old Gods . These physical manifestations of the Void that exist only to transform the worlds they infest into places of despair and death . Deep within the fiery core of worlds that some Old Gods can infest , spirits known as world - souls were formed . These spirits are the spirits of the titans , godlike beings composed of the primordial matter from which the universe was born . They are essentially worlds and in an isolated corner of the Great Dark , a miraculous world was taking shape . Deep within this world ' s core , the spirit of a titan stirred to life and one day , it would be known as Azeroth . Eventually , a group of Old Gods plummeted down from the Great Dark and slammed into Azeroth ' s surface , embedding themselves in different locations across the world . As creations of the void lords , these Old Gods sought to corrupt Azeroth ' s world - soul . Now , some claim a dream born from Azeroth ' s slumbering world - soul is the Emerald Dream . In truth , the Emerald Dream was forged by incredible beings known as the keepers to act as a map for the evolutionary path of Azeroth ' s flora and fauna . Unfortunately to some , the evolutionary path of worlds can succumb to disorder . An Emerald Nightmare and Demons . One of the Old Gods , Yogg - Saron , used trees as a doorway into the Dream — a doorway through which the other Old Gods could grasp the ethereal domain as well . Small seeds of corruption were planted throughout the realm and , in time , these seeds polluted the dreamways . This marked the beginning of what would become known as the Emerald Nightmare . One place where the Nightmare held firmly is known as the Rift of Aln , which is believed bled into the Great Dark Beyond and the Twisting Nether , an astral dimension that the most unstable energies coalesced into . The creatures that had emerged from this turbulent realm were known as demons . Demons had been formed as a result of the Light and Void energies that had bled together at the borders of the Twisting Nether . With time , these bloodthirsty demons clawed their way into the physical universe , terrorizing mortal civilizations and bringing ruin to world after world . The titans feared that the demons would disturb the quest to find find and awaken other world - souls . Eventually , two titans went to war with the troublesome demons . Their names were Sargeras and Aggramar . While hunting demons by himself , Sargeras discovered the void lords ' plans to corrupt a slumbering world - soul . Sargeras knew that stopping them was impossible and he came to a troubling conclusion . Existence itself was flawed . The only way to spare the universe from the void lords was by burning away all creation and he would cleanse the universe in fire to thwart the void lords ' plans . And he would not stop this quest — this Burning Crusade — until every star had gone dark and he stood over a universe of embers . Despite Sargeras ' vast power though , he could not prosecute his Burning Crusade alone . He needed loyal servants , ones that would embrace their role as agents of destruction . He needed the very things he had sworn to destroy . He needed demons . The Burning Crusaders . Sargeras rallied the wicked creatures to his side , and he indulged in the terrible might of fel magic . The destructive energy enveloped his soul and scarred his noble form forever , but it also granted Sargeras power beyond anything he had ever known . The corrupted titan gave some of this newfound power to his demonic acolytes , uniting them as one in the emerald fires of fel magic . He named his growing army the Burning Legion , and he unleashed it upon the unsuspecting universe . Sargeras ' s former apprentice , Aggramar , hunted down this vast demonic army only to find that it was led by his beloved mentor . Aggramar demanded an explanation from the titan but received none . Sargeras would not abandon his Burning Crusade to extinguish all life in the cosmos . Not for Aggramar . Not for anyone . The mentor and his protege came to blows but Aggramar was no match for Sargeras ' s fel power and retreated from the battle , gathering the rest of the Pantheon to stop their fallen brother . Despite their earlier confrontation with Sargeras , Aggramar clung to the stubborn belief that he could bring his friend back to the side of good . He tried to reason with Sargeras one last time and tried to awaken whatever nobility still remained in his mentor ' s soul . In response , Sargeras annihilated Aggramar . The stunned members of the Pantheon made war on Sargeras but , in the end , Sargeras prevailed . He engulfed his kin a storm of fel fire and shattered their physical forms . God of Fel and Flame . Sargeras , dark god of chaotic magic , is the God of Fel and Flame . Once a noble warrior for order and peace , Sargeras came to believe there was a fundamental flaw in the universe , a flaw that made his primary purpose an impossible goal . He decided the other titan s were deeply misguided in trying to establish order throughout creation . Under the circumstances , the struggle was futile . The universe had to be destroyed utterly and remade without the underlying defect . Only then could true order be achieved . Thus , Sargeras conceived of a sweeping campaign to bring about the end of all things : the Burning Crusade . To carry out his plan , he created the Legion , whose ranks he bolstered by creating demons : immortal creatures whose hunger , power , and malice made them perfect killing machines . Professions of the cosmos . Demon Hunters . Demon hunter s , disciples of Illidan Stormrage , uphold a dark legacy , one that frightens allies and enemies alike . The Illidari embrace fel and chaotic magics — energies that have long threatened the world of Azeroth — believing them necessary to challenge the Burning Legion . Wielding the powers of demons they ' ve slain , they develop demonic features that incite revulsion and dread in fellow elves . Mages . Of the arcane , mages are diviners of secrets , balancing the ebb and flow of incredible mystic energies . Unparalleled skill is required to manipulate the volatile forces of the universe . These practitioners push their magical knowledge to its very limits — often to the brink of their own exhaustion , and at great risk to the world around them . Those who master this craft are capable of releasing a barrage of unrelenting power upon their enemies , drawing upon replenishing energies to maintain their assault for as long as the battle demands . It is stated that it is unimaginable that any mage would study fel magic , but it seems as if mages can — and / or do — study fel magic . Shaman . Shaman can be defined as fel , spiritual guides and practitioners , not of the divine , but of the very elements . Unlike some other mystics , shaman commune with forces that are not strictly benevolent . The elements are chaotic , and left to their own devices , they rage against one another in unending primal fury . It is the call of the shaman to bring balance to this chaos . Warlocks . Warlocks are magical practitioners of who seek to understand darker , fel - based magics , including destructive spells . According to Justin Parker , warlocks aren ' t necromancers even though they have necromantic abilities . It seems Justin Parker doesn ' t understand that warlocks can ' t have the abilities of necromancers without being necromancers . Perhaps a warlock is a necrolyte , which might not be a necromancer even though necrolytes were referred to as necromancers ? ( necrolyte is definitely spelled differently from necromancer ) . Necrolytes are binders of souls who command the black powers that hold control over the earth , which can be defined as the world . The living worlds are what the titans awoke as and they were uniquely susceptible ( and connected ) to fel magic . Presumably , this connection fel magic had with worlds allowed its users to manipulate a world and the spirits of the living and the dead residing within it . And through ceremonies , necrolytes learn to warp the essence of shadow to use for their advantage . Affliction warlocks are the masters of shadow magic , indulging in fel energies that wither away their life force over time . Warlocks can be considered the masters of shadow - touched powers , but unlike shadow priests — deadliest when pushed to the brink of insanity — the warlocks delight in using fel forces to cause intense pain and suffering in others . They revel in corrupting minds and agonizing souls , leaving enemies in a state of torment that would see them undone in due time . Even the most battle - hardened warriors can be deceived , landing blow after blow against the warlock , only to succumb to their suffering as their very vitality is siphoned away by the dark spellcaster . The denizens of the cosmos . Dark Naaru . The dark naaru are creatures of living holy energy and , presumably , shadow energy . 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 . Because dark naaru have both Light and Void energies , it could be possible that the Light and Void energies of a dark naaru can become unstable and coalesce into nether or bleed together at the borders of nether , forming demons and their fel energies . Demons . Willing or otherwise , all creatures who use the power of fel magic slowly take on the appearance of demons . Demons are evil immortals who feed upon life and magic . In order to become a demon , a creature must be infused with fel energy , the dark and corrupting essence wielded by the Burning Legion itself . The fallen titan Sargeras created this vast demonic army to scour all creation . The Burning Legion moves from world to world , decimating everything in its path with devastating fel magic . Eredar . The eredar are one of the oldest known races in the universe . Sargeras infused the eredar with fel energies , twisting their forms to resemble hideous demons , and found quick use for his new fel - corrupted converts . The eredar settled in as commanders within the Burning Legion . Under the eredar ' s leadership , the ranks of the Burning Legion swelled with new demonic races , gathered from the Twisting Nether and the world of the Great Dark . The eredar who rejected Sargeras ' s offer became known as draenei . Some of them had been affected by fel energies . These draenei mutated into lesser forms , resulting in a series of subspecies . The Broken and the Lost Ones are two such genetic offshoots . Their warped bodies bear only a rough resemblance to the proud draenei they once were , and quite a few lost their grip on sanity . Furbolgs . Furbolgs are hulking , simple - minded bear - men who live within the savage corners of Ashenvale forest . Though they have no special love for war or murder , their tribes have become increasingly hostile of late . There is a camp of Deadwood furbolgs in a place called Felwood . The Deadwood tribe is evil , but it is the effects of the fel that pollutes their minds . Their hostility is not truly an innate quality , yet they cannot be helped . Orcs . Orcs are beings that are rugged by nature . Initially , they lived as shamanic clans on the lush world of Draenor . They abandoned their peaceful culture when Kil ’ jaeden , a demon lord of the Burning Legion , corrupted the orcs and used them in his vengeful plot against the draenei , who were exiles from Kil ’ jaeden ’ s homeworld . Kil ’ jaeden ’ s plan worked . The orcs drank the blood of Mannoroth — a prominent Burning Legion general — infusing them with power and enslaving them to the Legion . Exposure to fel energies turned their naturally brown skin into a sickly green . Under the demon ’ s influence , the orcs killed off most of the draenei population , but Kil ’ jaeden would not stop there . Fel orcs are members of the orcish race who have been completely consumed by madness and bloodlust . Engineered by the Burning Legion , fel orcs are created by the continual consumption of pit lord blood . This results in a blood haze , uncontrollable bloodlust , and physical changes as well — bright red skin , sharp spines , and reddened eyes signify a fel orc as much as its maddened lust for destruction . Satyrs . The satyr s have been able to they come in contact with , which includes the ancient s that made Felwood their home . By the use of the fel , the spirit of the ancient has been bound and tortured , never completely released . Sin ' dorei . Blood elves are high elves who had turned to absorbing demonic magic after the loss of their vaunted power source , the Sunwell , and subsequently become addicted to the fel energies . They took the ways of demons to fight demons — indeed , actually draining the magic from demons like leeches . Felblood elf , aka Fel elf : blood elves loyal to Kael ' thas Sunstrider who have been granted demonic power . Sludge beasts . An entropic ooze is a foul slime that began to crawl the earth where the tree Vordrassil touched the ground . Vordrassil was once known as Andrissal , a tree with roots that had touched the prison of Yogg - Saron . The Old God had infused the tree with its foul energies , and thus all living creatures in the area were slowly being driven to madness . Andrissal was vulnerable to corruption and there was no way to spare the World Tree or ease its suffering . The only recourse , it was decided , was to destroy Andrissal . Titans . Composed of the primordial matter from which the universe was born , the titans are godlike beings that were uniquely susceptible ( and therefore connected ) to fel magic . Void revenants . Void revenants , remnants of a species overtaken by Void , are a race of parasitic void - beings that tear holes through the planes of reality , consuming and absorbing the energies and beings within . They can be fed overwhelming fel energies . Wild Gods . The Wild Gods are primal manifestations of life and nature . A number of Wild Gods can succumb to the poisoned black blades and fel powers wielded by the demons . The speculation section . Are Constructs The Source Of Fel Magic ? According to Sean Copeland the nature of fel magic is created from destroying something else . If fel magic comes from destruction , it does not come from the living because destruction is a process . Despite that fact , Sean told someone to " think burn life to create kind of thing " . Are Demons The Source Of Fel Magic ? According to Sean Copeland , demons contain fel magic but aren ' t the source , stating that the nature of this magic is created from destroying something else . Can A Warlock Exist Without A Fel Demon ? Demonic power is a nether - touched power that exists in - and is ultimately derived from - the Twisting Nether because demons are from the Twisting Nether . Despite that fact , after he was asked if perhaps warlocks are harnessing their power from the Twisting Nether , Sean Copeland - Blizzard ' s very own Lore Historian - stated , “ No , that ’ d be magi , IIRC . They gain power by the destruction of another source ( recall the undead warlock in original cinematic ) " Additionally , he claims that demons contain fel magic but aren ' t the source , stating that the nature of this magic is created from destroying something else . So not only is he denying that demons are the source of the demonic fel magic , he is denying that warlocks harness their power from the place demons and demonic powers are from . Ultimately , this person is claiming that a demonologist can exist without a demon and why is that ? Could it be because warlocks are essentially necromancers ( magi who have dabbled in dark magic ) if their power is from the Twisting Nether ? Is Fel From A realm of Chaos ? " While nearly all of the Orcish Hordes believed that our dead elders watched and guided us from the depths of some lost realm of chaos , I believed this notion to be a product of ritual and not reality . Within the Twisting Nether I discovered that the spirits of the dead do linger on , floating on the astral winds between the worlds . " - the warlock Gul ' dan Fel is the primal force of chaos and the force of chaos would be from a place of chaos , which the Twisting Nether is . If fel is from the Twisting Nether , perhaps the study of fel magic is necromancy because the Twisting Nether , according to the Warcraft II manual , is the realm of the dead where the spirits of the dead linger . It ' s important to note that although the Twisting Nether is the realm of the dead according to the Warcraft II manual , Blizzard produced a book that established that the Shadowlands is the place where many believe mortal souls are drawn into during the point of death . By channeling the necromantic powers of the underworld , or the Twisting Nether , one can create a field of dark energy that drains life - force . Even though it drains life , fel is not the same as death according to Micky Neilson — veteran of Blizzard Entertainment . Is Fel Magic A Form Of Life Magic Or Necromantic magic ? According to Sean Copeland , fel is entropic as in destroys life to fuel the caster ' s spells . Life — something described as eternal — is a construct if it can be destroyed because destruction , as stated before , is the process of destroying structures , breaking them down into the parts that they ’ re constructed of . Constructs are not living things and so how can animate beings be alive if the thing that animates them is not a living thing ? It is stated that only life could give life and if the thing that animates an animate being isn ’ t a living thing and therefore has no life , the study of magic involving an animate being can definitely be considered necromancy : One thing to consider is the fact that necromancy can be viewed as animancy ( or a form of it ) and that studying magic used to animate inanimate objects is studying magic one can use to animate the dead . After Micky Neilson was asked if life can be destroyed , he stated that it seems like just a change of energy and in most – if not all – fantasy settings , death ( or necromantic ) magic is considered to be a form of life magic ( it ’ s a form of magic and it ’ s the opposite of life magic ) . Presumably , this is because if life can be converted ( or transformed ) into another state , the state that life can be converted ( or transformed ) into would not be animate or living . And when regarding to World of Warcraft lore , warlocks ( according to how Dave Kosak describes it ) convert life into fel , draining the victim as a source of power . Fel is the primal force of chaos and can pool into a green goop when it ’ s in physical form . It is described as a substance and it can be animated ( is that substance alive when animated ? ) . Prior to being animated , fel is inanimate and so warlocks can , presumably , animate — or fuel — the fel by drawing life from living beings and be considered animancers or necromancers . Is Fel Magic A Manifestation Of The Void ? Disorder can be defined as a lack of order and it is manifested as fel magic . As such , one can consider fel magic to be a manifestation of a void , which can be defined as a lack . The void is chaotic since energies , naturally , want to spread out and become messy . Despite that fact , the writer Matt Burns stated that he thinks there are some exceptions to that rule when it comes to Warcraft powers . It seems that Matt Burns doesn ' t understand that his thoughts cannot change the fact that the void is devoid of order ( disorder ) , which is manifested as highly destructive fel magic - an energy that is fueled by drawing life from living beings . Is Fel Magic Actually Shadowflame ? " See how the shadowflame animates the bones ? They fight at my command ! " - Nefarian According to Dave Kosak , shadowflame is likely fel magic infused with shadow . However , it seems that shadowflame is actually a combination of shadow ( void ) and fire - a combination that doesn ' t seem possible to create . Void is described as dark and cold whereas fire is defined as light and heat . It seems that the void cannot be combined with light and heat because it would just suck the light and heat into non - existence . As such , fel magic — or fel flame — itself seems to be shadowfire : The fel flame spell emits a wave of shadowfire . Is Fel The Force Of Order ? Fel , as stated before , is the force of chaos , which is order unrecognized by a lesser mind according to the arcane user Iyyokuk the Lucid . It is stated that order is most commonly perceived as arcane magic in reality but that does not mean it ' s always perceived as arcane magic . This type of energy is innately volatile , and wielding it requires intense precision and concentration . Conversely , disorder is manifested as highly destructive fel magic . As the manifestation of disorder , fel magic cannot really exist without order because without order , there is no disorder . As such , perhaps fel magic is a form of arcane magic . If that ' s the case , the study of fel magic might be necromancy , which is described as a school of arcane magic by a book located at Dalaran . The RPG . The ultimate manifestation of the demonic arcane on Azeroth is fel ( aka " fel energy " or " fel magic " ) . This energy , which most commonly manifests itself as ghastly , green - yellow flame , is arcane magic at its most corrupt , for it employs the blood of demons . Unlike arcane magic , the use of fel magic corrupts the user ’ s body and soul . By contrast , the chief danger of arcane magic is that using it inevitably leads to the desire to wield greater power : power that only fel magic can provide . Since the Burning Legion returned to Azeroth , the world ' s heroes have encountered fel weapons and fel magic at an increasing frequency . As demon cults continue to fester and grow in Desolace , Ashenavle , and other remote corners , gruesome sacrifices are held to entice demons into giving their blood in trade . The cultists use their blood to enchant the weapons they hope will bring about their masters ' ultimate victory . Fel poison . Fel - poisoned creatures are another threat , appearing in places where the Burning Legion is strongest . Not even dragons are immune to the corruption of fel magic . When a creature with a natural poison attack is imbued with fel energy , its venom becomes more difficult to resist . Fel spells . Spells with the fel descriptor are very difficult to resist . Some arcanists can cast fel spells , perhaps after drinking demon blood . Casting a fel spell is described by many spellcasters as a euphoric experience . If arcane magic is an addiction , fel magic is the embodiment of the drug in its purest form . Demons sometimes tempt spellcasters by offering small amounts of their blood in exchange for services . If the recipient drinks the demon ' s blood within 24 hours of the offering , the next arcane spell they cast will be a fel spell . Fel blood is highly addictive as well as corrupting . Anyone who drinks it has a chance of becoming dependent on fel blood , and unless the person continues to drink it daily , they will suffer withdrawal symptoms . They have a chance of breaking the addiction seven days after first drinking the fel blood . Fel weapons . " The Burning Legion has no need for ammunition like cannonballs . The demons utilize far more potent weaponry . " - Dralor When the demons brought death and damnation to Azeroth , they also carried their own brand of magic to the world . Their blood had magical properties ; it addicted arcane magic users and could be used to create evil weapons . When a weapon is forged in demon blood , it becomes a fel weapon . It glows with a foul , yellow - green fire and deals extra damage to good - aligned opponents .
