The eredar were a race of supremely talented magic-wielders who arose on the planet Argus (Eventually, Argus attracted the attention of Sargeras.) countless millenia ago. There, they built a vast civilization of wondrous cities and a peaceful way of life. But 25,000 years ago, the tranquility of Argus was shattered.
History The great titan Sargeras (Sargeras the Destroyer, the Fallen Titan, is the creator and leader of the Burning Legion.), in order to create a great Legion, planned to bolster his ranks by creating demons.[1] He was attracted by the eredar's magical affinity, and contacted them, promising their three leaders, Archimonde (Archimonde the Defiler was the left hand of the fallen titan, Sargeras.), Kil'jaeden (Kalecgos BrutallusFelmystEredar TwinsM'uruKil'jaeden
Kil'jaeden the Deceiver is a powerful eredar demon lord and is the acting leader of the Burning Legion.), and Velen (Prophet Velen is a level ?? quest giver located in the Vault of Lights in the draenei capital at the Exodar.), immortality and vast powers. Despite Velen's misgivings, Archimonde and Kil'jaeden agreed to join Sargeras' Burning Legion (The Burning Legion (aka demon hordeDotD 161) is a massive army of demons, infernals, and corrupted races who seek to destroy any trace of order in the Universe.). The eredar were the first sentient race to pledge their allegiance to Sargeras. Knowing that other sentient beings would inevitably join the Legion, the eredar declared that their primary language, Eredun (Eredun (aka Demonic) is the language of the demons of the Burning Legion.), would be the Legion's common language.[2]
With his fellow eredar already becoming corrupted by demonic power, Velen led a group of his people away from Argus with the help of the 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 paladins of Azeroth.), renaming themselves the draenei (The draenei (pronounced as DRAN-eye) are a faction of uncorrupted eredar who fled their home world of Argus.), or "Exiled Ones" in Eredun (Eredun (aka Demonic) is the language of the demons of the Burning Legion.). The eredar under Kil'jaeden were infuriated with what they perceived as a betrayal, and hunted Velen and the draenei across several worlds. The indigenous races of those worlds were oftentimes mutated by the eredar's malevolent warlock (Warlocks were once mages or, in case of the orcs, shamans, who, in pursuit of ever-greater sources of power, abandoned their studies of the Nature or Arcane and delved into darker Shadow-based magic.) powers and turned into demons (Hellish, twisted creatures found on the worlds conquered by the Burning Legion.) themselves.
Both factions continued to use the Eredun language, though specific dialects have evolved.
The draenei traveled through the cosmos and eventually discovered a world which they decided to settle down upon. They named this world Draenor, or Exiles' Refuge. At first there was peace with the native orcs (The green skinned orcs are one of the most prolific races of Azeroth.) living there, and they struck up trade and diplomacy with the shamanistic (The Shaman (for correct spelling and more on the word, see Shaman Spelling) is a healer - warrior - mage hybrid class, and as such, Shamans are considered one of the most versatile classes in the game.) race. But soon the draenei's existence there led the evil eredar to Draenor. The Eredar then began to corrupt the orcs, turning them into a warlike race and granting them access to warlock magics. The orcs subsequently hunted down the draenei, almost wiping out the entire race.
It is unclear what exactly became of the eredar home world, Argus. Some believe that the demons devoured their own world by using radical warlock magics, though information recently offered by the draenei suggest Sargeras was responsible for the planet's destruction. It is possible that the planet was not actually destroyed, but simply stripped of life, in which case it would be a major stronghold of the Legion.
The eredar consumed all life around them and set out to find more places of mystical power. Eredar warlocks are now counted as some of the greatest sorcerers in the universe, and Archimonde and Kil'jaeden are almost as feared as Sargeras.
It is suggested that the eredar were the first race to discover and master magic, barring the Titans (The Titans are a race of extremely powerful, godlike beings who travel across the cosmos bringing order to worlds.). They are referred to as "one of the oldest known races in the universe,"[3] so long-ago mastery of magic is nowhere near implausible.
Other LegendsThis may include editing and reducing sections to ensure they are clear and concise paraphrases, and wikifying.According to the existing lore it is said that most if not all demons (including the eredar) were mortal once, but have been transformed into demons by corruption caused by Fel Energy (The ultimate manifestation of the demonic arcane on Azeroth is fel energy (aka fel, fel magic).). This change includes a powerful command of arcane energy.MoM 112MG 188 This possibility was presented by Sargeras himself, which might point to the ultimate truth. It is said that Sargeras believed that the demons originally were not corrupt, and that it was the Titan's ordering of the universe that was ultimately responsible for the demons corruption.S&L 122 In this scenario, it would imply that the titans considered the various natural races that pre-existed on worlds they visited to be demons (either because they had societies based on the use of arcane magic, or tried to defend themselves from the the invading titans). The titans including Sargeras battled them, and locked them up and took over their worlds. Sargeras later came back and freed many of them, bent on using them to destroy the Titan's work. However, another legend states that Sargeras never actually battled any demons before going mad, and was the one that actually created them from mortals in the first place.
Some of the other legends for Eredar include;From Warcraft III manual;
Lore (Lore generally describes the extensive backstory created around the Warcraft universe and further developed in novels and other media.) from [http://www.worldofwarcraft.com/info/story/chapter1.html#2 WorldofWarcraft.com;From Chapter I: Mythos;
From Manual of Monsters (The Manual of Monsters is a source book for the Warcraft RPG and was published in 2003.);
Another possibility is that the eredar were evil to begin with, and that it was only after Velen's vision that a faction within the eredar started to seek salvation from the naaru.
Eredar racial tree speculation The exact racial history of the eredar is not clear. Some believe that both Lost Ones (The Draenei Lost Ones are highly mutated and devolved draenei.) and Broken (The Broken draenei (Krokul in Draenei) are the racial offshoots of the eredar draenei who lived in Outland.) diverged directly from the draenei along separate divergent paths.
