Argus was ruled by a triumvirate of the greatest and most powerful eredar mages: Archimonde, Kil'jaeden, and Velen. It is possible that they ruled from Mac'Aree — the most sacred of the cities on Argus according to Jessera of Mac'Aree.
Eventually, Argus attracted the attention of Sargeras. He offered the eredar a deal: in exchange for their loyalty, he would give them power undreamed of by all races. Kil'jaeden and Archimonde were quick to accept the offer, but Velen had a vision of the future: the eredar would be transformed into demons, under the rule of Sargeras. His advice to Kil'jaeden and Archimonde went unheeded, and he desperately sought a solution to this dilemma. Eventually, Velen was contacted by the naaru, and he fled with his followers, renaming his people the draenei, or "exiled ones". , obtained now via archaeology, was taken by one of the draenei from Argus.
Kil'jaeden, Archimonde and the rest of the eredar became the feared, insidious sorcerers and tacticians of the Burning Legion.
Argus has since become the stronghold of the Burning Legion.
It seemed to have many high and cold mountains, like Kaarinos. It also has desert, as revealed in Rise of the Horde novel.
The capital city Mac'Aree was the most sacred and beautiful city on Argus. The walkways were lined with precious minerals and the rivers glittered even in complete darkness. The Eredar prior to their corruption by Sargeras, and the Draenei, before they lives in Draenor, have great love and respect for Mac'Aree. The Last Relic of Argus has the inscription "I long for Mac'Aree".
- The word "Argus" is also present in StarCraft: Brood War, another Blizzard strategy game. The Argus Talisman grants Dark Archons more energy, the Argus Jewel does the same for Dark Templar Corsairs and the Argus Stone exists on Aridas. None of these entities or groups are related to the world of Argus. It is not known what the name implies in relation to Blizzard's universes.
- Argus or Argos (Anc. Greek: Ἄργος) is the name of several mythological figures, as well as one of the major cities of Bronze Age Greece.
