Integrity, reliability, efficiency, The eredar, an insidious race of devilish sorcerers, used their warlock magics to invade and enslave a number of worlds. The indigenous races of those worlds were mutated by the eredar's malevolent powers and turned into demons themselves. Though Sargeras' nearly limitless powers were more than enough to defeat the vile eredar, he was greatly troubled by the creatures' corruption and all-consuming evil. Incapable of fathoming such depravity, the great Titan began to slip into a brooding depression. Despite his growing unease, Sargeras rid the universe of the warlocks by trapping them within a corner of the Twisting Nether.
