The World of Warcraft: Burning Crusade Bestiary Section was updated with the Eredars:
The eredar are one of the oldest known races in the universe. They comprise the commanders and strategists of the Burning Legion. Exceptionally skilled in magic, their mastery of the arcane arts is renowned throughout the scattered worlds of the Great Dark Beyond. The likes of Archimonde and Kil’jaeden, feared and loathed for their unmatched cruelty and cunning, are among the more infamous members of the eredar race ? the vanguard of an unstoppable, demonic army bent on universal annihilation.
