This is a World Of Warcraft (WoW) Background that has Kil'jaeden the Deceiver.
A little information about him:
Kil'jaeden (pronounced Kill-Jay-Den) is a powerful eredar demon lord and is the acting leader of the Burning Legion. Elected twenty-five thousand years ago as the chief lieutenant of Sargeras, he was ranked above the now-deceased demon lord, Archimonde. While Archimonde had led the Legion's armies, Kil'jaeden's agenda was to assimilate every race possible into the folds of the Burning Legion. Since the apparent banishment of Sargeras, he has assumed the role of supreme commander.
He is also the creator of the Lich King.
