Yogg-Saron is an Old God and the final boss of Ulduar in World of Warcraft, introduced with the Wrath of the Lich King raid in 2009. The fight is built around a sanity mechanic where looking at him and his illusions drives players mad, which is why lines like this became iconic among raiders. Clips of his distorted voice spread through raid videos, forums and soundboards, and the quote survived outside the game as a shorthand for corruption, obsession and a mind breaking under pressure.
