The line comes from Illidan Stormrage, a central character in Blizzard's Warcraft universe, and was popularised by the cinematic trailer for World of Warcraft: The Burning Crusade in 2007. Spoken as a warning to heroes approaching the Black Temple, it quickly spread beyond the game as a meme for anyone facing something far beyond their skill level. Its dramatic delivery made it easy to reuse in gaming videos, streams and edits, and it remains recognised because the phrase works both as a genuine threat and as a joke.
