The sound comes from the soundtrack to Warhammer 40,000: Mechanicus, the 2018 tactics game focused on the Adeptus Mechanicus exploring a Necron tomb world. Composer Guillaume David blended chant, organ and industrial electronics to give the machine cult a distinct audio identity, and clips from the score spread through YouTube edits, lore channels and meme pages. Its mix of religious ritual and heavy machinery made it reusable far beyond gameplay, becoming a shorthand for tech priests, forge worlds and ominous Imperial technology in fan content.
