The audio is taken from Lucifer's Hymn, a dark choir composition by Peter Gundry, and it circulates on soundboards under the shorter name Cult Follow. Gundry is known for dramatic, cinematic choral and orchestral pieces that lend themselves to trailers and fan edits, and this passage stands out for its solemn, ritual-like chant. Online creators adopted it as shorthand for secret societies, villain introductions and horror reveals, because the choir alone suggests ceremony without needing dialogue. That simple association keeps it in regular use across short-form edits and memes.
