Does anyone know where the audio sample from the beginning of 'Chain of Prophecies' is from? 'As they would spin, they would tell stories, and among these stories, we find a chain of prophecies centered on this spindle ... and they said 'you know someday, just before purification day, we'll see objects or machines rolling across the ground on round things like this ... and that's the time to get ready for the great testing and trial and tribulation because it will soon be upon us.'
