The Leader's Etiquette is a treatise on the finer points of leadership authored by Pi. While it makes no specifc mention of any individuals, Nut alleged that it was a veiled response to his falling out with Elite. Though they had been friends since their days in Pi Hole during the Second Era, Elite killed him under suspicion of sabotaging Sanctuary on the orders of the Dragonslayers. The two waged a war of words through the community forum and Pi simultaneously published The Leader's Etiquette.
