The Prophet of Calm was a Prophet who replaced the Prophet of Objection in leading the Age of Insanity. He was a completely insane meglomaniac who wanted to destroy the whole universe, rather like this guy. However, Calm went about it in an odd way. He would shout and scream at people until they died, he even tried this on a wall to make it fall over. He was eventually overthrown and put in a mental home, only to break out and go on a murderous rampage, killing fourteen thousand Brutes. No-one cared.
