The Crawling Chaos has never played the rules, which states that they mustn't directly interfere with humanity to turn the tide in their favor, so I while I don't doubt he had a claw in the process it wasn't strictly something he had thought about for an extended period of time. It more or less happened in his favor, and thus you were called upon by Lord Philemon to cease the Crawling Chaos's development."
