Nyarlathotep is the soul and messenger of the Outer Gods and, unlike the others, appears before humans directly. Called "the Crawling Chaos," it takes a thousand forms and topples civilizations from within.
Where the other gods are indifferent, Nyarlathotep actively mocks and deceives humanity. Baiting people with knowledge and illusion toward ruin, it is the most human and the most malicious presence in the Mythos.
