Nyarlathotep, known to many by his epithet The Crawling Chaos, is an Outer God and the spawn of Azathoth.
Nyarlathotep differs from the other deities in the Mythos in a number of ways. Most of the Outer Gods are exiled to the stars, like Yog-Sothoth and Azathoth, and most of the Great Old Ones are sleeping and dreaming like Cthulhu; Nyarlathotep, however, is active and frequently walks the Earth in the guise of a human being, usually a tall, slim, joyous man. He has Òa thousandÓ other forms and manifestations, most reputed to be quite horrific and sanity-blasting.
