[Nyarlathotep]

from the Cthulhu Lexicon

Nyarlathotep. (Pronounced either ni-ar-lat-ho-tep or nyar-lat-ho-tep). The messenger of the Great Old Ones, also named, among other things, the Black Man. Nyarlathotep is considered an Outer God. The Haunter of the Dark is an avatar of Nyarlathotep. Nyarlathotep is the messenger of Azathoth and the one member of the Mythos who deals on a personal level with human beings in general. He is described, in his human form at least, as being of the old native blood of Egypt and looking like a Pharaoh. Wherever he visits, rest vanishes and the wails of nightmares untold echoes through the streets. Nyarlathotep is especially fond of technology and psychology.
