Nyarlathotep is a fictional character created by H. P. Lovecraft. The character is a malign deity in the Cthulhu Mythos, a shared universe. First appearing in Lovecraft's 1920 prose poem "Nyarlathotep", he was later mentioned in other works by Lovecraft and by other writers, to the point of often being considered the main antagonist of the Cthulhu Mythos as a whole. He is presented as the messenger of Azathoth. He is later described by other authors as being part of the Other Gods, an alien pantheon.
