Nyarlahotep is the giver of great and terrible secrets. He is the Black Man of witches, the oone who reveals to them the workings of their spells, the proxy of the devil. He is the scientist who offers up a great discovery which should not be true, and yet stands revealed for the terrible fact that it does exist. He brings gifts of ancient wonder to the antiquarian and the historian, and watches asthe gifts consume those who have recieved them and slaying those with the temerity to try and prevent him from reclaiming his gifts.
Those who speak with him say much of his grace, decorum, and education even as they remark on the feverish intensity of his gaze. He comes in dreams as a beast whose howls draw the dreamer far astray. He comes in darkness as a thing of air with buurning eyes lobed three times, which sees the light as shadow and all in shadow revealed as by the sun. He speaks softly, and is known to many, but friend to none.
When the end is come, he will walk the world, and all will fall in his footsteps, driven mad by the mind and soul of the Other Gods, the Outer Gods.
