Ghadamon, the Seed of Azathoth

Little is known about this Great Old One. The title itself betray its origin, a spawn of the Demon Sultan itself, the blue and grey shapeless horror with malformed and misshapen head, with body full of holes, its form oozing some viscous slime. It was called an End of Mankind, but its ploy and purpose is shrouded in a thick veil of mystery. And those who lay their gaze at its form goes surely mad, and so any description we have are a jumbled mess of destroyed sanities.
