At dusk they reached the jagged grey peaks that form the barrier of Inquanok, and hovered about these strange caves near the summits which Carter recalled as so frightful to the Shantaks. At the insistent meeping of the ghoulish leaders there issued forth from each lofty burrow a stream of horned black flyers with which the ghouls and night-gaunts of the party conferred at length by means of ugly gestures. It soon became clear that the best course would be that over the cold waste north of Inquanok, for Leng's northward reaches are full of unseen pitfalls that even the night-gaunts dislike; abysmal influences centering in certain white hemispherical buildings on curious knolls, which common folklore associates unpleasantly with the Other Gods and their crawling chaos Nyarlathotep.
