On the second night he camped in the shadow of a large black crag, tethering his yak to a stake driven in the ground. He observed the greater phosphorescence of the clouds at this northerly point, and more than once thought he saw dark shapes outlined against them. And on the third morning he came in sight of the first onyx quarry, and greeted the men who there laboured with picks and chisels. Before evening he had passed eleven quarries; the land being here given over altogether to onyx cliffs and boulders, with no vegetation at all, but only great rocky fragments scattered about a floor of black earth, with the grey impassable peaks always rising gaunt and sinister on his right. The third night he spent in a camp of quarry men whose flickering fires cast weird reflections on the polished cliffs to the west. And they sang many songs and told many tales, shewing such strange knowledge of the olden days and the habits of gods that Carter could see they held many latent memories of their sires the Great Ones. They asked him whither he went, and cautioned him not to go too far to the north; but he replied that he was seeking new cliffs of onyx, and would take no more risks than were common among prospectors. In the morning he bade them adieu and rode on into the darkening north, where they had warned him he would find the feared and unvisited quarry whence hands older than men's hands had wrenched prodigious blocks. But he did not like it when, turning back to wave a last farewell, he thought he saw approaching the camp that squat and evasive old merchant with slanting eyes, whose conjectured traffick with Leng was the gossip of distant Dylath-Leen.
