The Great Unnameable One

From Nameless Cults , by Wilhelm Friedrich Von Juntz, translator unknown, edition released by Golden Goblin Press, 1909.

I wandered amongst the horrible stone villages on the icy desert plateau of Leng, which no timid folk visit and whose fires are seen at night from afar, and I spake to a merchant there. He was rumoured to have dealt with that high-priest not to be described, which wears a yellow silken mask over its face and dwells all alone in a prehistoric stone monastery.

- From "The Repairer of Reputations," by Robert W. Chambers

I showed him a list of thousands of names which Mr. Wilde had drawn up; every man whose name was there had received the Yellow Sign which no living human being dared disregard. The city, the state, the whole land, were ready to rise and tremble before the Pallid Mask. The time had come, the people should know the son of Hastur, and the whole world bow to the black stars which hang in the sky over Carcosa... I had a blank bit of paper in my pocket, on which was traced the Yellow Sign, and I handed it to him. He looked at it stupidly for a moment, and then with an uncertain glance at me, folded it with what seemed to me exaggerated care and placed it in his bosom.
