The slant-eyed merchant had now prodded Carter into a great domed space whose walls were carved in shocking bas-reliefs, and whose centre held a gaping circular pit surrounded by six malignly stained stone altars in a ring. There was no light in this vast evil-smelling crypt, and the small lamp of the sinister merchant shone so feebly that one could grasp details only little by little. At the farther end was a high stone dais reached by five steps; and there on a golden throne sat a lumpish figure robed in yellow silk figured with red and having a yellow silken mask over its face. To this being the slant-eyed man made certain signs with his hands, and the lurker in the dark replied by raising a disgustingly carven flute of ivory in silk-covered paws and blowing certain loathsome sounds from beneath its flowing yellow mask. This colloquy went on for some time, and to Carter there was something sickeningly familiar in the sound of that flute and the stench of the malodorous place. It made him think of a frightful red-litten city and of the revolting procession that once filed through it; of that, and of an awful climb through lunar countryside beyond, before the rescuing rush of earth's friendly cats. He knew that the creature on the dais was without doubt the High-Priest Not To Be Described, of which legend whispers such fiendish and abnormal possibilities, but he feared to think just what that abhorred High-Priest might be.
