Down it he went recklessly, and was presently peering into a larger cavern than the one he had just left. There was no phosphorus here, but the light of the torches fell on a larger altar and a more obscene and repulsive god squatting toad-like upon it. Before this repugnant deity Gorulga and his ten acolytes knelt and beat their heads upon the ground, while chanting monotonously. Conan realized why their progress had been so slow. Evidently approaching the secret crypt of the Teeth was a complicated and elaborate ritual. He was fidgeting in nervous impatience before the chanting and bowing were over, but presently they rose and passed into the tunnel which opened behind the idol. Their torches bobbed away into the nighted vault, and he followed swiftly. Not much danger of being discovered. He glided along the shadows like a creature of the night, and the black priests were completely engrossed in their ceremonial mummery. Apparently they had not even noticed the absence of Gwarunga. Emerging into a cavern of huge proportions, about whose upward curving walls gallery-like ledges marched in tiers, they began their worship anew before an altar which was larger, and a god which was more disgusting, than any encountered thus far. Conan crouched in the black mouth of the tunnel, staring at the walls reflecting the lurid glow of the torches. He saw a carven stone stair winding up from tier to tier of the galleries; the roof was lost in darkness. He started violently and the chanting broke off as the kneeling blacks flung up their heads. An inhuman voice boomed out high above them. They froze on their knees, their faces turned upward with a ghastly blue hue in the sudden glare of a weird light that burst blindingly up near the lofty roof and then burned with a throbbing glow. That glare lighted a gallery and a cry went up from the high priest, echoed shudderingly by his acolytes. In the flash there had been briefly disclosed to them a slim white figure standing upright in a sheen of silk and a glint of jewel-crusted gold. Then the blaze smoldered to a throbbing, pulsing luminosity in which nothing was distinct, and that slim shape was but a shimmering blue of ivory. 'Yelaya!' screamed Gorulga, his brown features ashen. 'Why have you followed us? What is your pleasure?' That weird unhuman voice rolled down from the roof, re-echoing under that arching vault that magnified and altered it beyond recognition. 'Woe to the unbelievers! Woe to the false children of Keshia! Doom to them which deny their deity!' A cry of horror went up from the priests. Gorulga looked like a shocked vulture in the glare of the torches. 'I do not understand!' he stammered. 'We are faithful. In the chamber of the oracle you told us--'
