The eastern stars were fading at the first hint of coming dawn when the two scrambled up a precipitous bank that formed the upper end of the ravine, and came out upon comparatively level ground. As they advanced the sky lightened, and presently the woman halted at the edge of a declivity, and as the day broke Tarzan saw below him a wooded basin in the heart of the mountain, and, showing through the trees at what appeared to be some two or three miles distant, the outlines of a building that glistened and sparkled and scintillated in the light of the new sun. Then he turned and looked at his companion, and surprise and consternation were writ upon his face, for standing before him was La, the High Priestess of Opar.

“You?” he exclaimed. “Now indeed will Cadj have the excuse that Dooth said he sought to put you out of the way.”

“He will never have the opportunity to put me out of the way,” replied La, “for I shall never return to Opar.”

“Never return to Opar!” he exclaimed, “then where are you going? Where can you go?”

“I am going with you,” she replied. “I do not ask that you love me. I only ask that you take me away from Opar and from the enemies who would slay me. There was no other way. Manu, the monkey, overheard them plotting, and he came to me and told me all that they would do. Whether I saved you or sacrificed you, it had all been the same with me. They were determined to do away with me, that Oah might be High Priestess and Cadj king of Opar. But I should not have sacrificed you, Tarzan, under any circumstances, and this, then, seemed the only way in which we might both be saved. We could not go to the north or the west across the plain of Opar for there Cadj has placed warriors in ambush to waylay you, and though you be Tarzan and a mighty fighter, they would overwhelm you by their very numbers and slay you.”

“But where are you leading me?” asked Tarzan.

“I have chosen the lesser of two evils; in this direction lies an unknown country, filled for us Oparians with legends of grim monsters and strange people. Never has an Oparian ventured here and returned again to Opar. But if there lives in all the world a creature who could win through this unknown valley, it be you, Tarzan of the Apes.”

“But if you know nothing of this country, or its inhabitants,” demanded Tarzan, “how is it that you so well know the trail that leads to it?”

“We well know the trail to the summit, but that is as far as I have ever been before. The great apes and the lions use this trail when they come down into Opar. The lions, of course, cannot tell us where it leads, and the great apes will not, for usually we are at war with them. Along this trail they come down into Opar to steal our people, and upon this trail we await to capture them, for often we offer a great ape in sacrifice to the Flaming God, or rather that was our former custom, but for many years they have been too wary for us, the toll being upon the other side, though we do not know for what purpose they steal our people, unless it be that they eat them. They are a very powerful race, standing higher than Bolgani, the gorilla, and infinitely more cunning, for, as there is ape blood in our veins, so is there human blood in the veins of these great apes that dwell in the valley above Opar.”

“Why is it, La, that we must pass through this valley in order to escape from Opar? There must be some other way.”
