When the two upon the lidis had come quite close to us we saw that one was a man and the other a woman. The former had held up his two hands, palms toward us, in sign of peace, and I had answered him in kind, when he suddenly gave a cry of astonishment and pleasure, and slipping from his enormous mount ran forward toward Dian, throwing his arms about her. In an instant I was white with jealousy, but only for an instant; since Dian quickly drew the man toward me, telling him that I was David, her mate. "And this is my brother, Dacor the Strong One, David," she said to me. It appeared that the woman was Dacor's mate. He had found none to his liking among the Sari, nor farther on until he had come to the land of the Thoria, and there he had found and fought for this very lovely Thorian maiden whom he was bringing back to his own people. When they had heard our story and our plans they decided to accompany us to Sari, that Dacor and Ghak might come to an agreement relative to an alliance, as Dacor was quite as enthusiastic about the proposed annihilation of the Mahars and Sagoths as either Dian or I. After a journey which was, for Pellucidar, quite uneventful, we came to the first of the Sarian villages which consists of between one and two hundred artificial caves cut into the face of a great cliff. Here to our immense delight, we found both Perry and Ghak. The old man was quite overcome at sight of me for he had long since given me up as dead. When I introduced Dian as my wife, he didn't quite know what to say, but he afterward remarked that with the pick of two worlds I could not have done better. Ghak and Dacor reached a very amicable arrangement, and it was at a council of the head men of the various tribes of the Sari that the eventual form of government was tentatively agreed upon. Roughly, the various kingdoms were to remain virtually independent, but there was to be one great overlord, or emperor. It was decided that I should be the first of the dynasty of the emperors of Pellucidar. We set about teaching the women how to make bows and arrows, and poison pouches. The young men hunted the vipers which provided the virus, and it was they who mined the iron ore, and fashioned the swords under Perry's direction. Rapidly the fever spread from one tribe to another until representatives from nations so far distant that the Sarians had never even heard of them came in to take the oath of allegiance which we required, and to learn the art of making the new weapons and using them. We sent our young men out as instructors to every nation of the federation, and the movement had reached colossal proportions before the Mahars discovered it. The first intimation they had was when three of their great slave caravans were annihilated in rapid succession. They could not comprehend that the lower orders had suddenly developed a power which rendered them really formidable.
