The chief reason was physical. The Plains, still called Forbidden, ringed the mountain like a protective wall, and it was an indisputable fact whether you liked it or not that people who went out onto them didn't come back. Hunger, thirst, wild beasts, or devils—they didn't come back. That discouraged a lot of traveling. Besides, the only reason for attempting to reach Ben Beatha was the legend of the Stone of Destiny, and people had long ago lost faith in that. Nobody had seen it. Nobody had seen Bas the Immortal who was its god and guardian, nor the androids that were his servants, nor the Kalds that were slaves to both of them. Long, long ago people were supposed to have seen them. In the beginning, according to the legends, Bas the Immortal had lived in a distant place—a green world where there was only one huge sunball that rose and set regularly, where the sky was sometimes blue and sometimes black and silver, and where the horizon curved down. The manifest idiocy of all that still tickled people so they liked to hear songs about it. Somewhere on that green world, somehow, Bas had acquired the flaming stone that gave him the power of life and death and destiny. There were a lot of conflicting and confused stories about trouble between Bas and the inhabitants of the funny world with the sky that changed like a woman's fancy. Eventually he was supposed to have gathered up a lot of these inhabitants through the power of the stone and transported them somehow across a great distance to the world where they now lived. Ciaran had found that children loved these yarns particularly. Their imaginations were still elastic enough not to see the ridiculous side. He always gave the Distance Cycle a lot of schmaltz. So after Bas the Immortal and his Stone of Destiny had got all these people settled in a new world, Bas created his androids, Khafre and Steud, and brought the Kalds from somewhere out in that vague Distance; another world, perhaps. And there were wars and revolts and raiding parties, and bitter struggles between Bas and the androids and the humans for power, with Bas always winning because of the Stone. There was a bottomless well of material there for ballads. Ciaran used it frequently. But the one legend that had always maintained its original shape under the battering of generations was the one about Ben Beatha, the Mountain of Life, being the dwelling place of Bas the Immortal and his androids and the Kalds. And somewhere under Ben Beatha was the Stone, whose possession could give a man life
