And they went back unto their Cities; and lived there mayhaps an hundred thousand years; and grew wise and cunning in all matters; and their Wise People did make dealings and had experiment with those Forces which are Distasteful and Harmful unto Life; but they did this in Ignorance; for all that they had much wisdom; thinking only to Experiment, that they come to greater knowings. But they did open a way for those Forces; and much harm and Pity did come thereby. And then had all People to have Regret; yet too late. Now, presently, when an hundred thousand years had gone, or it may be a greater space; there came slowly the utter twilight of the world, as the sun to die the more; so that presently it gave but an utter gloomy light. And there grew upon many of the Peoples of the Cities of the Valley, a strangeness and a wildness; so that strange things were done, that had been shameful to all in the Light. And there were wanderings, and consortings with strange outward beings, and presently, many Cities were attacked by monsters that did come from the West; and there was a Pandemonium. Then was an Age of Sorrows and Fightings, and Hardenings of the Spirit and of the Heart, for all that were of good Fibre; and this did breed a Determined Generation; and there grew up into the World a Leader; and he took all the sound Millions; and did make a mighty Battle upon all Foulness and upon all that did harm and trouble them; and they drove their Enemies down the Valley, and up the Valley, and did utterly scatter and put them to flight. Then did that Man call all his Peoples together; and did make it plain how that the Darkness grew upon the World, and that the Foul and dreadful Powers abroad, were like to be more Horrid when a greater Gloom came. And he put to them that they Build a Mighty Refuge; and the Peoples did acclaim; and lo! there was built, presently, a Great House. But the Great House was not Proper; and that Man did take all the Peoples to Wander; and they came to the Bight; and there was built at last that Great and Mighty Pyramid. Now this is the sense and telling of that book; and but late had I read it; and talked somewhat of it with my dear friend, the Master Monstruwacan; but not overmuch; for I had taken so sudden a mind to GO, that all else had dropped from about me. Yet, to us it did seem clear that there was no life in all the invisible upper world; and that, surely, that Great Road whereon the Silent Ones did walk, must be that same Road which the hardy Peoples of that age did make. And it did seem wise to the Master Monstruwacan, and unto me, that if any should find the Lesser Redoubt, they must surely do so somewhere within the mighty Valley; but whether The Road that led into the West, where was the Place of the Ab-humans, should bring me to it, I had no knowing; nor whether it might lie on the Northward way. And I, maybe, to wander a thousand miles wrong; if, in truth, I were not into some dreadful trouble before.
