The Men Return
A Journey Through Ruins Older Than Memory

The Men Return by Jack Vance - Alpha caught a handful of air, a globe of blue liquid, a rock, kneaded them together....The Relict came furtively down the crag, a shambling gaunt creature with tortured eyes. He moved in a series of quick dashes, using panels of dark air for concealment, running behind each passing shadow, at times crawling on all fours, head low to the ground. Arriving at the final low outcrop of rock, he halted and peered across the plain.Far away rose low hills, blurring into the sky, which was mottled and sallow like poor milk-glass. The intervening plain spread like rotten velvet, black-green and wrinkled, streaked with ocher and rust. A fountain of liquid rock jetted high in the air, branched out into black coral. In the middle distance a family of gray objects evolved with a sense of purposeful destiny: spheres melted into pyramids, became domes, tufts of white spires, sky-piercing poles; then, as a final tour de force, tesseracts.The Relict cared nothing for this; he needed food and out on the plain were plants. They would suffice in lieu of anything better. They grew in the ground, or sometimes on a floating lump of water, or surrounding a core of hard black gas. There were dank black flaps of leaf, clumps of haggard thorn, pale green bulbs, stalks with leaves and contorted flowers. There were no recognizable species, and the Relict had no means of knowing if the leaves and tendrils he had eaten yesterday would poison him today.He tested the surface of the plain with his foot. The glassy surface (though it likewise seemed a construction of red and gray-green pyramids) accepted his weight, then suddenly sucked at his leg. In a frenzy he tore himself free, jumped back, squatted on the temporarily solid rock.
