By now the set was warm. He felt the squares of space around him, sensed himself at the middle ofan immense grid, a cubic grid, full of nothing. Out in that nothingness, he could sense the hollow achinghorror of space itself and could feel the terrible anxiety which his mind encountered whenever it met the faintest trace of inert dust.As he relaxed, the comforting solidity of the Sun, the clockwork of the familiar planets and the moonrang in on him. Our own solar system was as charming and as simple as an ancient cuckoo clock filled with familiar ticking and with reassuring noises. The odd little moons of Mars swung around their planet like frantic mice, yet their regularity was itself an assurance that all was well. Far above the plane of the ecliptic, he could feel half a ton of dust more or less drifting outside the lanes of human travel.Here there was nothing to fight, nothing to challenge the mind, to tear the living soul out of a body with its roots dripping in effluvium as tangible as blood.
