Like a slightly painful flash of light against the eyes. Yet in that time, a forty-thousand-ton ship lifting free above Earth disappeared somehow or other into two dimensions and appeared half a light-year or fifty light-years off. At one moment, he would be sitting in the Fighting Room, the pin-set ready and the familiar Solar System ticking around inside his head. For a second or a year (he could never tell how long it really was, subjectively), the funny little flash went through him and then he was loose in the Up-and-Out, the terrible open spaces between the stars, where the stars themselves felt like pimples on his telepathic mind and the planets were too far away to be sensed or read. Somewhere in this outer space, a gruesome death awaited, death and horror of a kind which Man had never encountered until he reached out for inter-stellar space itself. Apparently the light of the suns kept the Dragons away. ragons. That was what people called them. To ordinary people, there was nothing, nothing except the shiver of planoforming and the hammer blow of sudden death or the dark spastic note of lunacy descending into their minds. But to the telepaths, they were Dragons. In the fraction of a second between the telepaths' awareness of a hostile something out in the black, hollow nothingness of space and the impact of a ferocious, ruinous psychic blow against all living things within the ship, the telepaths had sensed entities something like the Dragons of ancient human lore, beasts more clever than beasts, demons more tangible than demons, hungry vortices of aliveness and hate compounded by unknown means out of the thin tenuous matter between the stars. It took a surviving ship to bring back the news—a ship in which, by sheer chance, a telepath had a light beam ready, turning it out at the innocent dust so that, within the panorama of his mind, the Dragon dissolved into nothing at all and the other passengers, themselves non-telepathic, went about their way not realizing that their own immediate deaths had been averted. From then on, it was easy—almost. lanoforming ships always carried telepaths. Telepaths had their sensitiveness enlarged to an immense range by the pin-sets, which were telepathic amplifiers adapted to the mammal mind. The pin-sets in turn were electronically geared into small dirigible light bombs. Light did it.
