Now the giant central world beneath was no longer visible, as we raced upward and outward from it at terrific speed, and ahead loomed one of the three giant suns that lay about that world. We were leaping forward straight toward it, and in an instant it had broadened across the heavens to a stupendous disk of raging crimson fire, a thunderous, titanic sun into which we seemed inevitably doomed to plunge, but as it flared across the firmament before us Korus Kan swerved the controls, and we were flashing by it, past the red star's edge and on outward through the dying universe. Traveling at a speed that was all but suicidal to use inside any universe, thrumming on at all but our utmost velocity, we reeled outward through the throngs of dead and dying stars about us, while behind us at a speed that matched our own our ten pursuers came relentlessly on, with the five hundred-odd ships that we had seen rising from the serpent-city following us in turn. Out--out--the minutes of that mad outward flight through the dying universe are but a confused, strange memory of a wild, awful race through the massed dead and dying stars that thronged thick about us, and between which we drove with such terrific swiftness that hardly could we glimpse them in passing save on our space-chart. On that chart I saw a close-massed cluster of dark suns full before us, saw the Antarian swing the ship lightning-like sidewise to avoid it, then sharply drive the controls back again as before us a crimson-flaming star about which turned countless worlds of the serpent-people loomed before us. Out--out--flashing crazily on past crimson sun and thundering dark-star, through the massed suns of great dead and dying clusters and past far-swinging planets, with the ten long ships behind clinging remorselessly to us--out--out--until far ahead there became visible across all the heavens before us the wavering pale blue tight of the great vibration-wall that encircled this universe. Out between the last of the dying universe's dark and dying suns we were racing, toward that mighty wall, and as we leapt forward I pointed toward it. "The space-forts!" I exclaimed. "Make for the opening between them, Korus Kan--and slacken speed a little!" Straight toward the two great metal structures set in the pale blue-shining wall we leapt, two huge fortresses of gleaming metal from whose narrow openings came brilliant white light, whose mighty death-beam tubes swung threateningly out toward the space between them, the single vibrationless opening in the vast and impenetrable vibration-wall. They had been warned, were ready for us, we knew, and knew too that not even by a miracle could our ship run between those towering forts without coming under the deadly beams, yet still toward them we leapt, at a speed slackened a little, now, while after us like leaping things of prey came the ten ships, rapidly overhauling us, flashing closer each moment.
