When the first dark star was so equipped I gave it its tests. Standing with Korus Kan and Jhul Din at its controls, and with Lacq Larus watching beside us, I turned on the power. The huge dead sun moved away through space in perfect answer to its controls. I speeded it up, slowed it, turned sharply and circled it around a few suns to make sure of its tractability. Then we tried the attractive beam. Korus Kan handled the controls of this, and with it we hooked onto a medium-size sun. Then as I started our dark star forward through space again we found that we towed the sun steadily along with us. "It's successful!" Lacq Larus exclaimed. "And all the others will be ready soon!" "As soon as they're ready we'll start for the galaxy of the machines," he said, "before they've time to come back here again." Rapidly the others of the hundred dark stars were equipped and tested. Lacq Larus took one as the flagship of the stupendous fleet. At his order we drove our dark-star chariot outside the galaxy's edge and there the whole hundred massed together. We formed in columns of ten, the dark star of Lacq Larus taking a position a little ahead of the rest of us. Then Lacq Larus gave an order on the space-phones which had been fitted to all our worlds, and as one our fleet of a hundred dark stars began to move through space toward the soft, hazy patch of light that was the distant galaxy of the machines. Our caravan was on its way to retrieve our stolen suns, in the mightiest venture yet undertaken by the Interstellar Patrol. * * * * * Jhul Din was exultant. "By the suns, this is better than driving ships!" he exclaimed. "Driving dark stars to battle!" "There'll be all the battle you want when we reach the galaxy of the machines," I told him grimly. "You're going to follow out our original plan?" I asked Lacq Larus on the space-phone, and he answered in the affirmative. "It's a risky one, but I believe it is the best one." We hurtled on in the void toward the distant galaxy of the machines. Slowly, very slowly despite our immense speed, it grew in apparent size. It grew from a little patch of light to a cloud of tiny points of light. And as it grew, our own galaxy shrank astern. Korus Kan and Jhul Din and I relieved each other at the controls of the dark star. We kept our place in the general formation, the dark star of Lacq Larus still leading. There was something magnificent and awful in this cosmic march of our hundred dead suns through space to retrieve our stolen suns and take vengeance on those who had stolen them. The galaxy of the machine-people grew into a great cloud of stars across the firmament. With eager eyes we surveyed it. "It seems about the same size as our own galaxy," Lacq Larus commented. "But it has far more dying suns than ours."
