Humming, throbbing, droning, on through the void our great fleet shot, force-shaft cylinders and other mechanisms clanging now beneath us as our Andromedan crew cleared the decks below for action. With every hour, every moment, the galaxy's stars were shining in greater splendor ahead, a giant belt of suns across the firmament before us. My eyes roved across them, from the yellow splendor of Capella to the white brilliance of Rigel, and then something of emotion rose in me as they shifted to Antares, the great crimson star that had been Korus Kan's home sun. But my eyes hardened again as they turned toward the Cancer cluster, a great ball of suns glowing in resplendent glory at the galaxy's edge before us; for well I knew that upon the thronging worlds of its clustered suns the countless races of the serpent-creatures were gathered now, completing the gigantic death-beam cone with which they would sweep out to annihilate all life in our galaxy save themselves. Straight toward that ball of suns our fleet was leaping, and now Jhul Din turned toward me. "You're going to drive with our fleet straight into the cluster itself?" he asked, and I nodded grimly. "It's our only chance," I said. "All the serpent-hordes are on the worlds inside it, and we've got to reach it to destroy that great cone before they finish it." Now the galaxy's flaring suns filled the heavens before us as our mighty armada raced in through the outer void toward them, the Cancer cluster flaming ahead in all the blinding glory of its gathered suns, those suns appearing on the upper part of our space-chart as a mass of glowing little circles, toward which our vast swarm of ship-dots was speeding. Minutes more of our terrific speed would see us reaching that cluster, I knew, and I turned toward the bank of keys before me to shift our great fleet's mass into a formation that would allow us to pour down into that ball of suns in our great attack. But as I did so, as I reached toward those keys, there came from Jhul Din a cry that held me rigid. He was gazing up toward the space-chart, and pointing. "Look--in the cluster!" he cried. "Those dots--those ships----!"
