Even as the bolts had blasted the pyramid's top our cruisers had shot with the velocity of thousands of light-speeds out from the central world and those about it, out across the comet's heart toward the circular opening through the coma, through that passage of crimson death at awful speed and out into space behind the comet as the passage closed behind us, as the tail behind the comet waned swiftly! And as our cruisers shot up above the mighty comet, we saw that it had halted in space, the awful momentum with which the old tail at the rear had driven it on balanced, opposed, by the new tail shot from its front, toward the galaxy, when Najus Nar had reversed the control! Caught between the two cosmic pressures, between the momentum and terrific speed with which the old tail drove it forward and the power with which the new tail drove it backward, the mighty coma beneath us was bulging, was spreading! Bulging outward above and below, to right and to left, its giant crimson-glowing coma dilating and breaking up between the terrific pressures from front and rear! Changing from a great sphere to a gigantic shapeless crimson mass of electrical energy, bulging out in all directions, great flashes of leaping light inside it marking the end of the great comet-worlds caught and annihilated inside its tortured mass! Out--out--it swelled, our cruisers hanging far above it, watching it grow swiftly greater, _thinner_, until in moments more where the colossal crimson comet had been was nothing but a vast, far-flung cloud of faint electrical radiance, the concentrated electrical energy that had been the giant comet and its worlds dispersed out into that huge, faint-shining cloud! The cosmic vampire that had threatened the life of our universe was gone forever! The comet-drivers had driven their comet and its worlds, at last, to death! 5 Sweeping in toward the galaxy's gathered suns, days later, our great cruiser fleet slowed, halted, hung motionless outside the galaxy's edge once more. Before us flamed great white Rigel, as it had flamed--how long it seemed before!--when Gor Han and Jurt Tul and Najus Nar had gathered in the control room of my cruiser, at the start of our mad journey toward the comet. Now that comet was but a vast, faint cloud of radiance far in the void behind us. And now, too, it was Gor Han and Jurt Tul that stood before me, in the cruiser's silent control room.
