* * * * * That night the Golden City made savage preparation for war. Ships were loaded and ranged in order. Crews armed themselves, and helped in the loading and arming of other ships. Oddly enough, it was to Tommy that men came to ask if the directing apparatus for the Death Mist should be carried. The Death Mist could, of course, be used as a gas alone, drifting with the wind, or it could be directed from a distance. This had been done on Earth, with the directional impulses sent blindly down the Tube merely to keep the Mist moving always. The controlling apparatus could be carried in a monster freight plane. Tommy ordered it done. Also he had the captured planes from Rahn refitted for flight by replacing their smashed propelling grids. Fresh crews of men for these ships organized themselves. When the fleet took off there was only darkness in all the world. The unfamiliar stars above shone bright and very near as Tommy's ship, leading, winged noiselessly up and down and straight away from the play of prismatic lights above the city. Behind him, silhouetted against that many-colored glow, were the angular shapes of many other noiseless shadows. The ornithopters with their racket would start later, so the planes would be soaring above Rahn before their presence was even suspected. The rest of the fleet flew in darkness. * * * * * The flight above the jungle would have been awe-inspiring at another time. There were the stars above, nearer and brighter than those of Earth. There was no Milky Way in the firmament of this universe. The stars were separate and fewer in number. There was no moon. And below there was only utter, unrelieved darkness, from which now and again beast-sounds arose. They were clearly audible on board the silent air fleet. Roarings, bellowings, and hoarse screamings. Once the ships passed above a tumult as of unthinkable monsters in deadly battle, when for an instant the very clashing of monstrous jaws was audible and a hissing sound which seemed filled with deadly hate. Then lights--few of them, and dim ones. Then blazing fires--Ragged Men, camped without the walls of Rahn or in some gold-walled courtyard where the jungle thrust greedy, invading green tentacles. The air fleet circled noiselessly in a huge batlike cloud. Then things came racing from the darkness, down below, and there was a tumult and a shouting, and presently the hilarious, insanely gleeful uproar of the Ragged Men. Tommy's face went gray. These were the escaped prisoners, arrived actually after the air fleet which was to demand the return of their captives. Tommy wet his lips and spoke grimly to his pilot. There were six men and many Death-Mist bombs in his ship. He was asking if communication could be had with the other ships. It was wise to let Rahn know at once that avengers lurked overhead for the captives just delivered there.
