"When we finally hurtled from the black void into your universe, we found what we had only dared hope for: a young universe, with many planets and cooling worlds rich in radium ores, the only element in your scale that can help to replenish our vanishing energy. Half your universe we have already deprived of its ores. Your Earth has more that we want. Then we shall continue on our way, to loot the rest of the worlds, before passing on to another universe. We are a planet without a universe. We will wander and pillage until we find a universe like the one we come from, or until Xlarbti itself disintegrates and we perish. * * * * * "We could easily wipe out all the dwellers on Earth and mine the ores ourselves. But that would be a needless waste of our powers, for since you can not defy us, and since the desire for life burns as high in you as in us and as it does in all sensate things in all universes, your people will save themselves from death and save us from wasting energy by mining the ores for us. What happens afterwards, we do not care. "The seven new suns that you saw were dead worlds that we used as buffers to slow down Xlarbti. The full strength of our repulsion-force directed against any single world necessarily turns it into a liquid or gaseous state depending on various factors. Your planet Neptune was pulled out of the solar system by the attraction of Xlarbti's mass. The flame-paths, as you call them, are directed streams of energy for different purposes: the one to the sun supplies us, for instance, with heat, light, and electricity, which in turn are stored up for eventual use. "The orange-ray that you felt is one of our achievements. It is similar to the double-action pumps used in some of your sulphur mines, whereby a pipe is inclosed in a larger pipe, and hot water forced down through the larger tubing returns sulphur-laden through the central pipe. The orange-ray instantaneously dissolves any portable object up to a certain size, propels it back to Xlarbti through its center which is the reverse ray, and here reforms the object, just as you were recreated on the disk that you stood on when you regained consciousness. "But I have not enough time to explain everything on Xlarbti to you; nor would you comprehend it all if I did. Your stay is almost up. "In that one control-panel lies all the power that we have mastered," boasted Garboreggg with supreme egotism. "It connects with the individual controls throughout Xlarbti." "What is the purpose of some of the levers?" asked Phobar, with a desperate hope in his thoughts. * * * * *
