Not as it was now, swift and easy, far outrunning the velocity of light. Science had the techniques even then to build and power the fast ships, but they were useless. Man could not survive the ultra-speeds. They had to go as they went between the planets, slowly. Four generations lived and died within the close confines of that first feeble forerunner of the Vardda fleets, men and women dedicated in themselves and their children to the conquest of the greatest barrier humanity had ever crossed. And they crossed it. Slowly, painfully, exposed to all the dangers of unknown radiations and unexplored, uncharted wilderness in its most ultimate sense, exposed to the most terrible loneliness and isolation that living beings had ever endured, they toiled their way to a landing on the world of another star and then--and this, to Trehearne, seemed the most incredible bravery of all--they took off again for Llyrdis, which to this intermediate generation was only a name and a tradition, and which they knew they would never live to see. Orthis was born during this return voyage, twenty-two years out from the planet he was taught to regard as home, though he had no knowledge of planets, nor of any life except that of the ship that moved apparently forever through the night of deep space. His ears must have been attuned only to that outer silence, his sight to the darkness and the far-off stars. To wind and rain, to sunlight and warm grass, to beasts and birds and the faces of many people, he was a stranger. And a stranger he remained. "He could not endure to be planet-bound, after living all his life in space. He built his laboratory ship and worked in it, cruising where he wished and almost alone, for another fifteen years. Then, when he was thirty-seven, he announced his discovery--the birth of Galactic Man, the inception of the Vardda. "Orthis refused to give to anyone the whole secret of his mutational process, believing that it was too dangerous in inexpert hands. He himself constructed the apparatus and used it, sowing with his own hands the seed of the Vardda race that would flower in the next generation. And at that time, he was revered by the people of Llyrdis almost as a demigod. But within the next year the troubles arose that almost split the Llyrdian State, and brought Orthis eventually into disgrace. He had given his discovery first to his own people, and now...."
