The planet she had come from is unimportant, suffice to say their technology had conquered space over a thousand years ago. For over half that time they had subjugated neighboring worlds until their rule had spread to the borders of Earth. Scouting ships had been spying on Earth for the past two centuries and had brought back alarming reports concerning the rapidly expanding technology of this planet. Soon after the aliens had discovered the secret of space flight had come the added knowledge planets could be conquered by other than the force of arms. Psychological warfare had been developed to a fantastic degree, making weapons more potent than any bombs of fissionable material. There she stood, a monument to her creators. Eve, soon to be conqueror of the planet Earth. To attempt description of her beauty would be an impossibility, for the languages of man do not contain the necessary word-symbols to express the utter perfection of her face and form. To each man she would appear different, for he would see in her the substance of his unconscious desires for the woman he had never dreamed might exist. For this purpose the scientists had labored in their laboratories for nearly a half century, and now she would justify the time and effort spent in her creation. Gently, she smiled at the man waiting below, and despite the special conditioning he had undergone, and the drugs he took with careful regularity for added protection, he almost surrendered to the impulse to throw himself at her feet; to beg for only the privilege to serve her, to obey her, and to worship her. Out of the entire space fleet, he, Commander Ydnas, after extensive psychological testing, had been selected for this task. The three months of conditioning had passed rapidly, his response to the treatments had been better than they had dared to hope. In the two weeks of their flight he had been unaffected by her presence, and now upon landing he was beginning to feel the strain he was under. He wondered what would have happened had it not been for the added help of the drugs? * * * * * His face betrayed none of the anxiety he now felt. It was an impassive mask, his body was ramrod tense and erect. She came down the steps gracefully, her litheness would have made the movements of a cat seem awkward and clumsy. Both had been thoroughly trained in the languages needed to carry out the plan of invasion, English and Russian. First, the large continent of North America would be disarmed at her command; and then they would move across the large body of water to Europe. Russia would be their initial target there. The invasion timetable called for a three month campaign, and then Eve would be removed from the planet before the occupation fleet from the mother world would land. Not a man would be lost, nor a space ship damaged, and yet the planet's rich potential would be theirs for the taking.
