Tourists to Terra

They came from a far sun in a distant time, seeking thrills on alien planets. Earth was their latest stop and its puny humans promised good sport!
Diomed of Argos, son of Tydeus, drew his sword with a shout and rushed forward to finish off his Trojan opponent before help could arrive. Suddenly he stopped and threw up a shielding arm before his eyes. When he could see again, one who could only have been Aphrodite, Goddess of love and beauty stood between him and the unconscious enemy. She was dressed as though for the bridal room, her Goddess body, breathtakingly beautiful, revealed through the transparent robe she wore. She was attired for love, but held a short sword in her hand.
Aphrodite smiled at him in derision. Now, then, Prince of Argos, would you fight the Gods? She advanced the sword, half mockingly.
But the Greek was mad with bloodlust, half crazed with his day's victories; he snatched up his spear, muttering, Pallas Athene aids me, and rushed her.
Her eyes widened, fear flashing in them, and she began to rise from the ground. The barbaric spear flashed out and ripped her arm; blood flowed and she dropped the sword, screaming.
Diomed heard a voice call urgently, Go back! Go back immediately to— And the Goddess Aphrodite disappeared.
He whirled to face the newcomer and saw another God confronting him. The extent of his action was beginning to be realized but Diomed had gone too far to turn back now; he charged his new opponent, shield held high and sword at the ready. The God lifted his hand, sending forth a bolt of power that brought the Greek to his knees.
Diomed's eyes were filled with sudden fear and despair. Phoebus Apollo, he quavered.
The God was scornful. Beware, Diomed, he said. Do not think to fight with Gods.
The Greek cowered before him.
Later, in the invisible space ship, hovering five hundred feet above the battle, Cajun faced her, his features impassive and his tone of voice faultless. He was boiling with rage beneath his courtesy.
