Warrior of Two Worlds By MANLY WADE WELLMAN He was the man of two planets, drawn through the blackness of space to save a nation from ruthless invaders. He was Yandro, the spoken by so many reviving unfortunates through the ages: "Where am I?" And at once there was an answer: " You lie upon the world Dondromogon. " I knew the language of that answer, but where it came from—above, knuckled dust from my eyes. "How did I get here?" I demanded of the speaker. "It was ordered—by the Masters of the Worlds—that you should be brought from your own home planet, called Earth in the System of the star called Sun. Do you remember Earth?" "Who am I?" Dondromogon." "Destined—leadership—" I began to repeat, and fell silent. I had need to think. The voice was telling me that I had been snatched from worlds away, for a specified purpose here on whatever windswept planet Dondromogon might be. "Birth and beginning—destined leadership—" Fantastic! And yet, for all I could say to the contrary, unvarnishedly "Dondromogon?" I mumbled. "The name is strange to me." birth. One face of Dondromogon ever looks to the light and heat, Dondromogon wavers on its axis, there are two lunes of its surface mighty gales ... the voice was to be heard again: Dondromogon was found and settled long ago, by adventurers from afar. of the Masters ." The voice became grand. "Suffice it that you were needed, and that the time was ripe. There is a proper time, like a The voice spoke no more. I had not the time to wonder about it. I got called Dondromogon, what manner of intelligent life bade defiance to heat and cold and storm, and built these stout structures, and now laid hands—were they hands indeed?—upon me? I swung around, setting my broad-faced middle-aged fellow. "Don't lie any more than you can help." "And leave this gate unguarded?" demanded the other. "Sound the conduct me to your commander. I can show him that I'm no spy or enemy." had first spoken. Then, to his comrade: "No reward, then." "Quiet, or I'll roast you," I told him. "What's this?" The challenge was clear, rich, authoritative. Someone else had come, "Doriza—a gentlewoman of the guard. My inspection tour brought me by She made a gesture of salute, hand at shoulder height, and reported the "Stranger," he said to me, "can you think of no better tale to tell "What proof have I?" I demanded. "On this world of yours—Dondromogon, He broke off, and wheeled on the attendant who had led him in. "To my study," he commanded. "On the shelf behind my desk, bring the great gold-bound book that is third from the right." Then he turned back, and bowed toward me. "Surely you are Yandro, the Conquering Stranger," he said, intoning as if in formal prayer. "Pardon these short-sighted The other made a little grimace. "This may be Yandro, though I'm a souls to worship, not to study. If indeed he is Yandro," and he was "Who might Yandro be?" I demanded, very uncomfortable in my bonds and come equipped with all plausible knowledge. As it is—" "As it is, he may remember that the Conquering Stranger is foretold great champion come among us in the flesh, as was foretold of ancient time by the First Comers!" Doriza and the officer crossed to his side, snatching the book. Their real respect and shyness this time. "If you are Yandro himself, you can "Forgive me, great Yandro," said the officer thickly. "I did not know." They rose, but stood off respectfully. The officer spoke first. "I am Rohbar, field commander of this defense position," he said with crisp respect. "Sporr is a mystic doctor, full of godly wisdom. Doriza, a junior officer and chief of the guard. And you—how could you know?—are sent by the First Comers to save us from our enemies." "Enemies?" I repeated. "The Newcomers," supplemented Doriza. "They have taken the "Other Side" of Dondromogon, and would take our side as well. We defend ourselves "Follow me, deign to follow me," Sporr said. "Your clothing, your level of light and sound. "Our cities are below ground," he quavered. "Whipped by winds above, we must scrabble in the depths for life's necessities—chemicals to transmute into food, to weave into clothing, to weld into tools and "I have arranged for that," Sporr began, then fell silent, fingers "Arranged food for me?" I prompted sharply. "As if you know I had come? "Pardon, great Yandro," babbled Sporr. "I was saying that I arranged food, as always, for whatever guest should come. Please follow." of which Sporr spoke. "It is indeed Yandro, our great chief," he mumbled. Then he turned and "I announce," he intoned into it. "I announce, I, Sporr, the reader and fore-teller of wisdom. Yandro is with us, he awaits his partners and "I serve Yandro," she vowed tremulously. "Now and forever—and happy that I was fated to live when he returned for the rescue of all Dondromogon." felt. "Come with me. There is still much that I do not understand." "I am Yandro's orderly and helper," she said. Rising, she ranged herself at my left hand. "Will Yandro come this way? He will be awaited labyrinth, but Doriza guided me without the slightest hesitation past of Dondromogon's sunlit face is ever rising, and the cold air from the dark side comes rushing under to fill the vacuum. Naturally, our strip of twilight country is never free of winds too high and fierce to fight. No crops can grow outside, no domestic animals flourish. We must windswept? Why can two people not join forces and face toil and nature together? They should fight, not each other, but the elements." Doriza had no answer that time, but Sporr spoke up behind us: "Great Yandro is wise as well as powerful. But the Newcomers do not want to help, not even to conquer. They want to obliterate us. There is nothing to do—not for lifetimes—but to fight them back at the two poles." "Doriza, gentlewoman of the guard, conducts Yandro, the Conquering My mind flew back to the two scrubby, venial guardsmen who had first welcomed me to stuffy Rohbar, the commander Doriza now spoke to the gathering: "Yandro, folk of the Council! He deigns to give you audience." Yandro! They all spoke the name in chorus, and bowed toward me. Silence then, a silence which evidently I must break. I broke it: they true?" "The tenth part of the wonders which concern mighty Yandro have not been told," intoned Sporr, ducking his bearded head in a bow, but "I am Gederr, senior of this Council," he purred. "If Yandro permits, I will speak simply. Our hopes have been raised by Yandro's return—the encompass his destruction." He grinned, and licked his full lips.
