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 he was destined to fight both sides. [Transcriber's Note: This etext was produced from 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, beneath, or indeed within me—I could not say. I lifted a hand, and 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?" And I did not know whether I remembered or not. Vague matters stirred deep in me, but I could not for certain say they were memories. I asked yet again: "Who am I?" The voice had a note of triumph. "You do not know that. It is as well, 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 true. "Dondromogon?" I mumbled. "The name is strange to me." "It is a world the size of your native one," came words of information. birth. One face of Dondromogon ever looks to the light and heat, wherefore its metals run in glowing seas. The other face is ever away in cold darkness, with its air freezing into solid chunks. But because Dondromogon wavers on its axis, there are two lunes of its surface which from time to time shift from night to day. These are habitable." My eyes were tight shut against the dust, but they saw in imagination such a planet—one-half incandescent, one-half pitchy black. From pole "War is fought between the two strips of habitable ground. War, unceasing, bitter, with no quarter asked, given or expected. Dondromogon was found and settled long ago, by adventurers from afar. wrong?" "Anyone would wish that," I replied. "But how—" "You are going to ask how you were brought here. That is the mystery of the Masters ." The voice became grand. "Suffice it that you were blocky silhouette, a building of sorts. back to a solid wall. My first glance showed me that my companions were creatures like myself—two-legged, fair-skinned men, shorter and slighter than I, but a curved stock to fit the palm of the hand, borne snugly in a holster. With such arms I had a faint sense of familiarity. "Who are you, and where are you from?" said one of the two, a broad-faced middle-aged fellow. "Don't lie any more than you can help." I felt a stirring of the hair on my neck, but kept my voice mild and level: "Why should I lie? Especially as I don't know who I am, or where I'm from, or anything that has happened longer ago than just a moment. I woke up out there in the dust storm, and I managed to come here for shelter." "He's a Newcomer spy," quoth the other. "Let's put him under arrest." "And leave this gate unguarded?" demanded the other. "Sound the studied me apprehensively. "He's big, and looks strong, even without "What's this?" The challenge was clear, rich, authoritative. Someone else had come, A woman this time, not of great height, and robust but not heavy. She "A spy," one ventured. "He pushed in, claimed he was no enemy, then tried to attack—" "They lie," I broke in, very conscious of my naked helplessness before Beyond, it gave into several passages. She chose one of them and conducted me along. "You are surely not of us," she commented. "Men I have seen who are heavier than you, but none taller. Whence came you?" I remembered the strange voice that had instructed me. "I am from a far world," I replied. "It is called—yes, Earth. Beyond that, I know nothing. Memory left me." "Stranger," he said to me, "can you think of no better tale to tell than you now offer?" "I tell the truth," was my reply, not very gracious. "You will have to prove that," he admonished me. "What proof have I?" I demanded. "On this world of yours—Dondromogon, isn't it called?—I'm no more than an hour old. Accident or shock has taken my memory. Let me have a medical examination. A scientist probably can tell what happened to put me in such a condition." "I am a scientist," offered Doriza, and came forward. Her eyes met mine, suddenly flickered and lowered. "His gaze," she muttered. bearded fellow in a voluminous robe that enfolded him in most dignified "The stranger of the prophecy!" he cried, in a voice that made us all You mystic doctors are too apt to become fuddled—" "But it is, it is!" The graybeard flourished a thin hand at me. "Look at him, you of little faith! Your mind dwells so much on material strength that you lose touch with the spiritual—" generally does, you have committed a blasphemy." 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 most respectful, "he will appreciate, like a good military mind, my caution against possible impostors." "As it is, he may remember that the Conquering Stranger is foretold against you, Sporr. You should have been able to instruct me, not I you." prove it. The prophecy even sketches a thumb-print—" And he held the book toward me. It contained a full-page likeness, in color, of myself wrapped in a men take into thought. The ears in the picture are like the ears of the real man—" "That could be plastic surgery," rejoined the officer. "Such things are artfully done by the Newcomers, and the red mantle he wears more easily assumed." Doriza shook her head. "That happens to be my cloak. I gave it to him because he was naked, and not for any treasonable masquerade. But the thumb-print—" worshipped." II They rose, but stood off respectfully. The officer spoke first. "I am 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 body for the first time—towered rather bluffly, with great breadth of chest and shoulder, and legs robust enough to carry such bulk.

"It is necessary that we live like this," she explained. "The hot air 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 fight. No crops can grow outside, no domestic animals flourish. We must pen ourselves away from the sky and soil, with stout walls and heavy as tall as I and nobly proportioned, with hair of a red that would be "You honor me," I told him. "Yet I still know little. It seems that I am expected to aid and lead and save the people of this world called Dondromogon. But I must know them before I can help."
