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 Stranger of the Prophecy—and he found that he was destined to fight both sides. [Transcriber's Note: This etext was produced from You lie upon the world Dondromogon. "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?" Dondromogon." 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." "It is a world the size of your native one," came words of information. "Around a star it spins, light-years away from the world of your 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 to pole on opposite sides ran the two twilight zones, widest at the equators like the outer rind of two slices of melon. Of course, such areas, between the hot and cold hemispheres, would be buffeted by mighty gales ... the voice was to be heard again: "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. Now come invaders, to reap the benefits of discovery and toil." A pause. "You find that thought unpleasant? You wish to right that wrong?" called Dondromogon, what manner of intelligent life bade defiance to heat and cold and storm, and built these stout structures, and now laid My first glance showed me that my companions were creatures like myself—two-legged, fair-skinned men, shorter and slighter than I, but "There's a bigger reward for capture than for warning," objected his friend in turn, "and whoever comes to take this man will claim 'capture.' I'll guard here, and you take him in, then we'll divide—" "No. Yours is the idea. I'll guard and you take him in." The second man prevent it burning me, and tried to break away, but my bonds were too much for me. "Let me out of this," I growled, and kicked at the man with my still heavily. Triumphant laughter came from both adversaries. Then: "What's this?" "What proof have I?" I demanded. "On this world of yours—Dondromogon, The other made a little grimace. "This may be Yandro, though I'm a "Who might Yandro be?" I demanded, very uncomfortable in my bonds and one side a thumb-print, or a drawing of one, in black. "Behold," Doriza was saying, "matters which even expert identification men take into thought. The ears in the picture are like the ears of the in several places with the glowing end of the rod. The coils dropped three gazed. 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 at the poles. Now," and her voice rang joyously, "you will lead us to defeat and crush them utterly!" 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 weapons—" fierce fighting—but surely no inspirational leader or savior of a distressed people. Outside stood Doriza. Her blue eyes met mine, and her lips moved to kissing it. "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." herself at my left hand. "Will Yandro come this way? He will be awaited mixture of awe and brightness. "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 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 pen ourselves away from the sky and soil, with stout walls and heavy sunken parapets. Our deep mines afford every element for necessities of life." I looked at my garments, and hers. There were various kinds of fabric, which I now saw plainly to be synthetic. "The other side, where those you call the Newcomers dwell and fight," I reminded. "Is it also 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 in the nation I seemed destined to save, my work was cut out for me. Not that they really seemed stupid—none had the look, or the subsequent action, of stupidity. But they were not pleasant. Their dozen pairs of eyes fixed me with some steadiness, but with no frankness anywhere. One man had a round, greedy-seeming face. Another was too narrow and cunning to look it. Of the women, one was nearly inspiring were it not so blatantly dyed. The other was a little wisp of a brunette, with teeth too big for her scarlet mouth and bright eyes like some sort of a rodent. They all wore jewelry. Too much jewelry. Doriza—no, she was not like these "Yandro, folk of the Council! He deigns to give you audience." Yandro! "The tenth part of the wonders which concern mighty Yandro have not fixing me with his wise old eyes. One of the group, called Council by Doriza, now moved a pace forward. He was the greedy-faced man, short but plump, and very conscious of will speak simply. Our hopes have been raised by Yandro's return—the caused fear and ruin. But it pleased our fortune-bringing stars to encompass his destruction." He grinned, and licked his full lips. "Now, even as they are without their battle-leader, so we have ours." "You honor me," I told him. "Yet I still know little. It seems that I Dondromogon. But I must know them before I can help." The others followed suit—the Council on their range of chairs, Doriza
