This was all fine with Naog. He knew that he would have his place in the clan in due time. He worked hard to learn all the skills of manhood--how to fight with any weapon; how to paddle his dragonboat straight on course, yet silently; how to recognize the signs of the seasons and the directions of the stars at different hours of the night and times of the year; which wild herbs were good to eat, and which deadly; how to kill an animal and dress it so it would keep long enough to bring home for a wife to eat. Twerk often said that his son was as quick to learn things requiring wit and memory as to learn skills that depended only on size and strength and quickness.

  What Twerk did not know, what no one even guessed, was that these tasks barely occupied Naog's mind. What he dreamed of, what he thought of constantly, was how to become a great man so that his name could be spoken with solemn honor instead of a smile or laughter.

  One of Naog's strongest memories was a visit to the Great Derku in the holy pond at the very center of the great circular canals that linked all the Derku people together. Every year during the mud season, the first dredging was the holy pond, and no slaves were used for THAT. No, the Derku men and women, the great and the obscure, dredged the mud out of the holy pond, carried it away in baskets, and heap it up in piles that formed a round lumpen wall around the pond. As the dry season came, crocodiles a-wandering in search of water would smell the pond and come through the gaps in the wall to drink it and bathe in it. The crocodiles knew nothing of danger from coming within walls. Why would they have learned to fear the works of humans? What other people in all the world had ever built such a thing? So the crocodiles came and wallowed in the water, heedless of the men watching from trees. At the first full moon of the dry season, as the crocodiles lay stupidly in the water during the cool of night, the men dropped from the trees and quietly filled the gaps in the walls with earth. At dawn, the largest crocodile in the pond was hailed as Great Derku for the year. The rest were killed with spears in the bloodiest most wonderful festival of the year.

  The year that Naog turned six, the Great Derku was the largest crocodile that anyone could remember ever seeing. It was a dragon indeed, and after the men of raiding age came home from the blood moon festival full of stories about this extraordinary Great Derku, all the families in all the clans began bringing their children to see it.

  "They say it's a crocodile who was Great Derku many years ago," said Naog's mother. "He has returned to our pond in hopes of the offerings of manfruit that we used to give to the dragon. But some say he's the very one who was Great Derku the year of the forbidding, when he refused to eat any of the captives we offered him."

  "And how would they know?" said Twerk, ridiculing the idea. "Is there anyone alive now who was alive then, to recognize him? And how could a crocodile live so long?"

  "The Great Derku lives forever," said Lewik.

  "Yes, but the true dragon is the derkuwed, the water in flood," said Twerk, "and the crocodiles are only its children."

  To the child, Naog, these words had another meaning, for he had heard the word DERKUWED far more often in reference to himself, as his nickname, than in reference to the great annual flood. So to him it sounded as though his father was saying that HE was the true dragon, and the crocodiles were his children. Almost at once he realized what was actually meant, but the impression lingered in the back of his mind.

  "And couldn't the derkuwed preserve one of its children to come back to us to be our god a second time?" said Lewik. "Or are you suddenly a holy man who knows what the dragon is saying?"

  "All this talk about this Great Derku being one of the ancient ones brought back to us is dangerous," said Twerk. "Do you want us to return to the terrible days when we fed manfruit to the Great Derku?

  When our captives were all torn to pieces by the god, while WE, men and women alike, had to dig out all the canals without slaves?"

  "There weren't so many canals then," said Lewik. "Father said."

  "Then it must be true," said Twerk, "if your old father said it. So think about it. Why are there so many canals now, and why are they so long and deep? Because we put our captives to work dredging our canals and making our boats. What if the Great Derku had never refused to eat manfruit? We would not have such a great city here, and other tribes would not bring us gifts and even their own children as slaves. They can come and visit our captives, and even buy them back from us. That's why we're not hated and feared, but rather

  LOVED and feared in all the lands from the Nile to the Salty Sea."

  Naog knew that his father's manhood journey had been from the Salty Sea all the way up the mountains and across endless grasslands to the great river of the west. It was a legendary journey, fitting for such a large man. So Naog knew that he would have to undertake an even greater journey. But of that he said nothing.

  "But these people talking stupidly about this being that same Great Derku returned to us again--don't you realize that they will want to put it to the test again, and offer it manfruit? And what if the Great Derku EATS it this time? What do we do then, go back to doing all the dredging ourselves? Or let the canals fill in so we can't float the seedboats from village to village during the dry season, and so we have no defense from our enemies and no way to ride our dragonboats all year?"

  Others in the clan were listening to this argument, since there was little enough privacy under normal circumstances, and none at all when you spoke with a raised voice. So it was no surprise when they chimed in. One offered the opinion that the reason no manfruit should be offered to this Great Derku was because the eating of manfruit would give the Great Derku knowledge of all the thoughts of the people they ate. Another was afraid that the sight of a powerful creature eating the flesh of men would lead some of the young people to want to commit the unpardonable sin of eating that forbidden fruit themselves, and in that case all the Derku people would be destroyed.

  What no one pointed out was that in the old days, when they fed manfruit to the Great Derku, it wasn't JUST captives that were offered. During years of little rain or too much rain, the leader of each clan always offered his own eldest son as the first fruit, or, if he could not bear to see his son devoured, he would offer himself in his son's place--though some said that in the earliest times it was always the leader himself who was eaten, and they only started offering their sons as a cowardly substitute. By now everyone expected Twerk to be the next clan leader, and everyone knew that he doted on his Glogmeriss, his Naog-to-be, his Derkuwed, and that he would never throw his son to the crocodile god. Nor did any of them wish him to do so. A few people in the other clans might urge the test of offering manfruit to the Great Derku, but most of the people in all of the tribes, and all of the people in Engu clan, would oppose it, and so it would not happen.

  So it was with an assurance of personal safety that Twerk brought his firstborn son with him to see the Great Derku in the holy pond.

  But six-year- old Glogmeriss, oblivious to the personal danger that would come from the return of human sacrifice, was terrified at the sight of the holy pond itself. It was surrounded by a low wall of dried mud, for once the crocodile had found its way to the water inside, the gaps in the wall were closed. But what kept the Great Derku inside was not just the mud wall. It was the row on row of sharpened horizontal stakes pointing straight inward, set into the mud and lashed to sharp vertical stakes about a hand's-breadth back from the point. The captive dragon could neither push the stakes out of the way nor break them off. Only when the floodwater came and the river spilled over the top of the mud wall and swept it away, stakes and all, would that year's Great Derku be set free. Only rarely did the Great Derku get caught on the stakes and die, and when it happened it was regarded as a very bad omen.

  This year, though, the wall of stakes was not widely regarded as enough assurance that the dragon could not force his way out, he was so huge and clever and strong. So men stood guard constantly, spears in hand, ready to prod the Great Derku and herd it back into place, should it come dangerously close to escaping.

  The sight of spikes and spears was alarming enough, for it looked like war to young Glogmeriss. But he soon forgot those puny sticks when he caught sight of the Great Derku himself, as he shambled up on the muddy, grassy shore of the pond. Of course Glogmeriss had seen crocodiles all his life; one of the first skills any child, male or female, had to learn was how to use a spear to poke a crocodile so it would leave one's dragonboat--and therefore one's arms and legs--in peace. This crocodile, though, this dragon, this god, was so huge that Glogmeriss could easily imagine it swallowing him whole without having to bite him in half or even chew.

  Glogmeriss gasped and clung to his father's hand.

  "A giant indeed," said his father. "Look at those legs, that powerful tail. But remember that the Great Derku is but a weak child compared to the power of the flood."

  Perhaps because human sacrifice was still on his mind, Twerk then told his son how it had been in the old days. "When it was a captive we offered as manfruit, there was always a chance that the god would let him live. Of course, if he clung to the stakes and refused to go into the pond, we would never let him out alive--we poked him with our spears. But if he went boldly into the water so far that it covered his head completely, and then came back out alive and made it back to the stakes without the Great Derku taking him and eating him, well, then, we brought him out in great honor. We said that his old life ended in that water, that the man we had captured had been buried in the holy pond, and now he was born again out of the flood.

  He was a full member of the tribe then, of the same clan as the man who had captured him. But of course the Great Derku almost never let anyone out alive, because we always kept him hungry."

  "YOU poked him with your spear?" asked Glogmeriss.

  "Well, not me personally. When I said that WE did it, I meant of course the men of the Derku. But it was long before I was born. It was in my grandfather's time, when he was a young man, that there came a Great Derku who wouldn't eat any of the captives who were offered to him. No one knew what it meant, of course, but all the captives were coming out and expecting to be adopted into the tribe.

  But if THAT had happened, the captives would have been the largest clan of all, and where would we have found wives for them all? So the holy men and the clan leaders realized that the old way was over, that the god no longer wanted manfruit, and therefore those who survived after being buried in the water of the holy pond were NOT adopted into the Derku people. But we did keep them alive and set them to work on the canals. That year, with the captives working alongside us, we dredged the canals deeper than ever, and we were able to draw twice the water from the canals into the fields of grain during the dry season, and when we had a bigger harvest than ever before, we had hands enough to weave more seedboats to contain it. Then we realized what the god had meant by refusing to eat the manfruit. Instead of swallowing our captives into the belly of the water where the god lives, the god was giving them all back to us, to make us rich and strong. So from that day on we have fed no captives to the Great Derku. Instead we hunt for meat and bring it back, while the women and old men make the captives do the labor of the city. In those days we had one large canal. Now we have three great canals encircling each other, and several other canals cutting across them, so that even in the dryest season a Derku man can glide on his dragonboat like a crocodile from any part of our land to any other, and never have to drag it across dry earth. This is the greatest gift of the dragon to us, that we can have the labor of our captives instead of the Great Derku devouring them himself."

  "It's not a bad gift to the captives, either," said Glogmeriss. "Not to die."

  Twerk laughed and rubbed his son's hair. "Not a bad gift at that,"

  he said.

  "Of course, if the Great Derku really loved the captives he would let them go home to their families."

  Twerk laughed even louder. "They have no families, foolish boy," he said. "When a man is captured, he is dead as far as his family is concerned. His woman marries someone else, his children forget him and call another man father. He has no more home to return to."

  "Don't some of the ugly-noise people buy captives back?"

  "The weak and foolish ones do. The gold ring on my arm was the price of a captive. The father-of-all priest wears a cape of bright feathers that was the ransom of a boy not much older than you, not long after you were born. But most captives know better than to hope for ransom. What does THEIR tribe have that we want?"

  "I would hate to be a captive, then," said Glogmeriss. "Or would YOU

  be weak and foolish enough to ransom me?"

  "You?" Twerk laughed out loud. "You're a Derku man, or will be. We take captives wherever we want, but where is the tribe so bold that it dares to take one of US? No, we are never captives. And the captives we take are lucky to be brought out of their poor, miserable tribes of wandering hunters or berry-pickers and allowed to live here among wall-building men, among canal- digging people, where they don't have to wander in search of food every day, where they get plenty to eat all year long, twice as much as they ever ate before."

  "I would still hate to be one of them," said Glogmeriss. "Because how could you ever do great things that everyone will talk about and tell stories about and remember, if you're a captive?"

  All this time that they stood on the wall and talked, Glogmeriss never took his eyes off the Great Derku. It was a terrible creature, and when it yawned it seemed its mouth was large enough to swallow a tree. Ten grown men could ride on its back like a dragonboat. Worst of all were the eyes, which seemed to stare into a man's heart. It was probably the eyes of the dragon that gave it its name, for DERKU

  could easily have originated as a shortened form of DERK-UNT, which meant "one who sees." When the ancient ancestors of the Derku people first came to this floodplain, the crocodiles floating like logs on the water must have fooled them. They must have learned to look for eyes on the logs. "Look!" the watcher would cry. "There's one with eyes! Derk-unt!" They said that if you looked in the dragon's eyes, he would draw you toward him, within reach of his huge jaws, within reach of his curling tail, and you would never even notice your danger, because his eyes held you. Even when the jaws opened to show the pink mouth, the teeth like rows of bright flame ready to burn you, you would look at that steady, all-knowing, wise, amused, and coolly angry eye.

  That was the fear that filled Glogmeriss the whole time he stood on the wall beside his father. For a moment, though, just after he spoke of doing great things, a curious change came over him. For a moment Glogmeriss stopped fearing the Great Derku, and instead imagined that he WAS the giant crocodile. Didn't a man paddle his dragonboat by lying on his belly straddling the bundled reeds, paddling with his hands and kicking with his feet just as a crocodile did under the water? So all men became dragons, in a way.

  And Glogmeriss would grow up to be a large man, everyone said so.

  Among men he would be as extraordinary as the Great Derku was among crocodiles. Like the god, he would seem dangerous and strike fear into the hearts of smaller people. And, again like the god, he would actually be kind, and not destroy them, but instead help them and do good for them.

  Like the river in flood. A frightening thing, to have the water rise so high, sweeping away the mud hills on which they had built the seedboats, smearing the outsides of them with sun-heated tar so they would be watertight when the flood came. Like the Great Derku, the flood seemed to be a destroyer. And yet when the water receded, the land was wet and rich, ready to receive the seed and give back huge harvests. The land farther up the slopesof the mountains was salty and stony and all that could grow on it was grass. It was here in the flatlands where the flood tore through like a mad dragon that the soil was rich and trees could grow.

  I will BE the Derkuwed. Not as a destroyer, but as a lifebringer.

  The real Derku, the true dragon, could never be trapped in a cage as this poor crocodile has been. The true dragon comes like the flood and tears away the walls and sets the Great Derku crocodile free and makes the soil wet and black and rich. Like the river, I will be another tool of the god, another manifestation of the power of the god in the world. If that was not what the dragon of the deep heaven of the sea intended, why would he have make Glogmeriss so tall and strong?

  This was still the belief in his heart when Glogmeriss set out on his manhood journey at the age of fourteen. He was already the tallest man in his clan and one of the tallest among all the Derku people. He was a giant, and yet well-liked because he never used his strength and size to frighten other people into doing what he wanted; on the contrary, he seemed always to protect the weaker boys. Many people felt that it was a shame that when he returned from his manhood journey, the name he would be given was a silly one like Naog. But when they said as much in Glogmeriss's hearing, he only laughed at them and said, "The name will only be silly if it is borne by a silly man. I hope not to be a silly man."

  Glogmeriss's father had made his fame by taking his manhood journey from the Salty Sea to the Nile. Glogmeriss's journey therefore had to be even more challenging and more glorious. He would go south and east, along the crest of the plateau until he reached the legendary place called the Heaving Sea, where the gods that dwelt in its deep heaven were so restless that the water splashed onto the shore in great waves all the time, even when there was no wind. If there was such a sea, Glogmeriss would find it. When he came back as a man with such a tale, they would call him Naog and none of them would laugh.

  Kemal Akyazi knew that Atlantis had to be there under the waters of the Red Sea; but why hadn't Pastwatch found it? The answer was simple enough. The past was huge, and while the TruSite I had been used to collect climatalogical information, the new machines that were precise enough that could track individual human beings would never have been used to look at oceans where nobody lived. Yes, the Tempoview had explored the Bering Strait and the English Channel, but that was to track long-known-of migrations. There was no such migration in the Red Sea. Pastwatch had simply never looked through their precise new machines to see what was under the water of the Red Sea in the waning centuries of the last Ice Age. And they never WOULD look, either, unless someone gave them a compelling reason.
