“Later,” Madame told Claude, “when it is dark, we will be able to see Finiah’s lights against the northern sky. It stands on a promontory jutting into the Rhine. It is not a large city, but it is the oldest of all the Tanu settlements and they have illuminated it with great splendor.”

“Why did they migrate southward, out of this area?” Claude asked. “From what I’ve been told, most of the Tanu cities are down around the Mediterranean, with this northern country left pretty much to the Firvulag.”

“A very warm climate is more to the Tanu taste. I believe that the division of territory between the two groups reflects a very ancient pattern, perhaps one that goes back to the origins of the dimorphic Race. One might imagine a world of singular niggedness where highland and lowland forms evolved, perhaps interdependent yet antagonistic, With the coming of high civilization and the eventual migration of the race to other worlds in their galaxy, these ancient tensions would be sublimated. But it would seem that Tanu and Firvulag genes never blended completely. From time to time during the history of these people the old rivalries would be resurrected.”

“And crushed by the high-tech majority,” Claude said. “Until this one group of barbarian throwbacks found a perfect refuge instead of coming to the usual quixotic end.”

She nodded her agreement “It was perfect for the exiles, our Pliocene Earth… except for the irony that equally quixotic humans should also have desired to dwell on it.”

She pointed to a pneumatic barge far out on the river. “There goes one of the products of the human advent. Before the humans came, the Tanu had simple rafts of wood. They had little river commerce because of their dislike of water. They supervised their own plantations and even did honest work because there were not so many rama slaves. The torcs for the little apes formerly had to be made by hand in the same manner as their own golden torcs.”

“Do you mean that human know-how enabled mass production?”

“For the ape torcs, yes. And the entire silver and gray system, with its linkage to the golden torcs of the Tanu rulers, was devised by a human psychobiologist. They made him a demigod and he still lives in Muriah, Sebi-Gomnol the Lord Coercer. But I remember the pinched little self-hating man who came to my auberge forty years ago. Then he was called Eusebio Gomez-Nolan.”

“So a human being is responsible for this slave setup? Sweet Lord. Why do we screw things up, wherever we go?”

She gave a short bitter laugh. With her hair straggling in sweat curls about her ears and forehead, she seemed to be scarcely forty-five years old. “Gomnol is not the only traitor to our race. There was a Turkish man of the circus, one of my earliest clients, named Iskender Karabekir. His fondest wish, as he told me, was to train sabertooth tigers to do his bidding. But I have discovered that in this Exile world he devoted himself instead to the domestication of chatikot and heuadotberia and amphicyons, which became pivotal in the subsequent Tanu domination of society. The ancient Hunt and Grand Combat were fought by Tanu and Firvulag afoot. The groups were evenly matched, for what the Firvulag lacked in finesse and sophisticated metafunctions they made up in sheer numbers and a more rugged physique. But a mounted Tanu Hunt was a different matter. And a Grand Combat with Tanu and torced human warriors on chalikoback and Firvulag afoot has become an annual massacre.”

Claude stroked his chin. “Still, there was the Battle of Agincourt, if you’ll pardon my mentioning it.”

“Bof!” said Angélique Guderian. “Longbows will not conquer the Tanu, nor will gunpowder. Not while perverse member of our own human race betray their fellows! Who taught the Tanu physicians how to reverse the human sterilizations? A gynecologist from the planet Astrakhan. A human woman! Not only our talents but our very genes have been placed in the service of these exotics, and many, such as Martha, choose death rather than the degradation of becoming brood stock. Do you know how Martha came to us?”

Claude shook his head.

“She threw herself into the Rhine, hoping to drown herself in the spring flood rather than submit to a fifth impregnation. But she was cast ashore, Dieu merci, and Steffi found her and restored her. There are many others like Martha among us. Knowing them, loving them, and knowing also that I am the one ultimately responsible for their pain, you will understand why I cannot rest until the power of the Tanu is broken.”

The river was turning from shining pewter to gold. On the Black Forest side, the heights of the Feldberg to the south became luminous with the sinking sun, tinted primrose and purple. In order to reach Sugoll, they would have to go up into that high country and cross at least seventy kilometers of mountain forest, and all this before even beginning their search for the Danube.

“Quixotic,” Claude said. He was smiling.

“Are you sorry you agreed to help me? You are an enigma to me, Claude. I can understand Felice, Richard, Martha, the strong-willed ones of our company such ^M Chief Burke. But I have not yet been able to understand you. I cannot see why you came to the Pliocene at all, much less why you agreed to go on this quest for the Ship’s Grave. You are too sensible, too self-posssessed, too, debonaire!”

He laughed. “You have to understand the Polish character, Angélique. It breeds true, even in a Polish-American like me. We were speaking of battles. Do you know which one we Polacks are proudest of? It happened at the beginning of the Second World War. Hitler’s Panzer tanks were rolling into the northern part of Poland and there was no modern weaponry to stop them. So the Pomeranian Cavalry Brigade charged the tanks on horseback, and they were wiped out, man and beast. It was madness, but it was glorious… and very, very Polish. And now suppose you tell me why you decided to come to the Pliocene.”

“It was not because of romanticism,” she said. There was no more of the accustomed asperity in her tone, not even grief. She told her story flatly, as though it were the scenario of a stage play that she had been forced to attend too many times, or even an act of confession.

“In the beginning, when I was only greedy for money, I did not care what kind of world lay on the other side of the time-portal. But later, when my heart was finally touched, it became very different. I attempted to have the travelers send messages back to me, reassuring me about the nature of the Pliocene land. Time and again I gave to sensible-seeming persons materials that I felt certain would survive the reversal of the temporal field. Very early tests by my late husband had shown that amber was best, and so my envelopes were pieces of this material, carefully sliced in half, with little wafers of ceramic to insert. These could be written upon with an ordinary graphite pencil, then sealed in the amber with natural balsam cement. I instructed certain travelers to study the ancient scene, write down their considered judgment of it, then return to the vicinity of the time-gate where the translations invariably took place at dawn. You see, Professor Guderian had long ago established that solar time in the ancient epoch was the same as that of the modern world we lived in. I had wished to give the new arrivals maximum daylight to adjust to the new environment, so I always sent them at sunup. Malheureusement, this unvarying program made it most convenient for the minions of the Tanu to control the portal! Long before it occurred to me to try the amber message holders, the exotics had built Castle Gateway and taken steps to seize all time-travelers immediately upon their arrival.”

“So you never got any messages from the past?”

“Nothing. In later years, we tried more sophisticated techniques for mechanical retrieval of information, but nothing worked. We could get no pictures, no sounds from the Pliocene. The devices always returned to us in a useless condition. Of course, it is easy to see why!”
