“Perhaps we should turn after all,” Qilian said, or started to say. But by then, the three ships had loosed their missiles: four apiece, grouping into two packs of six, one for the Mandate of Heavenand one for us.
Muhunnad needed no further encouragement. He whipped us around with all haste, pushing the River Volga’sthrust to its maximum. Again, the stress of it was enough to set the ship protesting. At the same time, Muhunnad brought our own weapons into use, running those guns out on their magnetic cradles and firing at the missiles as they closed distance between us and the Christians. Given the range and efficacy of our beam weapons, it would not have troubled him to eliminate the three ships. In concentrating on the missiles, not the pursuers, he was doing all that he could not to inflame matters further. As an envoy of Greater Mongolia, I suppose I should have been grateful. But I was already beginning to doubt that the fate of my empire was going to be of much concern for me.
Because we had turned around, the Mandate of Heavenwas the first to reach the portal. By then, the door had begun to close, but it only took a brief assault from the Mandate’schaser guns to snip a hole in it. Muhunnad had destroyed nine of the twelve missiles by this point, but the remaining three were proving more elusive; in witnessing the deaths of their brethren, they appeared to have grown more cunning. By the time the Mandatecleared the portal, the three had arrived within fifteen liof the River Volga.By switching to a different fire pattern, Muhunnad succeeded in destroying two of them, but the last one managed to evade him until it had come within five li.At that point, bound by the outcome of some ruthless logical decision-making algorithm, the missile opted to detonate rather than risk coming any closer. It must have hoped to inflict fatal damage on us, even at five li.
It very nearly did. I recalled what our pilot had said about there being no such thing as a harmless interstellar culture. The blast inflicted severe damage to our rear shielding and drive assembly, knocking off another two stabilization vanes.
And then we were through, back into the Infrastructure. We had survived our first encounter with another galactic empire.
More were to follow.
In my mind’s eye, I have an image of a solitary tree, bare of leaves, so that its branching structure is laid open for inspection. The point where each branch diverges from a larger limb is a moment of historical crisis, where the course of world events is poised to swerve onto one of two tracks.
Before his death, our founder spoke of having brought a single law to the six directions of space, words that have a deep resonance for all Mongols, as if it was our birthright to command the fundamental fabric of reality itself. They were prescient words, too, for the bringing of unity to Greater Mongolia, let alone the first faltering steps toward the Expansion, had barely begun. Fifty-four years after his burial, our fleet conquered the islands of Japan, extending the empire as far east as it was possible to go. But the day after our fleet landed, a terrible storm battered the harbors of those islands, one that would surely have repelled or destroyed our invasion fleet had it still been at sea. At the time, it was considered a great good fortune; a sure sign that Heaven had ordained this invasion by delaying that storm. Yet who is to say what would have become of Japan, had it not fallen under Mongol authority? By the same token, who is to say what would have become of our empire if its confident expansion had been checked by the loss of that fleet? We might not have taken Vienna and the cities of western Europe, and then the great continents on the other side of the ocean.
I thought of Muhunnad’s Shining Caliphate. The common view is that the Islamists were monotheistic savages until swept under the tide of the Mongol enlightenment. But I am mindful that history is always written by the victors. We regard our founder as a man of wisdom and learning first and a warrior second, a man who was respectful of literacy, was curious about the sciences, and possessed a keen thirst for philosophical inquiry. Might the conquered have viewed him differently, I wonder? Especially if our empire fell, and we were not there to gilden his name?
No matter; all that need concern us is that solitary tree, that multiplicity of branches, reaching ever upward. After the moment of crisis, the point of bifurcation, there should be no further contact between one branch and the next. In one branch, the Mongols take the world. In another, the Islamists. In another, some obscure sect of Christians. In another, much older branch, none of these empires ever become a gleam in history’s eye. In an even older one, the lemurs are masters of Creation, not some hairless monkey.
But what matters is that all these empires eventually find the Infrastructure. In some way that I cannot quite grasp, and perhaps will never truly understand, the khorkoimachinery exists across all those branches. Not simply as multiple copies of the same Infrastructure, but as a single entity that in some way permits the reunification of those branches: as if, having grown apart, they begin to knot back together again.
I do not think this is intentional. If it were, the leaky nature of the Infrastructure would have been apparent to us five hundred years ago. It seems more likely to me that it is growing leaky; that some kind of insulation is beginning to wear away, an insulation that prevents history short-circuiting itself, as it were.
But perhaps I am wrong to second-guess the motives of aliens whose minds we will never know.
Perhaps all of this is unfolding according to some inscrutable and deliriously protracted scheme of our unwitting wormlike benefactors. I do not think we will ever know.
I shall spare you the details of all the encounters that followed, as we slipped from one point of weakness to another, always hoping that the next transition would be the one that brought us back to Mongol space, or at least into an empire we could do business with. By the time of our eighth or ninth transition, I think, Qilian would have been quite overjoyed to find himself a guest of the Shining Caliphate. I think he would have even settled for a humbling return to the Christians: by the time we had scuttled away from empires as strange, or as brazenly hostile, as those of the Fish People or the Thin Men, the Christians had come to seem like very approachable fellows indeed.
But it was not to be. And when we dared to imagine that we had seen the worst that the branching tree of historical possibilities could offer, that we had done well not to stray into the dominion of the lemurs, that Heaven must yet be ordaining our adventure, we had the glorious misfortune to fall into the realm of the Smiling Ones.
They came hard and fast, and did not trifle with negotiation. Their clawlike green ships moved without thrust, cutting through space as if space itself was a kind of fluid they could swim against. Their beam weapons etched glimmering lines of violet across the void, despite the fact that they were being deployed in hard vacuum. They cut into us like scythes. I knew then that they could have killed us in a flash, but that they preferred to wound, to maim, to toy.
The River Volgatwisted like an animal in agony, and then there was a gap in my thoughts wide enough for a lifetime.
The first thing that flashed through my mind after I returned to consciousness was frank amazement that we were still alive; that the ship had not burst open like a ripe fruit and spilled us all into vacuum. The second thing was that, given the proximity of the attacking vehicles, our stay of execution was unlikely to be long. I did not need the evidence of readouts to tell me that the
