‘A cartographer’s nightmare.’ Tomm laughed.
‘And why are there no windows or doors?’
‘We can make windows,’ he said. ‘We can hang doors.’ He took her hands. ‘Questions, questions, Enna! You’re worse than all these grumpy old Philosophers. This is your discovery. Relish the moment!’
There was a deep harrumph. Bayle, Enna’s father, came walking towards them, trailed by acolytes, lesser men but Philosophers themselves. Tomm hastily released Enna’s hands.
‘But Enna is right,’ Bayle said. ‘There is some familiarity about the place, and yet perhaps that merely blinds us to how much is strange . . .’
Bayle wore his dress uniform, topped off by his cap of spindling fur and feathers. Though he had devoted the last three decades of his life to science, Bayle had retained an honorary rank in the army of New Foro, and ‘for the sake of general morale’, as he put it, he donned his uniform to mark moments of particular significance during their long journey. But Enna knew that no matter how extravagant his appearance, her father’s mind was sharper than any of those around him.
He tapped the walls of the nearest building with his stick. ‘Certainly the layout follows no obvious rational design, as does the centre of New Foro, say. But there are patterns here.’ He walked them briskly through the narrow alleys between the buildings. ‘Can you see how the largest buildings are clustered on the outside, and the smaller huts are in their shade?’
‘It almost looks organic,’ Enna said impulsively. ‘Like a forest, dominated by its tallest trees.’
Bayle eyed her appreciatively. ‘I was going to compare it to a bank of salt crystals.’ Salt had become something of an obsession of Bayle’s during their journey. There was salt everywhere in the Lowlands; there were even plains covered with the stuff, the relics of dried-up lakes. Bayle was gathering evidence for his contention that the Lowland had once been the bed of a mighty body of water. ‘But I admit, daughter, that your analogy may be more apt. This city is not planned as we think of it. It is almost as if it has grown here.’
Tomm seemed confused. ‘But that’s just an analogy. I mean, this is a city, built by human hands – though maybe long ago. That much is obvious, isn’t it?’
Bayle snapped, ‘If everything were obvious we would not have needed to come out here to study it.’ He gave Enna a look that spoke volumes. The boy has a pretty face but a shallow mind, said that withering expression. You can do better.
But Tomm was Enna’s choice, and she returned his glare defiantly.
They were interrupted by a raucous hail. ‘Sir, sir! Look what I’ve found!’ It was Momo. The burly, one-eyed pilot came stumbling around the corner of a building.
And walking with him was a woman. Dressed in some kind of scraped animal skin, she was tall, aged perhaps fifty, in her way elegant despite her ragged costume. She eyed the Philosophers, detached. In that first moment Enna thought she seemed as cold, strange and hard-edged as her city.
Bayle stepped forward, his gloved hand extended. ‘Madam,’ he said, ‘if you can understand me, we have a great deal to discuss.’ The woman took Bayle’s hand and shook it. The subordinate Philosophers applauded enthusiastically.
It was yet another remarkable moment in this unprecedented trek of discovery. This was Bayle’s first contact with any of the ‘lost souls’ believed to inhabit the Lowland, stranded here from ages past; to find such people and ‘rehabilitate’ them had been one of his stated goals from the beginning.
But Enna caught a strange whiff about the woman, an iron stink that at first she couldn’t place. It was only later that she realised it was the smell of raw meat – of blood.
As night fell, the explorers and their attendants and servants dispersed gladly into the city’s bare buildings. After the dirt of the plain, it was going to be a relief to spend a night within solid walls.
Bayle himself established his base in one of the grander buildings on the edge of the city, bathed in light even at the end of the day. It seemed he planned to spend most of the night in conversation with the woman who was, as far as anybody could tell, the city’s sole inhabitant; he said they had much to learn from each other. He kissed his daughter goodnight, trusting her safety to his companions, and to her own common sense.
So it was a betrayal of him, of a sort, when in the darkest night Enna sought out Tomm’s warm arms. It wasn’t hard for her to put her guilt aside; at twenty she had a healthy awareness of how far her father’s opinions should govern her life.
But she dreamed. She dreamed that the building itself gathered her up and lifted her into the sky, just as she was cradled by Tomm’s arms – and she thought she smelled that iron tang again, the scent of blood.
The dream became disturbing, a dream of confinement.
Bayle had formulated many objectives for his Expedition.
Always visible from Foro, Puul and the other towns of the Shelf, the Lowland, stretching away below in redshifted ambiguity, had been a mystery throughout history. Now that mystery would be dispelled. Cartographers would map the Lowland. Historians, anthropologists and moralists hoped to make contact with the lost people of the Lowland plains, if any survived. Clerics, mystics, doctors and other Philosophers hoped to learn something about Effigies, those spectral apparitions that rose from dying human bodies, or some of them, and fled to the redshifted mysteries of the Lowland. Perhaps some insight would be gained into the cause of the Formidable Caresses, the tremendous rattlings that regularly shook human civilisation to pieces. There were even a few soldiers and armourers, hoping to track down Weapons, ancient technology gone wild, too wily to have been captured so far.
There had already been many successes. Take the light storms, for instance.
Old Earth’s blueshifted sky was a dome of stars that spun around the world. Day and night, and the seasons of the year, were governed not by the sky but by the flickering uncertainties of the light that emanated from the Lowland. Now Bayle’s physicists had discovered that these waves of light pulsed at many frequencies, ‘like the harmonics of a plucked string,’ as one mathematician had described it. Not only that, because of the redshifting of the light that struggled up to higher altitudes, the harmonic peaks that governed the daily cycles here were different from those to be observed from Foro, up on the Shelf, where time ran faster.
Enna was walked through the logic by her father. The effects of time stratification, redshifting and light cycling subtly intermeshed, so that whether you were up on the Shelf or down in the Lowland the length of day and night you perceived was roughly similar. This surely couldn’t be a coincidence. As Bayle said, ‘It adds up to a remarkable mathematical argument for the whole world having been designed to be habitable by people and their creatures.’
That, of course, had provoked a lively debate.
Forons were traditionally Mechanists, adhering to a strand of natural philosophy that held that there was no governing mind behind the world, that everything about it had emerged from the blind working-out of natural laws – like the growth of a salt crystal, say, rather than the purposeful construction of a machine. However, there were hard-line Creationists who argued that everything on Old Earth required a purposeful explanation.
After centuries of debate a certain compromise view had emerged, it seemed to Enna, a melding of extreme viewpoints based on the evidence. Even the most ardent Mechanists had been forced to accept that the world contained overwhelming evidence that it had been manufactured, or at least heavily engineered. But if Old Earth was a machine, it was a very old machine, and in the ages since its formation, natural processes of the kind argued for by the Mechanists had surely operated to modify the world. Old Earth was a machine that had evolved.
