The Long War

stepwise Americas, became accustomed to stopping work at twilight, when the big loading bay doors were flung open, and the trolls joined in the harmonies and undertones of the long call as it echoed across the reaches of world after world.
    ‘I mean,’ Maggie said to Mac and Nathan, ‘in Star Trek they put a Klingon on the bridge.’
    ‘And a Borg,’ said Nathan.
    ‘Well, there you go.’
    ‘Not a Romulan, though,’ Mac said. ‘Never a Romulan.’
    ‘The trolls are staying,’ Maggie said firmly.

    I T TOOK N ELSON Azikiwe a couple of months after that talk with Ken, when he’d let the cat out of the bag about his resignation, for him to tidy up his affairs in the parish, dispose of extraneous belongings, and brief his successor – including on the temperamental toilet – before he was ready to depart on the next phase of his life, in search of the Lobsang Project and other mysteries. He took his time. He had always led something of an itinerant life, but believed in making time to say his goodbyes properly.
    He decided to travel to America by plane; his generation wasn’t used to the slow-boat nature of twain travel. But there weren’t as many aeroplanes around these days, Nelson discovered, not since the Long Earth had begun to be serviced by the twains. It was the new worlds, of course, for which the twains were so well suited: airships didn’t need airports, they could set you down easily almost anywhere. But even for lateral, cross-Earth travel, even on the Datum, airships had come back into vogue. For one thing helium, a safely non-flammable lift gas, was a whole lot easier to obtain now, the Datum’s natural stock having been badly depleted before the resources of the stepwise worlds had been opened up. And the stately pace of airships certainly worked for cargo: sacks of corn and mineral ore didn’t mind how long it took to get there, and rarely complained about the in-flight movie.
    But an industry like the traditional airlines would take some time to die, and for now, on the Datum, the planes still flew – even though for this trip Nelson had to put up with delays, as many US flights were grounded because of ash clouds arising from an event at Yellowstone, some kind of minor eruption there.
    The plane Nelson finally caught swung out from England, crossed the north Atlantic, flew down over the Canadian Shield, and at last reached the endless farmland of Datum America, which spread beneath his window like a glowing carpet. If you had the eye for it, he realized, there were occasional gaps to be seen in that grand panorama of cultivation, scraps of recovering wildness in the summer green where a homestead or a farm had been abandoned, almost certainly because the owners had decided to step Westward. (And it was West for most Americans, despite the assurances of the experts that the stepping labels ‘West’ and ‘East’ were purely arbitrary.) Off they stepped, in search of more land, a better life. Or, he mused, possibly they went simply because, well, the new worlds were out there , and there was something in the genes of an American, and perhaps even a Canadian, that impelled you always to move on. It was a frontier with apparently no end, and while there wasn’t exactly a stepwise stampede these days the Long Earth still drew in the pioneers.
    His own destination was more modest: O’Hare. He’d stop in Chicago a while. Then he had plans to visit a new university being built in Madison, Wisconsin, West 5, as part of the city’s post-nuke recovery. He had friends there, and interests. Madison was where Willis Linsay had first posted the plans for a prototype Stepper box on the internet, a glorious, destructive gesture that had changed the world for ever – indeed, the worlds. And Madison had been the boyhood home of Joshua Valienté himself. Nelson, on the track of the Lobsang Project, had an inkling that Madison was a place where he might find some things out, get some questions answered.
    As it turned out, this tentative plan didn’t even survive his leaving the airport.
    Nelson was always glad to get out of the cramped enclosure of a plane. He was a large man, the kind of man who had trouble fitting into an airline seat, but who could walk through any neighbourhood anywhere without having to worry overmuch about his security. Sometimes the deference accorded to him simply because of his size bothered him. But by and large, he reflected as he patiently queued his way through
