Ahead, the wall at the southeastern edge of the city was drawing closer. It was high and thick and eroded to rubble at the top. It also appeared to be lined with skeletons—thousands upon thousands of dead Luddites. The notch toward which Blaine was slowly moving appeared to be at least two hundred feet deep, and here the trestle which bore the track was very dark, as if someone had tried to burn it or blow it up.
“What happens if we come to a place where the track is gone?” Eddie asked. He realized he kept raising his voice to talk to Blaine, as if he were speaking to somebody on the telephone and had a bad connection. “AT EIGHT HUNDRED MILES AN HOUR?” Blaine sounded amused. “SEE YOU LATER, ALLIGATOR, AFTER A WHILE, CROC-ODILE, DONT FORGET TO WRITE.” “Come on!” Eddie said. “Don’t tell me a machine as sophisticated as you can’t monitor your own trackage for breaks.”
“WELL, I COULD HAVE,” Blaine agreed, “BUT—AW, SHUCKS!— I BLEW THOSE CIRCUITS OUT WHEN WE STARTED TO MOVE.”
Eddie’s face was a picture of astonishment. “Why?” “IT’S QUITE A BIT MORE EXCITING THIS WAY, DON’T YOU THINK?” Eddie, Susannah, and Jake exchanged thunderstruck looks. Roland, apparently not surprised at all, sat placidly in his chair with his hands folded in his lap, looking down as they passed thirty feet above the wretched hovels and demolished buildings which infested this side of the city. “LOOK CLOSELY AS WE LEAVE THE CITY, AND MARK WHAT YOU SEE,” Blaine told them. “MARK IT VERY WELL.”
The invisible Barony Coach bore them toward the notch in the wall. They passed through, and as they came out the other side, Eddie and Susannah screamed in unison. Jake took one look and clapped his hands over his eyes. Oy began to bark wildly.
Roland stared down, eyes wide, lips set in a bloodless line like a scar. Understanding filled him like bright white light. Beyond the Great Wall of Lud, the real waste lands began.
THE MONO HAD BEEN descending as they approached the notch in the wall, putting them not more than thirty feet above the ground. That made the shock greater … for when they emerged on the other side, they were skimming along at a horrifying height—eight hundred feet, perhaps a thousand.
Roland looked back over his shoulder at the wall, which was now receding behind them. It had seemed very high as they approached it, but from this perspective it seemed puny indeed—a splintered fingernail of stone clinging to the edge of a vast, sterile headland. Granite cliffs, wet with rain, plunged into what seemed at first glance to be an endless abyss. Directly below the wall, the rock was lined with large circular holes like empty eyesockets. Black water and tendrils of purple mist emerged from these in brackish, sludgy streams and spread downward over the granite in stinking, overlapping fans that looked almost as old as the rock itself. That must be where all the city’s waste-product goes, the gunslinger thought. Over the edge and into the pit. Except it wasn’t a pit; it was a sunken plain. It was as if the land beyond the city had lain on top of a titanic, flat-roofed elevator, and at some point in the dim, unrecorded past the elevator had gone down, taking a huge chunk of the world with it. Blaine’s single track, centered on its narrow trestle, soaring above this fallen land and below the rain-swollen clouds, seemed to float in empty space.
“What’s holding us up?” Susannah cried.
“THE BEAM, OF COURSE,” Blaine replied. “ALL THINGS SERVE IT, YOU KNOW. LOOK DOWN—I WILL APPLY 4X MAGNI-FICATION TO THE LOWER QUADRANT SCREENS.” Even Roland felt vertigo twist his gut as the land beneath them seemed to swell upward toward the place where they were floating. The picture which appeared was ugly beyond his past knowledge of ugliness . . . and that knowledge, sadly, was wide indeed. The lands below had been fused and blasted by some terrible event—the disastrous cataclysm which had driven this part of the world deep into itself in the first place, no doubt. The surface of the earth had become distorted black glass, humped upward into spalls and twists which could not properly be called hills and twisted downward into deep cracks and folds which could not properly be called valleys. A few stunted nightmare trees flailed twisted branches at the sky; under magnification, they seemed to clutch at the travellers like the arms of lunatics. Here and there clusters of thick ceramic pipes jutted through the glassy surface of the ground. Some seemed dead or dormant, but within others they could see gleams of eldritch blue-green light, as if titanic forges and furnaces ran on and on in the bowels of the earth. Misshapen flying things which looked like pterodactyls cruised between these pipes on leathery wings, occasionally snapping at each other with their hooked beaks. Whole flocks of these gruesome aviators roosted on the circular tops of other stacks, apparently warming themselves in the updrafts of the eternal fires beneath.
They passed above a fissure zig-zagging along a north-south course like a dead river bed . . . except it wasn’t dead. Deep inside lay a thin thread of deepest scarlet, pulsing like a heartbeat. Other, smaller fissures branched out from this, and Susannah, who had read her Tolkien, thought: This is what Frodo and Sam saw when they reached the heart of Mordor. These are the Cracks of Doom. A fiery fountain erupted directly below them, spewing flaming rocks and stringy clots of lava upward. For a moment it seemed they would be engulfed in flames. Jake shrieked and pulled his feet up on his chair, clutching Oy to his chest. “DON’T WORRY, LITTLE TRAILHAND,” John Wayne drawled. “REMEMBER THAT YOU’RE SEEING IT UNDER MAG-NIFICATION.”
The flare died. The rocks, many as big as factories, fell back in a soundless storm.
