The train continues, into the stain, into the cacotopic zone that has beaten New Crobuzon back.

Judah walks for months. His life becomes a fugue of walking. Over creeks, quagmire, over rockland, through forests of vitreous trees, through forests that he thinks are fossil trees then sees are great skeletons. He walks a bonescape, an ossein ecology with its own undergrowth and scavengers.

He passes lakes that bubble with the fighting of vodyanoi tribes. He sees chimneys extruded from mountainsides where there are troglodyte villages. Judah is the guest of neglected priest-tribes. He is robbed by fReemade. He joins a fReemade band.

His body becomes a traveller’s body again. The startling muscles of his arms and chest subside and he is once again a thin mannequin tempered by travel. Garuda come to feed him, dropping from the sky with wordless charity. He checks his just-adequate maps, his compass. He does not retrace his steps the long route he has gone but goes directly east.

Judah passes through a storm, in a basalt place hundreds of miles from New Crobuzon, by blitzbaums, miles-high lightning trees. Bolts held still by cryptic forces, forking into boughs, a magnesium-bright forest.

The low rust skyline of a time-eaten iron town. And a swamp of thaumaturgically jinxed mud that degenerates his boots into worms. And a barrow and a buried church, and fields of wild berries, and beautiful hills. Five times he fights animals and three times he fights sentients. Judah runs or kills.

He is a quieter man. He moves with effortless expertise. It has been many weeks since he made a grass golem to walk with him, for him to talk to until the wind picks it apart. Judah passes cattle that were once domestic and are now feral. The ruins of fences, deserted pastures, miles by miles.

And then at last Judah comes down from the sudden hills and stands quiet like an idiot. At last he comes forward and now he stumbles. Judah goes to his knees. It is cold. What seasons have passed? Judah crawls forward and touches the rails.

It seems impossible that he can touch this metal, these iron sashes that wind around the weather and geography, that for all the blood and salt he spilled on them, the bones of all the men and women they press upon, are nothing, are a nothing, are made nothing by time and dust.

They are scavenged. Imperfect. Sections are gone. The tracks look out from the dirt and hide again. It has been a time since any train came this way.

Judah looks north along the cut. He remembers the carving of the roadbed. He is a long way north of the swamp.
