Sometimes Lin would sit in one of Kinken’s tiny parks. She would be still among the slowly blossoming trees and watch her kind, all around her. She would stare high above the park, at the backs and sides of tall buildings. One time, she saw a young human girl lean out from a window high above, that was stuck almost at random at the top of a stained concrete wall at the back of the building. Lin saw the girl watching her khepri neighbours placidly, as her family’s washing fluttered and snapped in the brisk wind from a pole jutting beside her. A strange way of growing up, thought Lin, imagining the child surrounded by silent, insect-headed creatures, as strange as if Lin had been brought up among vodyanoi but that thought led her uncomfortably in the direction of her own childhood.

Of course, her journey to these despised streets was a walk back through the city of her memory. She knew that. She was steeling herself to think back.

Kinken had been Lin’s first refuge. In this strange time of isolation, when she cheered the efforts of khepri crime-queens and walked as an outcast in all the quadrants of the city-except, perhaps, Salacus Fields, where outcasts ruled-she realized that her feelings for Kinken were more ambivalent than she had so far allowed.

There had been khepri in New Crobuzon for nearly seven hundred years, since the Fervent Mantis crossed the Swollen Ocean and reached Bered Kai Nev, the eastern continent, the khepri home. A few merchants and travellers had returned on a one-way mission of edification. For centuries, the stock of this tiny group sustained itself in the city, became natives. There had been no separate neighbourhoods, no home-grubs, no ghettos. There were not enough khepri. Not until the Tragic Crossing.

It was a hundred years since the first refugee ships had crawled, barely afloat, into Iron Bay. Their enormous clockwork motors were rusted and broken, their sails ragged. They were charnel ships, packed with Bered Kai Nev khepri who were only just alive. Contagion was so merciless that ancient taboos against water-burial had been overthrown. So there were few corpses on board, but there were thousands of dying. The ships were like crowded antechambers to morgues.

The nature of the tragedy was a mystery to the New Crobuzon authorities, who had no consuls and little contact with any of the countries of Bered Kai Nev. The refugees would not speak of it, or if they did they were elliptical, or if they were graphic and explicit the language barrier blocked understanding. All that the humans knew was that something terrible had happened to the khepri of the eastern continent, some horrendous vortex that had sucked up millions, leaving only a tiny handful able to flee. The khepri had christened this nebulous apocalypse the Ravening.

There were twenty-five years between the arrival of the first ships and the last. Some slow, motorless vessels were said to be crewed entirely by khepri born at sea, all the original refugees having died during the interminable crossing. Their daughters did not know what it was they fled, only that their dying broodmas had all bade them go west, and never to turn the wheel. Stories of the khepri Mercy Ships-named for what they begged-reached New Crobuzon from other countries on the eastern coast of the Rohagi continent, from Gnurr Kett and the Jheshull Islands, from as far south as the Shards. The khepri diaspora had been chaotic and diverse and panicked.

In some lands the refugees were butchered in terrible pogroms. In others, like New Crobuzon, they were welcomed with unease, but not with official violence. They had settled, become workers and tax-payers and criminals, and found themselves, by an organic pressure just too gentle to be obvious, living in ghettos; preyed on, sometimes, by bigots and thugs.

Lin had not grown up in Kinken. She was born in the younger, poorer khepri ghetto of Creekside, a grubby stain in the northwest of the city. It was nearly impossible to understand the true history of Kinken and Creekside, because of the systematic mental erasure that the settlers had undertaken. The trauma of the Ravening was such that the first generation of refugees had deliberately forgotten ten thousand years of khepri history, announcing their arrival at New Crobuzon to be the beginning of a new cycle of years, the City Cycle. When the next generation had demanded their story from their broodmas, many had refused and many could not remember. Khepri history was obscured by the massive shadow of genocide.

So it was hard for Lin to penetrate the secrets of those first twenty years of the City Cycle. Kinken and Creekside were presented as fait accompli to her, and to her broodma, and the generation before that, and the generation before that.

Creekside had no Plaza of Statues. It had been a tumbledown slum for humans a hundred years ago, a rookery of found architecture, and the khepri home-grubs had done little more than encase the ruined houses with cement, petrifying them forever on the point of collapse. The denizens of Creekside were not artists or fruitbar owners, moiety chiefs or hive elders or shopkeepers. They were disreputable and hungry. They worked in the factories and in the sewers, sold themselves to whomever would buy. Their sisters in Kinken despised them.

In Creekside’s decrepit streets, strange and dangerous ideas blossomed. Small groups of radicals met in hidden halls. Messianic cults promised deliverance to the chosen.

Many of the original refugees had turned their backs on the gods of Bered Kai Nev, angry that they had not protected their disciples from the Ravening. But subsequent generations, not knowing the nature of the tragedy, offered their worship again. Over a hundred years, pantheon temples had been consecrated in old workshops and deserted dancehalls. But many Creeksiders, in their confusion and hunger, turned to dissident gods.

All the usual temples could be found in Creekside’s confines. Awesome Broodma was worshipped, and the Artspitter. Kindly Nurse presided over the shabby hospital, and the Tough Sisters defended the faithful. But in rude shacks that mouldered by the industrial canals, and in front rooms blocked by dark windows, prayers were raised to stranger gods. Priestesses dedicated themselves to the service of the Elyctric Devil or the Air Harvester. Furtive groups clambered to their roofs and sang hymns to the Wingsister, praying for flight. And some lonely, desperate souls-like Lin’s broodma-pledged their fealty to Insect Aspect.

Properly transliterated from Khepri into the New Crobuzon script, the chymico-audio-visual composite of description, devotion and awe that was the name of the god was rendered Insect/Aspect/ (male)/(singleminded). But the few humans that knew of him called him Insect Aspect, and that was how Lin had signed him to Isaac when she told him the story of her upbringing.

Since the age of six, when she had torn the chrysalis from what had been her baby headlarva and was suddenly a headscarab, when she had burst into consciousness with language and thought, her mother had taught her that she was fallen. The gloomy doctrine of Insect Aspect was that khepri women were cursed. Some vile flaw on the part of the first woman had consigned her daughters to lives encumbered with ridiculous, slow, floundering bipedal bodies and minds that teemed with the useless byways and intricacies of consciousness. Woman had lost the insectile purity of God and male.

Lin’s broodma (who scorned a name as a decadent affectation) taught Lin and her broodsister that Insect Aspect was the lord of all creation, the all-powerful force that knew only hunger and thirst and rutting and satisfaction. He had shat out the universe after eating the void, in a mindless act of cosmic creation the purer and more brilliant for being devoid of motive or awareness. Lin and her broodsister were taught to worship Him with a terrified fervour, and to despise their self-awareness and their soft, chitinless bodies.
