The city was born of salt and silence. The salt garden, stretched on the cracked bottom of the former Milky Sea, creaked underfoot like an old instrument; the wind carried particles of salt that settled on the eyelashes and the tongue, leaving a metallic aftertaste of former storms. The townhouses had balconies covered with white tarnish, and the streets, covered in a brittle crust, seemed to glow at night as if a faint, bluish life was smouldering in them. A beacon towered over the town, connected to a clock that stopped ticking whenever someone within a hundred paces lied. Lira had come to Sólogród from the north, where water was still moving and words less fragile. She was a cartographer, or rather - still - an apprentice. From Master Radwan she was given what he claimed was the most ordinary map: a sheet of thin parchment, slightly harder at the edges, bound with bindings that smelled of ancient smoke. Except that this map was breathing. When Lira placed her hand on it, lines moved under her fingertips, as if tiny fish were running under the skin. Sometimes the drawing of the city expanded and contracted - to the rhythm of her own breathing. - 'Don't just draw what is,' Radwan used to say when he was still alive and sipping bitter brine tea. - Draw what will be. Don't waste parchment on the present, it is the least movable of all times. On that night, the Salt Garden donned the light. It was the Night of Descent - once every few decades the sky would bend over the bottom so much that the stars seemed to peek through the cracks, and some fell. Not like stones. Like thoughts that someone lets out quietly and tries to catch before they escape. Simon, a young glassblower with hands burned by thousands of tiny fires, carried a lantern made of salt glass. He had carved it himself - a hexagonal panel with thin ribs through which the flame passed in blues and purples, as if the colour was not the hue but the temperature of the story. He knew Lyra enough to know that maps can draw her in more than people. Nevertheless, he walked beside her, silent, like a man accustomed to working with material that disintegrates from breathing too loudly. - 'The Night of Descent will make your map dance,' he said, adjusting the lantern strap on his shoulder. - 'They say it sometimes shows passages that aren't there during the day. Lira smiled, not taking her eyes off the parchment. The paths on the map dampened, as if freshly drawn, and spread from the surveyor's lantern towards the edges of the city. One line trembled at the edge of the parchment, as if it couldn't decide whether it wanted to extend. As the clock went off for a moment over Sólogrod, and brittle, whitish sparks sprinkled from the dark sky, the line leapt forward and tore a corner of the map. Lira twitched - and then she heard a sound. Salt was singing. At first in a single, distant tone, then whole streets joined in like choirs in a closed cathedral. The clock started again, stretching the silence into thin filaments, and at the northern edge of the city, where the bottom fell into an old basin, something so bright that the lanterns went out with envy flashed. A splinter of sky. Lira knew it even before Simon uttered the word they both expected. - 'It fell into the Basilica on the Bottom,' he stated quietly. - You know what it means. She knew. The Basilica on the Bottom, carved into the salt when the sea was just receding, was a place the inhabitants spoke of in whispers, not because they were afraid, but because they did not want to wake what slept there. For many years the door had been closed. Supposedly, they only opened on two occasions: when the Milky Sea rolled to the other side in its sleep, or when a piece of sky hit the exact centre of the nave. Lira grabbed a corner of the map. The parchment pulsed. Lines expanded, entered each other, unravelled like hair. At the very bottom, beneath the layers of streets, she noticed a thin line that had not been there before - it wriggled like a pale eel, leading straight to the signature of the Basilica, drawn by her Master's fine hand. Next to it was Radwan's mark: a star with a short crack in it, as if someone had tried to fold it and it refused to return to its previous shape. - 'Let's go,' she said, before her heart had time to turn her around. - Before the footsteps faded away. They were going down. First through a water supply tunnel from a time when water still had somewhere to go, then through salt warehouses where the walls were sprinkled with beads like thick snow. Simon shone a lantern, and the colour of the flame changed around every bend, as if the corridors were tuned to a non-existent scale. Lira stared at the map, careful not to let the sweat from her palms drip onto the parchment. The line continued to lead them, sometimes splitting into two or three, then converging into one again. As they passed a niche where someone had once bricked up two doors, the map trembled and for a second showed a corridor where they could only see a wall. - 'Master Radwan used to say that reality here is like glass with added ash,' Simon muttered, pointing with his lantern to the micro-cracks in the plaster. - You can always soften it with a little heat. - And then the cracks remain,' Lira added and immediately reprimanded herself in her mind for the unnecessary shadow in her voice. Finally they reached the vestibule of the Basilica. The entrance did not resemble a gate, more like a crack in the salt rock that formed itself into an arch. Up close, it was clear that the salt was not just white: it had pink veins, grey patches of old water, tiny inclusions in which air bubbles had been trapped for years. Beyond the crack there was a chill, different from the night - a chill that had a memory. Inside, the sound was thicker. The salt played on its own edges, as if someone had run a moist finger over it. Lira stopped, feeling the map briefly stick to her skin. She shuddered. The pulse of the map and the breath of the Basilica began to cohere. On the floor, which had not been touched by footsteps for many years, lay a shattered pillar of light - narrow, uncertain, like a smudge from scratched glass. There floated a speck, smaller than a fist, yet heavy on the eyes. A splinter of sky. It did not give off the usual glow; it seemed to be the surrounding darkness becoming clearer, sharper, like grain in old photographs. - 'Don't touch,' hissed Simon, though Lira didn't even flinch in that direction. - Not yet. Instead of chipping away, she looked at the apse. Deep inside, in the shadows, a door was outlined. There were no locks, just three openings, each carved into the shape of a different constellation. The first resembled the Paddler, the second the sloping trapezoid of the Clock, the third the short arc of the Dissent. Lira felt a dry laugh rise in her throat: these were figures from the margins of Radwan's maps, the ones he usually made when he was thinking of something else. - 'These aren't just constellations,' she whispered. - 'They're the layout of our streets, only inverted and folded into the sky. Simon brought the lantern closer. The flame wavered, reflecting in the salt reliefs as if they were milk mirrors. On the map, the lines ceased to be lines - they became threads that could be pulled, pulled through the holes, as through a needle's eye. Lira raised the parchment to breast height. The map floated with her, as if it had a lighter gravity. - 'I'll try to tune,' she said, and her voice sounded alien in the large space. - 'See? If I guide the Paddler through the first trace.... - Put out if they start screaming,' Simon interrupted, having a crackle of salt in mind. - 'Screaming means the material won't hold. Lira nodded, though she wasn't sure she could hear him fully. She concentrated on what was happening between the map and the door. The threads of the drawing were searching for a way in, twitching at the edges, snagging on stars carved in the salt. Underfoot, deep down, something rustled. As if the Milky Sea had rolled in its sleep, impatient with someone's movement. All glare was extinguished for a moment. For a second all they had was darkness and the cold breath of the Basilica. Then Simon's flame burst suddenly with sapphire, and three modest, barely visible lights appeared on the door, each in the centre of one of the openings. Lira pulled gently on the thread of the Paddle; she felt as if someone was holding the end on the other side. She pulled on the Clock, feeling the resistance exactly as the gears do when they are moved out of season. The shatter left a mark on the parchment like a wet hair. The lights in the holes flared a ton. - 'Just a moment more,' she whispered to the map, not to Simon. - Another centimetre. And then the salt began to weep. Wet spots appeared on the edges of the door, which immediately turned into streaks of iridescent moisture. Drops fell to the floor with the sound of thin glass. A sound that was neither music nor movement answered from the depths of the door: a drawn-out, single beat, like the heart of a foreign instrument. Simon raised the lantern higher. Shadows shifted across the faces of carved angels whose wings had been clipped from the salt to prevent them from flying away. Lira held her breath and tightened the last thread. Something on the other side pulled back with equal force. The door vibrated, and then - from beyond its edge - a streak of light emerged, not like that from the splintering, but denser, warmer, lined with gold. It moved across Lira's face like a touch. The parchment suddenly became hot and very heavy, as if all the evening steam had seeped into it, which it had not. At the same moment, a second light came on in the nave behind them, as tiny as the eye that had just opened. - 'Lira...' said Simon, but the rest of the word stuck in his throat as the salt struck such a chord that the roof groaned. Someone, or something, on that side had tuned the last note.
