Chapter 13 The Ink of Lumen

The ink of Lumen was not like any ink Clary had ever used. It was not made from iron gall or carbon or dye. It was made from light — from the pale, enduring luminescence that filled the city, captured and condensed into a liquid that flowed from the river and pooled in the hollows of the stone streets and rose like mist from the surfaces of books and maps. A demonstration preceded the instructions. One of the Council figures unclasped a hollow stylus from its robe, held it up to the sourceless light, and let the luminescence run down into the barrel like honey finding a spoon. What gathered there was not white and not gold and committed to neither; it moved as if it still belonged to the sky it came from, homesick and obedient at once. "Light remembers being free," Maren murmured beside her, unasked. "Ink is only light that has agreed to hold still. Treat it gently and it will hold still for you." Clary stood at the edge of the river, a blank sheet of paper in one hand and a small glass vial in the other — a vessel the Council had given her, crafted from a material that was neither glass nor stone nor metal, but something in between, something that had been made in Lumen and would exist only in Lumen. She dipped the vial into the river. The liquid that rose into it was luminous, glowing faintly, shifting between white and gold and a color that had no name. "Write," said the figure who had spoken to her earlier. "Draw. Show us the way out." Clary set the vial down. She picked up a pen — her own pen, the one she had brought from the world above, the one she had used to draw her first map, the one that had led her to Tamsin's field and then to this place. She dipped the pen into the ink. The ink clung to the tip, glowing, pulsing, alive. The vial was warm in ways glass had no right to learn. When Clary uncorked it the smell reached her — ozone and libraries and, absurdly, her school's biology storeroom — and her own reflection looked back up at her, curved and slightly delayed, as if the liquid were considering whether to show her her face today or somebody else's. Her pen hovered. One breath. Two. Then she set the nib down the way her mother's marginal notes had taught her to set a bearing: decisively, and with respect for the error bars. She began to draw. She drew the river — not the river of Lumen, but the river of the world above, the river that ran beside the field where Tamsin had disappeared, the river that had been dragged and probed and searched by police and volunteers and cadaver dogs. She drew the field. She drew the trees. She drew the symbol — the circle bisected by a diagonal line — but she drew it differently this time, not as an entry point but as an exit point, not as a door that opened inward but as a door that opened outward, a threshold that led back to the world she knew. She included things no exit required. The bus shelter with its shattered pane, drawn because Tamsin had once waited there forty minutes in the rain and laughed the whole time. The scratch on the kitchen table shaped like a river delta. Their father's green door. If the map was going to be a bridge, Clary reasoned, it ought to be anchored at both ends — and anchors, in her family's tradition, had always been made of ordinary days. The luminous ink took each homely line and brightened it, as if recognition were a fuel. The ink moved on the paper. It flowed faster than gravity should allow. It filled the spaces between her lines, shading and coloring and defining, creating a map that was not a representation of a place but a bridge to a place, a map that existed not on the page but in the space between the page and the world, a map that was, in every sense, a key. "Keep going," the Council figure said. "Do not stop. Do not hesitate. The map is forming. You are forming the map. You are the map." Clary did not understand what the figure meant, but she did not stop. She drew until her hand cramped, until the pen ran dry, until the last drop of luminous ink had been transferred to the paper, until the map was complete. The last stroke she saved for the threshold itself — the circle bisected by its line — and when she drew the diagonal, the ink resisted for the length of one heartbeat before yielding, the way a lock yields to its final tumbler. Then the whole sheet exhaled. Light moved beneath the surface of the paper like wind beneath wheat, settled, and waited for her with the patience of a held door. She set the pen down. She looked at the map. The map was beautiful. It was also terrifying. It showed the world above — the field, the trees, the river, the symbol — but it also showed something else. It showed Lumen, or a part of Lumen, or the impression of Lumen that existed in the world above, the echo of the city that lived in the gaps between maps, the place where the two worlds overlapped and bled into each other and became, for a moment, indistinguishable. The double exposure resolved as she watched. Look one way and it was Devon: hedge, field, river, rain-shadowed hills behaving themselves. Look again and the same lines composed a city, avenues where lanes had been, towers of pale masonry rising exactly where cow parsley rose at home. Neither image would dismiss the other. That, Clary understood with a chill that was almost excitement, was not a flaw in the drawing. That was the truth of the two places, rendered honestly at last: they had always occupied the same ground, arguing. And at the center of the map, where the symbol was, was a figure. A small figure, drawn in exquisite detail, with dark hair and fierce eyes and a stubborn set to the jaw. Tamsin.
