Lyra Brightgaze had wasted six days asking the wrong people about sight-restoring magic, and the healer in the market had just laughed her out of his stall. She walked off with her hood down and her scar bare, the way she always did. Her left eye was blind, but it felt the sun on her cheek and the cold of the brass coins in her pocket. It also felt magic. The eye had been dim since the fight, the one she would not talk about, and every quiet day let the scar settle deeper into her face. She needed a lead before the dimness became permanent. She stopped at the fountain to think. A purple-skinned elf with a slashed eye drew stares, and she had learned to use them. She asked a flower-seller where strange remedies came from. The woman pointed past the temple road, toward a low district where the lamps stayed lit at noon. Lyra dropped a coin in her basket and went. Two streets in, her blind eye went hot. Not the warm prickle from a charm-stall. A hard, steady burn, like standing too close to a forge. She turned toward it. The heat pulled her through an arch in a stone wall and into a garden ringed by pale columns. Plant beds glowed from under the soil. A woman in green knelt among the roots, pinching dead leaves. She looked up at Lyra's scar and did not flinch. "You feel it," the woman said. Lyra nodded. The woman stood and brushed dirt from her hands and walked to a shelf set into one of the arches. She took down a crystal bottle. Purple liquid moved inside it in a slow spiral, lit from within. Lyra's blind eye burned so hot she pressed her palm against it. The gardener held the bottle out but did not let go. "This isn't the cure," she said. "It's a compass. It points to what made it. If you want your eye back, you follow the pulse." Lyra asked where. The gardener's mouth tightened. "The sellers gather in a cavern under the black hills. Bring coin. Bring better sense than you have now." Lyra paid what the woman asked, which was most of what she had. She walked out with the bottle wrapped in cloth against her chest. Through the cloth, through her ribs, the heat pulsed against her blind eye in a steady beat, and each beat pointed the same way, toward the hills outside the city. She had a direction now. She also had no money for an inn, a warning she did not understand, and a road that led to people who traded in magic the healers would not name. She started walking before sundown.

Lyra walked the hill road two days before she saw the sign. The bottle pulsed against her ribs in a steady beat, and the cloth she wrapped it in had stopped hiding the glow. Purple light leaked through the weave and lit her chin at night. She kept walking because she had no coin for a wagon and no other lead. The road climbed between cracked orange cliffs, and the wind carried the smell of woodsmoke that did not match any town on her map. The smoke came from a tin-roofed shed at a bend in the road. A painted board read SUPPLY STATION in faded red. Fuel drums sat stacked by the door. No one stood at the counter. A leather satchel lay open on the dirt, its lining glowing faint green from moss packed inside. Someone had cut the strap. Lyra stopped walking. She pressed her hand over the bottle to smother the light and stepped off the road into the rocks. Her blind eye went hot, but not from the bottle. The heat came from above. She looked up. A narrow ledge jutted over the road from the cliff face, half hidden by a lip of stone. Two men crouched on it. One held a crossbow. The other held a charm that flared when he turned it toward her. They had been watching the shed, waiting for the glow to come close enough to drop on. Lyra ran back the way she came, off the road, into a dry gully. The crossbow bolt struck rock behind her. She crouched under an overhang and unwrapped the bottle. The purple liquid spun hard toward the hills, past the bandits, past the cliff. She needed the light gone. She scooped wet clay from the gully floor and packed it around the glass until only her palm felt the pulse. The glow died. She held still and listened. Boots scraped stone above her, then moved off down the road toward the shed. She waited until the boots were gone, then climbed the gully wall on the far side and cut across the slope away from the road. The clay dried and cracked but held. Her blind eye still burned toward the hills, steady as before. She walked through scrub for the rest of the day, scratched and thirsty, with no road under her feet and no water in her pack. By dusk she found a goat track that ran the same direction the bottle pulled. She had kept the bottle. She had lost the road. The bandits would tell others a glowing elf had slipped them, and the next watch would look harder. She sat against a rock and chewed the last of her bread. The clay on the bottle pulsed under her hand. The hills rose ahead, dark against a red sky, and somewhere inside them was the cavern the gardener had named.
