Gearspark Aviatrix bolted the salvaged core engine to a new frame on the rooftop, teal light bleeding through the seams of her armor. Yesterday the rest of the machine hit the harbor floor. The engine survived, and she had rebuilt around it in one night. She meant to fly it into the storm-wall by dawn: the churning gray band that circled the sea and had swallowed every pilot who tried to reach the lost continent behind it. She wanted her name on that crossing. She wanted it enough to launch on guesses. She had no data on what the wall did inside itself, only the wrecks that came back in pieces, and her wing spar was thin enough that a wrong gust would fold the craft in half. A boot scraped the gravel behind her. Storm Grit climbed off the fire escape with bandaged hands and yellow eyes that did not blink enough. Gearspark did not know her. Storm Grit spoke first. "I know about storms." She said her curse pulled her under whenever one came within a day's reach. She could feel pressure the way other people felt hunger. She named the wall's inner pattern in four flat sentences: a calm shell, a shear layer at two hundred feet, an updraft column at the center, a second shear on exit. She said it the way someone reads a receipt. Gearspark grabbed a grease pencil and wrote it on the wing itself. Then she asked why. Storm Grit shrugged. "Velvet sent me. Says you owe her now." Below them, on a lounge balcony one roof over, a woman in black watched with her arms folded. Velvet Mirage raised two fingers in a small wave, patient, unhurried, already counting what the favor would cost. Gearspark lit the engine. The frame shook and held. She climbed to two hundred feet, cut hard through the first shear the way Storm Grit had described, and rode the updraft column until her goggles fogged from the pressure change. The second shear kicked the tail. The craft held. She punched through the far side of the storm-wall into clean, cold air and saw, for one full minute, a dark shoreline no chart had ever shown. Then a strut cracked and she turned back, threading the same seam home. She landed on the rooftop with half a wing and a working chart of the crossing in her head. Storm Grit was already gone. Velvet Mirage was not. She lifted a glass across the gap and mouthed one word Gearspark could read even from here: soon.

Gearspark spread her grease-pencil notes across the workbench before the memory could blur. Under the patchwork tarp of her rooftop workshop, the salvaged core engine ticked as it cooled. She flattened the chart with a wrench: shear layers, updraft column, the ragged smear where a dark shoreline had shown itself for one minute. She traced the line with her thumb. It was hers. She had flown it. She wanted to fly it again before the wind forgot her. A heel clicked on the gravel behind her. Velvet Mirage stepped under the tarp, out of the sun, and set a thick black envelope on the bench beside the chart. Dark wax sealed the flap. She did not sit. "Keep the map," Velvet said. "Find the truth." Gearspark looked up. "I already know the truth. I flew it." "You flew a route." Velvet tapped the envelope with one finger. "Someone else flew it first. Years ago. I want to know who still remembers." Gearspark broke the seal. Inside were old field reports on soft paper, stamped and re-stamped. Pilots describing strange lights past the storm-wall. A harbor master's note about a boat that came back empty with the log torn out. A dated sketch of a shoreline that matched the smear on her chart almost line for line. Her stomach dropped a floor. She set the papers down carefully. "You want me up again." "Not to prove the crossing." Velvet's voice stayed even. "To see who watches when you go. Lights on the water. A second craft in the shear. A signal answering yours. Anything." She paused. "You already owe me for the first flight. Call this the same debt, paid twice." Gearspark almost said no. The wing was half gone. The strut had cracked on the way home. A second run on the same rebuild was how pilots ended up under the harbor with their engines. She looked at the envelope, then at the chart, then at the sketch that someone else had drawn before she was born. "I'm not repairing it," she said. "I'm rebuilding it stronger. Thicker spar. Double strut. A dampener on the tail so the second shear doesn't kick." She rolled the chart and tucked it inside her jacket. "Give me two days." "You have them." Velvet turned to go, then stopped at the edge of the tarp. "Gearspark. Fly high through the first shear this time. If someone is waiting, they'll be waiting where you were." Gearspark nodded once. Velvet left. She pulled a fresh spar off the rack and clamped it into the vise. The core engine ticked. The reports lay open on the bench, one dated sketch faceup, the shoreline drawn by a hand she did not know. Her name was not going to be first. It was going to be second, or it was going to be the one that found the first. She picked up her file and started cutting.
