Claire stepped off the trail to check her map, and that was the mistake. One wrong turn on day two. Now the sun was setting on day forty, and her ripped shirt clung to her ribs. She kept walking. Someone was still out there looking. She had to believe that. Her pack felt lighter than it should. She had eaten the last berries that morning. Two had been the wrong kind, twice now, and somehow she was still breathing. Dark luck, she thought. The kind you don't get to spend twice in a row. She stopped at a dry stone well half-swallowed by weeds. She lowered her canteen anyway. Nothing came back up. Claire laughed once, sharp and tired, and sat down on the cracked rim. That was when she saw it. A scrap of pink fabric flapping on a thin pole, planted in the dirt just past the well. A marker. Faded, beaten by wind, but placed. By a person. For her. Claire's hands shook as she pulled her belt free and wrapped it around a fallen stick. She drove the stick into the ground beside the flag. A sign back. I was here. I am here. Find me. She stood and followed the direction the flag pointed. Someone was still looking. She had proof now. And she would walk toward them until they met in the middle.

Claire followed the flag's direction until the trees thinned. The faded pink scrap waved behind her like a hand letting go. Ahead, the ground opened. A hole. Dark, round, and waiting. A rope dropped into it, tied off to a big stone wrapped in old cord. Above the hole sat a small canopy on four wooden poles, the cloth sun-bleached and sagging. Claire knelt at the edge. Her pack slid off her shoulder and thumped beside her. Someone had built this. Someone had climbed down. Maybe to hide. Maybe to live. Maybe to die. Then she saw the jacket. Khaki, folded neat on a flat rock. A rescue badge stitched on the chest, bright as a promise. Her breath caught. A searcher had been here. A real one. She ran her fingers along the rope. It held. The stone held. She thought of climbing down to hide, to rest, to finally stop. But the jacket changed everything. The searcher had gone down. The searcher had not come back up. Claire stood. She did not climb down. She tied her ripped sock to the canopy pole so anyone passing would see, then shouldered her pack. Whoever wore that jacket needed her now. The hunted had become the hunter. She stepped past the hole and kept walking, the rope creaking softly behind her like something breathing.

Claire walked twenty steps past the hole before she stopped. The rope creaked behind her. The jacket sat on its rock like a question she couldn't leave alone. She turned around. Whoever wore that badge was down there. And she had legs that still worked. She knelt by the rope and tested it again. Halfway down, the fibers were frayed almost through. One hard pull and it would snap. She swore under her breath. Then she pulled off her ripped shirt, shivering as the air bit her skin. She tore a long strip and bound the weak spot tight, knotting it twice. The shirt bloomed around the rope like a bright bandage. Clipped near the top knot, a small cloth tag swung in the breeze. Numbers were stamped on it in faded red. One-four-five. A tracker's tag. Proof someone real had been here, someone who counted things, who left records. She pressed her thumb against the numbers like a heartbeat. She tied off the loose end of her shirt to the wooden pole holding the canopy. Leather strips already wrapped the post from someone before her. Her blue scrap joined them, a marker for anyone who came after. If she didn't come back up, they'd know she went down. Claire gripped the rope and lowered herself over the edge. The shirt-knot held. The frayed rope held. Her boots scraped stone walls slick with damp. The light above shrank to a coin. Somewhere below, water dripped. Somewhere below, maybe, someone was breathing. Her boot touched bottom. She let go of the rope and turned in the dark. A faint shape lay against the far wall. Not moving. She stepped toward it, and the coin of light above her flickered as something passed over the hole.

The shape didn't move. Claire crept closer, heart pounding, and her boot splashed into shallow water. She froze. A river ran through the cave floor, narrow and bright, winding past the still figure into the dark. She knelt by him. He was breathing — shallow, but breathing. Alive. She didn't know his face, but the badge on his collar matched the jacket above. One-four-five. He'd come for her, and he'd fallen. She pressed her palm to his forehead. Hot. Too hot. She needed clean hands, a clear head, something other than forty days of grime between her and helping him. The river slid past, cold and clear. She made herself a deal. Five minutes. Just enough to think. Claire pulled off her boots and set them on a flat rock. The leather was cracked, the soles worn paper-thin. They had walked her through everything. She folded her ripped shirt and shorts on top, a sad little pile of who she used to be. Her pack leaned against the stone beside them. The water bit when she stepped in. She gasped, then sank to her shoulders. Dirt lifted off her skin in dark ribbons. She scrubbed her arms, her face, her tangled hair. For one strange second, she felt human again. She watched the tracker's chest rise and fall across the stones. She wouldn't leave him. She couldn't carry him up that rope alone, either. But she could keep him alive until someone came. She could be the one who stayed. Claire climbed out, shivering, and reached for her clothes. Then the coin of light above the hole flickered again. A shadow. A voice — far away, muffled by stone — calling down. Someone was up there. And she was naked, dripping, with a wounded man at her feet.

The voice above broke off. Before Claire could call back, the river behind her surged. A wall of water rose where the current had been calm, swirling into a tight, glowing ring — a nest of liquid coils that hissed against the stone. Something huge uncoiled from inside it. Green scales. Yellow eyes. A claw closed around her ankle and yanked her off her feet. She hit the water hard. The creature dragged her down the shallow channel, past the unconscious tracker, into a wider pool ringed by weathered rocks and old rusted gear. Its claws hooked her shirt and tore. Her shorts went next, ribbons spinning away on the current. What was left of her clothing drifted to the bank in red-streaked, clawed scraps. The monster pinned her to the cave floor. Cold stone bit her back. A long forked tongue dragged up her stomach, slow and curious, then across her collarbone. Claire choked on a sob and a laugh at once. Forty days of berries and bad luck, and this was the part that broke her. Not yet, she thought. Not like this. Her hand scraped sideways and closed on something metal — a rusted spike half-buried in the grit. She drove it up into the soft place under the creature's jaw. It reared back, shrieking, green blood spattering the stone. Claire rolled, scrambled, and kicked at its snout with her boot. The thing thrashed once, slid backward into its glowing ring of water, and the whole nest collapsed in a hiss of foam. She lay shaking on the cracked floor, naked except for her boots and the wet rope of her hair. The tracker hadn't moved. But the voice from above was closer now, calling down again — clearer, a man's voice, urgent. Someone was coming down the rope. Claire crawled to the tracker and pressed her body against his side, sharing what little warmth she had. She pulled the clawed scraps of her shirt over them both. "Hold on," she whispered, to him, to herself, to whoever was climbing down. "I'm still here. Don't stop."

The rope creaked above her. Claire pressed closer to the tracker's side, the clawed scraps of her shirt pulled across them like a thin blue shield. Boots scraped stone. A man was halfway down now, a red-lidded kit strapped to his hip, gauze packets glinting through the clear plastic. He had come ready to find her alive. Then his face changed. He stopped on the rope, staring at her stomach. "Don't move," he said. "Claire. Don't move." She looked down. Beneath her skin, something rippled. A slow bulge traveled from her hip toward her ribs, where the creature's tongue had dragged. Her breath caught. She thought of the glowing ring of water, the swirling nest the monster had collapsed back into. Eggs. It had been trying to plant eggs. "Get it out," she whispered. But her hand drifted, instead, toward the river. The water shimmered where the nest had been. A faint glow pulsed back, weak and waiting. Something in her chest pulled toward it. She did not want to leave. She wanted to crawl back to the pool, to lay down in the swirling water, to let whatever was inside her finish becoming. The man dropped the last few feet and landed hard. He snapped open the kit, tore a gauze packet with his teeth, and pressed cold antiseptic against the moving lump. "Stay with me," he said. His hand was steady on her stomach. His eyes were steady on hers. "I didn't climb down here to lose you." Claire turned her face away from the glowing water. It hurt to do it. But she fixed her eyes on him instead — on the man who had not stopped looking — and she nodded once. "Cut it out," she said. "I'm still here."

The rescuer pressed the gauze tighter, but the pull from the water was too strong. Claire shoved his hand away. "Wait," she gasped. She crawled toward the shimmering pool. The cave walls leaned close around her. The river glowed brighter as she neared, as if it knew her name. The nest rose to meet her. Curling ribbons of water lifted from the surface, forming a delicate dome of swirling currents. Inside it, soft lights pulsed like a heartbeat. Then the river broke open. The colossal scaled creature surged up, emerald plates dripping, yellow eyes fixed on her belly. "Claire, get back!" the rescuer shouted. He scrambled forward, knife out. But the creature did not strike. It lowered its huge head and made a low, wet sound — almost a question. Beneath Claire's skin, the eggs answered. They rolled toward the surface like they wanted out. She understood then. She was the last nest. The spike under its jaw had hurt it badly, and there were no others. If she cut the eggs out here, the species ended tonight. If she kept them, something in her ended instead. Claire turned to the rescuer. His hand was shaking on the blade. "Not all of them," she said. "Take half. Leave the rest in the water." She pulled up her torn shirt. He stared at her, then at the creature, then nodded once. He cut carefully. Slimy, pearl-colored eggs slid into his palms, glowing soft greens and pinks. He set them gently into the swirling dome. The creature curled around them and sank. The pull in her chest finally loosened. Claire sagged against the rescuer's shoulder, half her burden gone, half still moving inside her. "You stayed," he whispered. She closed her eyes. "So did you."
