Mirella knelt in the moss and rinsed her blue thread bracelet in the slow swamp water. She had worn it since the day someone left her here. She still did not know who. She had spent years asking that question, and the swamp had never answered. A wet splash broke the quiet. An otter climbed onto the bank, its eyes shining a strange, sparkling blue. "I know who left you in the moss," it said. Mirella froze. The bracelet dripped in her fist. The otter dropped a single orange-tinted ruby at her feet. More glittered behind it, spilling from a den ringed by a thick wall of bright, many-flowered blooms — twelve kinds at least, planted by hands that had bargained here before. "Proof I pay my debts," the otter said. "But first, you fetch something for me." It described the favor. Deep in the flooded caves, a guardian slept beside a purple crystal sphere. The otter wanted the sphere. To take it, Mirella would need the frostfire spear lodged in the dam upstream — and she would need to wake the thing guarding the orb. Mirella looked at the bracelet. She looked at the ruby. Every other trail had gone cold. She had promised herself she would not turn back. She closed her fingers around the gem and stood. "I'll do it," she said. The otter grinned and slid into the water. "Bring me the sphere. Then I'll give you a name." Mirella tucked the ruby into her pocket beside the bracelet. The search had a price now, and she had agreed to pay it.

Mirella followed the stream until it slid into a wide stone mouth. Vines hung over the entrance. Water churned blue in the dark beyond. She had found the flooded caves the otter spoke of. But something stopped her before she stepped inside. A warning was scratched deep into the rock beside the opening. The lines were jagged and rough, cut by a hurried hand. Mirella leaned closer. Her breath caught. The pattern matched the weave on her wrist. She pulled the blue thread bracelet free and held it up beside the carving. The bracelet glowed faintly, its waves and lines pulsing soft teal in the dim cave light. Every curve on her wrist matched a curve in the stone. Whoever left her in the moss had also stood here. Whoever left her had tried to warn someone away. Mirella's knees gave. She sank into the wet moss at the cave mouth and pressed her hand to the etching. A memory rose she had not touched in years. A stick doll with leaves for hair, tucked beside her in the moss as a baby. A shell bowl of rainwater set near her head. Small kindnesses left by hands that had still chosen to leave. She scraped at the moss below the warning. Her fingers struck something hard. She dug it free. The little leaf-haired doll lay in her palm, faded and damp, the green leaves brown at the edges. The same doll. Left here, at this entrance, not in the swamp where she was found. Mirella closed her fist around the doll. Her parents had not abandoned her at the swamp first. They had come here first, and run. The warning was theirs. The cave ahead held whatever they had feared. She tucked the doll into her pocket beside the ruby and stood. The bargain had just become a path straight toward them.

Mirella stepped past the warning and into the cave mouth. The air turned cold. Just inside, she found a ragged blanket bunched against the wall, half-burned sticks scattered beside it, and pale scraps of paper weighed down by stones. A camp. Hasty. Left in a hurry. She knelt and lifted one of the notes, but the ink had blurred to gray smears. A sound clicked behind her. She turned. A bird the size of a hound stood between her and the daylight. Its feathers shone blue and purple, set with chips of ruby that caught the dim light. It did not screech. It only watched her with steady red eyes and shifted one clawed foot, blocking the way out. Mirella raised both hands slowly. The bird tilted its head toward the deeper dark of the cave, as if pointing. She understood. It would not let her leave. It wanted her to go further in. She walked backward, careful, until her shoulder bumped stone. She turned. A great rock rose from the cave floor, taller than she was. Lines glowed across its face in pale blue, like cracks full of moonlight. In the center, cut deep and clean, was a single word. A name. Her breath stopped. She knew the shape of those letters from nowhere, and yet her hand lifted to trace them as if she had always known. The carving was older than the warning outside. Cut by a different hand. Whoever had scratched the rushed warning at the entrance had been running from this name. Her parents had not made this. They had read it, and fled, and left her behind because of it. Mirella pressed her palm flat against the glowing letters and whispered the name aloud. The gemstone bird behind her ruffled its feathers once, then settled, as if a promise had been kept. She did not know yet whose name she had spoken. But she knew now that her parents had run from a person, and that person had been here first. She tucked the blurred note into her pocket and faced the dark ahead.

The whispered name still hung in the cold air as Mirella stepped past the glowing stone. The cave opened into a wider chamber. A shallow pool sat in the center, its surface trembling with reflected light. Fireflies drifted above it in slow loops. Her bracelet pulsed once against her wrist, the teal threads brightening as if answering the water. She knelt at the edge. The name she had spoken rose in her throat again, softer this time. The pool flared. And something inside her broke open. She was small. Someone was carrying her fast through the dark. A woman's hair brushed her cheek, tied back with a pale yellow scarf covered in butterflies and tiny sparkling stones. A man ran beside them, his breath ragged. They were not strangers. They were hers. She remembered the smell of woodsmoke and crushed mint on their clothes. She remembered laughter, before the running. She remembered being loved. Mirella gasped and pressed her hands to the stone. The memory kept coming. She saw the chamber she now stood in, but lit by torches. She saw the pale figure rising from the water at the far end, a tall statue of a person seated in the pool, eyes closed, hands folded. Her mother had turned her face away from it. Her father had whispered the same name carved on the stone, and his voice had shaken. They had set her down. They had run the other way to draw it off. They had meant to come back. The memory snapped shut. Mirella was kneeling again, alone, shaking. Across the pool, half-sunk in the shallow water, lay the yellow scarf. Faded now. Butterflies dulled. It had waited here all these years. She lifted it with both hands. Her parents had not thrown her away. They had hidden her and run, and something had stopped them from returning. The not-knowing was gone. In its place sat a colder question, heavier than the first. Whatever they had feared was still here. And it knew her name now too.

Mirella folded the faded scarf into her belt and stood. A flash of color cut across the chamber. The jeweled bird landed on a gnarled branch jutting from the cave wall, its ruby-tipped wings folding tight. It did not screech at her. It stared past her, toward the entrance, and made a low warning sound she had not heard before. She followed its gaze. Then she understood. The bird had not chased her deeper to trap her. It had pushed her away from the mouth of the cave. Away from whatever waited there now. Mirella crept back along the passage, keeping low. Near the entrance, she froze behind a slab of stone. A hooded figure stood in the wreckage of her old camp. Pointed ears. Dark eyes under the hood. The blanket she had found days ago was shredded at its feet. The warning her parents had carved into the rock was scratched out, fresh white lines through old grooves. The shadowy elf turned its head slowly, listening. Beyond it, deeper than she had ever gone, blue light pulsed from a side tunnel she had missed. She could just see the edge of a pale stone seat inside, sapphires glinting along its arms. A throne. And resting on its seat, a glowing purple sphere wrapped in crystal. The thing the otter wanted. The thing her parents had run from. The bird shrieked behind her. The elf's head snapped up. Mirella bolted sideways into the side tunnel, snatched the cold sphere off the throne, and pressed it to her chest. It hummed against her ribs like a second heart. She ran. The jeweled bird swept past her shoulder, driving the hooded figure back with beating wings. Mirella did not stop until the cave mouth was far behind her. She had the sphere. She had her mother's scarf. And now something with pointed ears and patient eyes knew exactly who she was, and was already following her trail.
