Text to rewrite: <text words="381"> The market square buzzed with the sound of a hundred voices. Elena pushed through the crowd, her satchel clutched against her chest. She knew the merchant would not wait — he never waited for anyone, least of all a girl from the outer ring. "You're late," Gregor said, without looking up from his ledger. He ran a thick finger down a column of numbers and frowned. Elena set the package on the counter. "The bridge was out. I had to take the long way around." "Not my problem." He unwrapped the cloth and held the crystal up to the light. It caught the sun and threw tiny rainbows across the stall's canvas roof. Gregor's frown deepened. "This isn't what I ordered." She had expected this. The old man always found something to complain about, whether the goods were perfect or not. Elena crossed her arms and stood her ground. "It's exactly what you ordered," she said. "Blue quartz, uncut, from the northern mines. I watched them pull it from the rock myself." Gregor turned the crystal slowly, examining every facet. He brought it close to his eye, then held it at arm's length. Elena thought he looked like a jeweler appraising a diamond, though Gregor dealt in stranger things than jewelry. He set the crystal down and sighed. "Fine. But next time, wrap it properly. The edges are exposed." He reached beneath the counter and produced a small leather pouch. The coins inside clinked as he slid it toward her. Elena scooped up the pouch and weighed it in her palm. It felt light. She loosened the drawstring and counted: eight silver crowns. They had agreed on ten. "We agreed on ten," she said flatly. "That was before the bridge fee went up." Gregor smiled — a thin, practiced smile that never reached his eyes. "Take it or leave it." She took it. She always took it. The outer ring didn't offer many choices, and Gregor knew that as well as she did. Elena walked out of the market and into the narrow lanes beyond. The sun hung low over the rooftops, and the shadows stretched long across the cobblestones. She slipped the pouch into her satchel and quickened her pace. If she hurried, she would reach the bridge before dark. </text>

The market square bustled with the chatter of a hundred people. Mirabel navigated the sea of bodies, her bag held tightly to her torso. She was aware that the trader would not linger for her — he never lingered, especially not for a girl from the outskirts of the city. "You're tardy," Aldric grumbled, eyes unwavering from his record book. He dragged his bulbous digit down a row of figures and scowled. Mirabel laid the bundle on the table. "I detoured; the bridge was out." "That's not my concern." He unwrapped the fabric and held the gem to the sunlight. It danced with rainbow reflections off the sunbeams, illuminating the canvas stall covering. Aldric's furrow deepened. "This isn't the item I requested." She wasn't surprised by this declaration. The elderly man perpetually found fault, regardless of the items' condition. Mirabel defiantly crossed her arms. "It matches your order precisely," she asserted. "Raw lapis lazuli from the northern mines. I witnessed its extraction." Aldric methodically rotated the crystal, inspecting every angle. He brought it close to scrutinise it before setting it down. Mirabel thought he resembled a gemologist assessing a precious stone, though Aldric's trade delved into peculiar realms beyond jewellery. He exhaled and acquiesced, "Alright, but next time, ensure it's properly wrapped. The edges are unprotected." He delved beneath the counter, producing a diminutive leather purse, the coins within clinking as he pushed it towards her. Mirabel grabbed the pouch, its lightness palpable in her grip. She untied the cord and counted: eight silver pieces. Ten had been the agreed-upon price. "Ten was the agreement," she stated flatly. "Well," Aldric replied with a feigned smile that didn't touch his eyes, "the toll has risen since we last spoke. You can accept or refuse." She accepted. She always did. Where she lived, choices were scarce, a fact Aldric understood as well as she did. Mirabel departed the market, striding into the cramped alleyways beyond. The sun was low on the horizon, casting long shadows on the cobblestone streets. She nestled the pouch into her satchel and hastened her steps. If she hurried, she would traverse the bridge before nightfall.
