User/Human
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 bustling market square echoed with the chatter of a hundred voices. Mirabel navigated the crowd, tightly holding her satchel close to her body. She was aware that the merchant would show no mercy on her tardiness, especially as she came from the outer ring. "You're late," Aldric remarked, his gaze fixed on his ledger. He glided a thick finger down a column of numbers, his brow furrowing. Mirabel placed the package on the counter. "The bridge collapsed. I was forced to take a detour." "Not my concern." As he unravelled the cloth, he held the crystal up to the sunlight, causing miniature rainbows to dance across the stall's canvas roof. His frown intensified. "This isn't what I requested." Mirabel had anticipated this. The old man always managed to find something to grumble about, regardless of the quality of the goods. She confidently crossed her arms. "It's precisely what you requested," she asserted. "Uncut blue quartz, straight from the northern mines. I oversaw its extraction from the rock myself." Aldric methodically turned the crystal, examining each facet. He scrutinized it closely before holding it at arm's length. Mirabel noted his resemblance to a jeweller assessing a diamond, although Aldric's trade veered towards the peculiar beyond the realms of mere jewellery. Laying the crystal down, he sighed. "Alright, but next time, secure it properly. The edges are exposed." He reached below the counter, retrieving a modest leather pouch, its contents jingling as he pushed it in her direction. Mirabel grabbed the pouch, testing its weight in her palm. It felt lighter than expected. She loosened the drawstring and counted: a mere eight silver crowns. They had initially agreed upon ten. "We agreed upon ten," she stated bluntly. "That was before the bridge fee increased." Aldric's smile was insincere, never reaching his eyes. "Your choice." She accepted it. She consistently accepted his offers. Living in the outer ring left limited options, a reality Aldric was well aware of. Emerging from the market, Mirabel ventured into the adjoining narrow lanes. The setting sun cast lengthy shadows across the cobblestones while hanging low above the rooftops. She tucked the pouch into her satchel and picked up the pace. By hurrying, she would make it to the bridge before nightfall.
