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 voices of countless people. Mirabel navigated through the throng, clutching her satchel protectively. She was aware that the merchant wouldn't tolerate delays—his impatience knew no bounds, especially when it came to a girl from the outer ring. "You're late," Aldric remarked, his gaze fixed on his ledger. His thick finger traced down a column of numbers, followed by a frown. Mirabel placed the package on the counter, explaining, "The bridge was down, so I had to take a longer route." "Not my concern," he replied, unwrapping the cloth and holding the crystal up to the light. Sunlight danced through the crystal, casting miniature rainbows across the stall's canvas roof. Aldric's frown deepened. "This isn't what I requested." Mirabel was prepared for this, as the older man always found reasons to complain, regardless of the quality. She crossed her arms, refusing to back down. "It's precisely what you ordered," she asserted. "Blue quartz, uncut, from the northern mines. I witnessed its extraction from the stone myself." Aldric slowly rotated the crystal, examining each facet with care. He brought it close to his eye and then extended his arm to view it from a distance. To Mirabel, he appeared like a jeweler scrutinizing a diamond, though Aldric's trade extended beyond jewels. Setting the crystal down, Aldric sighed. "Alright, but next time, ensure better wrapping. The edges are unprotected." He reached below the counter and retrieved a small leather pouch, its contents clinking as he slid it towards Mirabel. Mirabel took the pouch, feeling its lightness in her palm. Loosening the drawstring, she counted eight silver crowns, falling short of the expected ten. "We agreed on ten," she stated, her tone flat. "That agreement was before the bridge toll increased," Aldric responded with a calculated smile that failed to reach his eyes. "Take it or leave it." As always, she chose to take it. The outer ring offered few alternatives, a fact Aldric understood all too well. Mirabel left the market, making her way through the narrow lanes beyond. The sun hung low in the sky, casting long shadows across the cobblestones. She tucked the pouch into her satchel and hastened her steps, determined to reach the bridge before nightfall.
