<nc-section data-title="Version 1: The Knight's Welcome" data-color="red"> As I guided Thunder through the castle gates and toward the stables, the last rays of sunset painted the stone buildings in hues of amber and rose. I dismounted, my legs stiff from the long ride, and began to loosen the stallion's saddle. Heavy footsteps approached from behind. A broad-shouldered knight in polished plate armor stepped into the lantern light, his crimson cloak billowing slightly. "You must be Frederick, the new squire," he said, his voice deep yet kind. "I am Sir Roland, keeper of the stables and trainer of fledgling warriors. You've chosen a fine mount—few arrive with such spirit in both horse and rider." </nc-section> <nc-section data-title="Version 2: Shadows of Expectation" data-color="green"> The castle gates creaked shut behind me as Thunder carried me the final stretch to the stables. The evening air carried the scent of hay and oiled leather. I slid from the saddle, patting the horse's sweat-dampened neck, when a figure emerged from the stable doorway holding a flickering torch. Sir Roland's face was weathered and serious, his green surcoat embroidered with the kingdom's dragon emblem. "Squire Frederick," he greeted me gruffly, though not unkindly. "You've kept good time. Many squires arrive late and already defeated. Come, let us see if that fire in your eyes matches the strength needed to serve the Last Dragon's legacy." </nc-section> <nc-section data-title="Version 3: The Knowing Glance" data-color="blue"> Thunder snorted and slowed as we reached the shadowed eaves of the stables, the banners above now dark against the twilight sky. My boots hit the packed earth, and I reached for the bridle when a calm voice called out from the gloom. Sir Roland strode forward, his blue cloak seeming to absorb the remaining light, a silver pin shaped like a coiled dragon at his throat. "Frederick," he said, studying me with eyes that seemed older than the castle stones themselves. "The local knight, at your service. The wind told me a squire of uncommon blood would arrive today. Your horse senses it too, I think. Few beasts carry themselves with such pride near these walls." </nc-section>
