<nc-section data-title="Version 1: The Knight's Welcome" data-color="red"> As Frederick dismounted Thunder near the ancient stables, a towering figure emerged from the shadows of the stone archway. Sir Roland, the local knight whose legends of valor had reached even the farthest villages, strode forward with purpose. His armor gleamed in the fading sunlight, and his weathered face broke into a stern yet welcoming smile. "Young Frederick," he boomed, his voice carrying the weight of countless battles. "The castle has awaited your arrival. Come, let me show you where true warriors are forged." </nc-section> <nc-section data-title="Version 2: Shadows of Expectation" data-color="green"> The stables smelled of hay and leather as Frederick led Thunder inside, his heart pounding with nervous anticipation. Before he could properly secure the reins, a broad-shouldered man in polished plate armor approached from the adjacent courtyard. It was Sir Roland, his grizzled beard and piercing eyes marking him as the castle's most respected knight. "So this is the squire they've sent me," Roland said, his tone measured but not unkind. He placed a heavy hand on Frederick's shoulder. "Training begins at dawn tomorrow. But first, tell me—do you possess the fire in your blood that the old tales speak of?" </nc-section> <nc-section data-title="Version 3: An Unexpected Encounter" data-color="blue"> Thunder whinnied softly as they reached the stable yard, and Frederick patted the stallion's neck gratefully after their long journey. From behind a stack of wooden barrels stepped Sir Roland, the renowned local knight, wiping his hands on a cloth after tending to his own warhorse. His expression softened upon seeing the young squire. "Frederick, is it?" he asked, extending a calloused hand in greeting. "The castle walls have grown quiet of late. Perhaps your arrival signals the beginning of something greater than we know. Walk with me, lad, and I'll tell you what it truly means to serve under the banner of the Last Dragon." </nc-section>
