<nc-section data-title="Version 1: Greeting at the Stables" data-color="red"> As I dismounted Thunder near the stables, a towering figure approached, clad in gleaming plate armor etched with the kingdom's roaring lion emblem. "Welcome, young squire Frederick," boomed Sir Roland, his voice like rolling thunder. His grizzled beard framed a face scarred from countless battles, and his eyes sparkled with the wisdom of a seasoned knight. He clasped my shoulder firmly. "You've arrived just in time. The king seeks brave hearts for the trials ahead." </nc-section> <nc-section data-title="Version 2: The Knight's Welcome" data-color="green"> Dismounting amidst the earthy scent of hay and horses, I turned to find Sir Roland striding from the stable shadows. His chainmail clinked softly, and a warm smile softened his weathered features. "Frederick, lad! We've been expecting you," he said, extending a gauntleted hand. The local knight's reputation for fairness preceded him, and in that moment, I felt the weight of destiny settle upon my shoulders like a well-fitted cloak. </nc-section> <nc-section data-title="Version 3: Encounter by the Stables" data-color="blue"> Thunder nickered softly as I led him into the stables, where Sir Roland awaited, polishing his sword by lantern light. The knight rose, his broad frame filling the doorway. "Hail, Squire Frederick," he greeted with a nod, his voice steady and commanding. Legends whispered of his dragon-slaying exploits, and up close, the fire in his gaze confirmed every tale. "Come, boy. Your training—and our world's fate—begins now." </nc-section>
