<nc-section data-title="Version 1: The Knight's Welcome" data-color="red"> As I dismounted Thunder near the stables, a towering figure emerged from the shadows. Sir Roland, the local knight, clad in gleaming plate armor etched with the king's insignia, strode forward with a firm nod. "Young Frederick," he boomed, his voice like rolling thunder, "welcome to Castle Drakmoor. Your training begins at dawn—prove yourself worthy, or the dragons will claim you first." </nc-section> <nc-section data-title="Version 2: A Gruff Greeting" data-color="green"> Thunder snorted as I led him into the stables, the scent of hay and leather filling the air. There, leaning against a post with arms crossed, stood Sir Roland—battle-scarred and broad-shouldered, his eyes sharp as a hawk's. "Squire Frederick," he grunted, pushing off the wood, "ye've made it in one piece. Tend yer beast, then report to the armory. Laziness has no place here." </nc-section> <nc-section data-title="Version 3: Warmth in the Twilight" data-color="blue"> The castle gates creaked open just as I reached the stables, and from within stepped Sir Roland, his silver hair catching the dying light. With a warm smile beneath his mustache, he clasped my shoulder. "Frederick, lad, you've journeyed far. The Last Dragon's shadow looms, but fear not—under my guidance, you'll wield steel like legend itself. Come, stable your mount and share a tankard." </nc-section>
