<nc-section data-title="Version 1: A Warm Welcome" data-color="red"> As I reined in Thunder near the stables, a tall knight with a weathered face and a neatly trimmed beard strode forward. "Welcome, young squire Frederick," boomed Sir Roland, his voice carrying the authority of years on the battlefield. He clasped my forearm firmly, his grip like iron. "I've heard tales of your courage from the village. The castle is honored by your presence." </nc-section> <nc-section data-title="Version 2: A Stern Greeting" data-color="green"> Dismounting amidst the scent of hay and horses, I was approached by Sir Roland, the local knight, his armor glinting in the fading light. His eyes narrowed appraisingly as he halted before me. "Squire Frederick, is it? Prove your mettle here, lad," he said gruffly, offering a gauntleted hand that spoke more of challenge than cheer. "The stables are no place for weaklings." </nc-section> <nc-section data-title="Version 3: A Mysterious Encounter" data-color="blue"> Thunder nickered softly as I led him toward the stables, where a figure emerged from the shadows—Sir Roland, cloaked in twilight. "Frederick," he murmured, his voice a low rumble like distant thunder, extending a hand scarred by ancient battles. "The winds whisper of your destiny. Come, let us speak of dragons and forgotten prophecies while your steed is tended." </nc-section>
