<nc-section data-title="Version 1: The Greeting of Sir Roland" data-color="red"> As I approached the stables, a tall figure stepped forward, his armor gleaming in the fading sunlight. Sir Roland, the kingdom's most renowned knight, clasped a firm hand on my shoulder. "Welcome, young squire," he said with a commanding voice. "The path of a knight is arduous, but I see potential in you. Follow me; your training begins at dawn." </nc-section> <nc-section data-title="Version 2: The Warm Welcome" data-color="green"> Near the stables, Sir Roland awaited, his kind eyes crinkling into a gentle smile. "Ah, you must be Frederick," he said warmly, extending a gauntleted hand. "I've heard of your arrival. Come, let me show you around. There's much to learn, and I’ll be here to guide you every step of the way." </nc-section> <nc-section data-title="Version 3: The stern encounter" data-color="blue"> Standing by the stables, Sir Roland's imposing figure observed me silently before speaking. "Hail, squire," he said sharply, his tone brooking no nonsense. "You are expected, but heed my words: discipline and strength are what will forge your future. Follow me, and don’t disappoint the realm."
