<nc-section data-title="Alternate Continuation: Version 1" data-color="red"> As I dismounted Thunder near the stables, the earthy scent of hay and horse filled the air. A tall figure approached, his armor gleaming in the fading light. It was Sir Roland, the local knight, his face weathered but kind. "Welcome, young Frederick," he boomed with a hearty laugh, clapping me on the shoulder. "I've heard much about your potential. Let's get you settled—the real training begins at dawn." </nc-section> <nc-section data-title="Alternate Continuation: Version 2" data-color="green"> Reining in Thunder at the edge of the stables, I felt the weight of the journey in my bones. The castle's shadows loomed longer now, and from them emerged Sir Roland, his emerald cloak billowing like forest leaves. "Frederick, the squire," he said with a nod, his voice steady and warm like a summer breeze. "You've arrived just in time. Come, stable your horse, and I'll show you to your quarters. The path of a knight is one of growth and valor." </nc-section> <nc-section data-title="Alternate Continuation: Version 3" data-color="blue"> I guided Thunder into the stables as the twilight deepened, the castle's stones whispering secrets in the wind. A knight stepped forward from the dim light—Sir Roland, his eyes sharp as a hawk's under a hood of deep blue. "Ah, Frederick," he murmured, his tone laced with intrigue. "The stars align for your arrival. Greet the night with caution; not all shadows here are friendly. Follow me, and we'll speak of dragons and destinies." </nc-section>
