<nc-section data-title="A Stern Welcome" data-color="red"> I reined in Thunder just inside the castle gates, the clatter of hooves echoing off the cobblestones. Before I could dismount, a knight in gleaming plate armor stepped from the shadow of the stables—Sir Roland, the master-at-arms. His eyes were hard as flint, and a scar ran from brow to jaw. "You're late, squire," he barked, his voice cutting through the evening air. "Stow your horse and report to the training yard. I don't tolerate tardiness." I swallowed, suddenly aware that the stories of his strictness were not exaggerated. </nc-section> <nc-section data-title="A Warm Greeting" data-color="green"> As I led Thunder toward the stables, a cheerful voice rang out. "You must be Frederick!" A knight with a kindly face and a neatly trimmed beard strode forward, his armor catching the last rays of sunlight. It was Sir Roland, the very knight I had admired from the tapestries. He clapped a hand on my shoulder. "Welcome to the castle, lad. The horses are well cared for here—let me show you to the stalls. There's a hot meal waiting after, and we'll begin your training in the morning." I felt my nervousness melt away under his easy smile. </nc-section> <nc-section data-title="A Mysterious Encounter" data-color="blue"> The stables were quiet, save for the soft nickering of horses. As I dismounted, I noticed a tall figure leaning against a stall door, half-shrouded in twilight. It was Sir Roland, though he wore no armor now, only a dark cloak. He studied me with an unreadable expression. "So you're the new squire," he said softly, his voice like wind through autumn leaves. "I trust you're not afraid of legends? This castle has more secrets than you can imagine." He turned and beckoned me to follow, disappearing into the dimly lit stable. A shiver ran down my spine, but curiosity drove me onward. </nc-section>
