<nc-section data-title="The Stern Welcome" data-color="red"> As I dismounted near the stables, the smell of hay and old leather filling my senses, a shadow fell across the cobblestones. Sir Roland stood there, his scarred hand resting on the pommel of a broadsword. He didn't offer a smile, only a sharp, appraising look that seemed to weigh my very soul. "You’re late, boy," he growled, his voice like grinding stones. "Thunder may be fast, but in this castle, discipline is faster. Stable your mount and report to the armory; your training begins before the sun fully retreats." </nc-section> <nc-section data-title="A Knight's Kindness" data-color="green"> I was still patting Thunder’s neck when a boisterous laugh echoed from the stable doors. Sir Roland stepped out, tossing a crisp apple to my horse. "Fine beast you have there, Frederick," the knight said, his eyes crinkling with genuine warmth. He placed a heavy, encouraging hand on my shoulder, his armor clinking softly. "The journey from the southern vales is long, but your real journey starts tonight. Rest your legs, take a meal, and tomorrow we shall see if you have the heart of a dragon-slayer." </nc-section> <nc-section data-title="Professional Duty" data-color="blue"> The gates had barely rattled shut behind me when Sir Roland approached, checking a scroll of parchment. He was a man of precise movements, his tabard spotless despite the dust of the training grounds. "Squire Frederick, I presume," he stated, more of a fact than a question. He gestured for a stable hand to take Thunder's reins. "I am Sir Roland. You will find that life at the castle favors the diligent and punishes the distracted. Follow me; there are protocols to learn and a lineage to uphold." </nc-section>
