<nc-section data-title="Meeting Sir Roland: The Veteran's Test" data-color="red"> As I dismounted near the cobblestone courtyard of the stables, the heavy thud of iron-shod boots echoed across the yard. Out from the gloom stepped Sir Roland. He was a mountain of a man, clad in worn chainmail that bore the dents and scars of a hundred skirmishes. His piercing gray eyes swept over Thunder before settling hard upon me, measuring every inch of my posture. "So, you're the new blood," Roland grunted, his voice like grinding millstones. He didn't offer a hand, only crossed his thick arms over a faded heraldic crest. "The ride was easy, boy. The road ahead won't be. Unsaddle your beast, scrape the muck from his hooves, and report to the armory before the candles gutter out. Let’s see if your spine is made of iron or brittle reed." </nc-section> <nc-section data-title="Meeting Sir Roland: A Warm Welcome" data-color="green"> Guiding Thunder beneath the wooden archway of the stables, I smelled sweet hay and fresh leather. A hearty laugh broke the evening calm, and a tall knight stepped forward with an open smile creasing his weathered, bearded face. Sir Roland set aside a bristle brush and wiped his calloused hands on his tunic as he approached. "Welcome to the fold, Frederick!" he called out warmly, clapping a heavy, reassuring hand onto my shoulder. "Your father spoke often of your spirit in his letters, though he failed to mention you rode such a magnificent beast. Come, let’s get your mount a warm stall and some grain. There will be plenty of sweat and steel on the morrow, but tonight, you are among friends." </nc-section> <nc-section data-title="Meeting Sir Roland: Shadows and Whispers" data-color="blue"> The stables were eerily quiet in the twilight, save for the nervous shifting of the horses in their stalls. Standing by the lantern light was Sir Roland, gazing up at the shadowed battlements rather than at my arrival. His silver-streaked hair fell loose across his shoulders, and at his hip hung a sword whose hilt was carved in the likeness of a coiled serpent. He turned slowly, his expression haunted by thoughts far away from castle politics. "You arrive in an ill-omened season, Frederick," Roland spoke softly, his voice barely rising above the evening draft. "The skies to the north grow restless again, and the old fires are rekindling in the crags. Tend to your horse swiftly, squire. The realm has little time to spare for gentle lessons, and tomorrow our vigils begin in earnest." </nc-section>
