<nc-section data-title="Chapter 1: A Knight's Welcome" data-color="red"> As I dismounted near the stables, a broad-shouldered figure emerged from the shadows of the wooden beams. His armor bore the emblem of a silver falcon, and his weathered face broke into a warm smile. "You must be young Frederick," he said, extending a gauntleted hand. "I am Sir Roland. Word of your arrival preceded you." Thunder snorted and stamped, sensing the presence of the seasoned warrior. Sir Roland chuckled, running a hand along the horse's mane. "A fine steed. Come, let's get him settled before we speak of your training." </nc-section> <nc-section data-title="Chapter 1: The Stablemaster's Greeting" data-color="green"> The stable boys scattered as I approached, whispering amongst themselves. Then I saw him—Sir Roland, unmistakable in his ceremonial armor even in the fading light. He had been leaning against a wooden post, watching my approach with keen interest. "So the new squire arrives at last," he called out, his voice carrying the weight of authority tempered with kindness. "I've trained many young hands, but few arrive with such fire in their eyes." He gestured to the stable entrance. "Tend to your horse first. A knight who neglects his mount neglects his honor. Then you and I shall discuss what lies ahead." </nc-section> <nc-section data-title="Chapter 1: An Unexpected Welcome" data-color="blue"> I hadn't expected anyone to be waiting, but as Thunder's hooves clattered against the cobblestones near the stables, a tall man stepped into view, his silver breastplate catching the last rays of sunlight. "Sir Roland, at your service," he announced with a slight bow, though his eyes carried an appraising glint. "The castellan mentioned a new squire would arrive today, though I confess I expected someone... older." He laughed heartily, clapping a hand on my shoulder. "No matter. Age matters little if the heart is willing. Let's see to your horse, and then I'll show you where you'll be sleeping tonight." </nc-section>
