<nc-section data-title="The Stern Welcome" data-color="red"> As I dismounted, the heavy thud of plate armor announced a presence before I even turned. Sir Roland stood in the shadow of the stable archway, his face a map of jagged scars and stern lines. He didn't offer a smile, only a narrowed gaze that raked over my travel-worn tunic. "You're late, boy," he rumbled, his voice like grinding stones. "The dragons don't wait for squires to finish their afternoon rides, and neither do I. Unpack your gear and get to the stalls; if a single horse is groomed poorly, you'll be sleeping in the hay with them." </nc-section> <nc-section data-title="A Mentor's Assessment" data-color="green"> I had barely untethered my horse when a hand, calloused and thick with years of swordplay, rested firmly on my shoulder. Sir Roland emerged from the gloom of the stables, his expression unreadable but his eyes dancing with a hidden fire. "Thunder carries himself well," the knight observed, tilting his head toward my mount. "A horse tells you everything you need to know about the rider's heart. You’ve treated him with care, Frederick. Let us hope you bring that same patience to the blade. Follow me—the armory is cold this time of night, but the steel is warm enough." </nc-section> <nc-section data-title="The Burden of Training" data-color="blue"> "Frederick," a voice called out, resonating with a metallic resonance that made the air feel thin. Sir Roland leaned against a wooden pillar, cleaning a long, silver-hilted dagger with a scrap of cloth. I froze, suddenly feeling the weight of the crest on my tunic. He stepped forward into the dying light, his eyes assessing me with a quiet, terrifying intensity. "Many have come to these stables seeking glory, but the Last Dragon casts a long shadow over those who dream of fame. Tell me, lad—are you here for a title, or are you here to endure the fire?" </nc-section>
