<nc-section data-title="Version 1: A Stern Welcome" data-color="red"> As I dismounted near the stables, a towering figure emerged from the shadows. Sir Roland, his armor still bearing the dust of the training grounds, approached with heavy footsteps. His scarred face showed no warmth, only the hard scrutiny of a veteran warrior sizing up fresh meat. "So, you're the new squire," he said, his voice like gravel. "Your horse has more promise than you do, boy. We'll see if you last the week." He grabbed Thunder's reins from my hands without asking. "Stable him yourself. If you can't care for your mount, you're worthless to me." I swallowed hard, feeling the weight of his disappointment before I'd even begun. </nc-section> <nc-section data-title="Version 2: A Warm Greeting" data-color="green"> The stable doors swung open, and out stepped Sir Roland, a broad smile crossing his weathered face. Unlike the grim knights I'd imagined, he moved with an easy grace, his hand extended in welcome. "Frederick! Your father wrote of your arrival," he said warmly, clasping my shoulder as I dismounted. "And this must be Thunder—a fine beast indeed." He stroked the stallion's neck with practiced gentleness. "You've had a long journey. Let's get your horse settled, and then we'll find you a hot meal and a bed. Tomorrow is soon enough for the hard work to begin." His kindness eased the knots of anxiety in my chest. </nc-section> <nc-section data-title="Version 3: A Mysterious Encounter" data-color="blue"> I led Thunder toward the stables when a figure stepped into my path. Sir Roland stood motionless, his eyes fixed not on me, but on something beyond—or perhaps within. His hand rested on the pommel of his sword, and for a moment, I wondered if I should draw my own blade. "You carry the mark," he whispered, his voice barely audible. "Just like the prophecy foretold." His gaze finally met mine, and I saw something I didn't expect: fear. "Tell me, boy—have you dreamed of fire? Of scales and ancient voices calling your name?" I stood frozen, unsure how he could possibly know about the dreams that had haunted me for months. </nc-section>
