<nc-section data-title="Version 1: The Knight's Salute" data-color="red"> I dismounted Thunder near the stables, my boots sinking into the soft earth. From the shadows of the stable door emerged a towering figure clad in silver armor. Sir Roland, the local knight, was a legend in our village, though I had never seen him in person. His beard was thick and gray, and a long scar ran down his left cheek. He stopped a few paces from me and drew his sword. I froze, my heart hammering against my ribs. But he did not strike. Instead, he planted the blade point-down in the dirt and rested both hands upon the pommel. "So," he rumbled, his voice like stones grinding together, "you are the boy they sent. Frederick, is it?" I nodded, unable to find my voice. He looked me up and down with the cold, measuring gaze of a man who had seen a hundred squires come and go. "Well then, Frederick. Let us see if you last the week." </nc-section> <nc-section data-title="Version 2: A Warm Welcome" data-color="green"> The stable boy took Thunder's reins with a friendly nod, and I was just brushing the dust from my tunic when a voice called out behind me. "You there! The new squire!" I turned to see a man striding toward me, and I knew at once it was Sir Roland, though he looked nothing like the stern warrior the village tales had led me to expect. He was tall, yes, and broad across the shoulders, but his face was kind, creased with laugh lines rather than battle scars. His armor was plain but well-kept, and he smelled faintly of horses and hay. "Frederick, isn't it?" he said, offering a hand. "I'm Roland. Welcome to the castle. I hope your ride was fair." I shook his hand, speechless at the warmth of his greeting. "Come along," he said, clapping me on the shoulder. "Supper's on the table, and I imagine you're famished." </nc-section> <nc-section data-title="Version 3: The Shadow at the Stable" data-color="blue"> I had barely finished tethering Thunder when I felt a cold presence behind me. I turned slowly. Sir Roland stood at the edge of the stable, half-hidden in the deepening dusk. He wore no armor, only a dark cloak that seemed to swallow the little light that remained. His pale eyes studied me without blinking. "You came alone," he said. It was not a question. "Yes, sir," I answered, though my voice sounded small. He stepped closer, and I noticed the way the horses grew quiet in his presence, as if they too were afraid. "Good," he murmured. "The roads have not been kind of late. There have been things moving in the woods that ought not to be moving." He glanced toward the black treeline beyond the castle walls. "Come, Frederick. We have much to speak of before the sun is fully gone." </nc-section>
