Here are 3 alternate prose sections that continue the story: <nc-section data-title="Version 1: Sir Roland's Greeting" data-color="red"> As I dismounted Thunder near the stables, a broad-shouldered knight strode towards me, his armor gleaming in the dying light of the sun. His face was weathered, marked by years of battle, yet his eyes held a warmth that put me at ease. "You must be Frederick," he said, his voice deep and commanding. "I am Sir Roland, knight of the realm." He extended a gauntleted hand, and I shook it firmly, trying not to betray my nervousness. "I've heard good things about you, boy. Let us hope they are true." He turned on his heel and gestured for me to follow, leading me into the dimly lit stables where the smell of hay and horse filled my lungs. </nc-section> <nc-section data-title="Version 2: Sir Roland's Greeting" data-color="green"> The stables were alive with the sounds of horses when a gruff voice called out from the shadows. "Oi! You there — you Frederick?" A stout knight emerged, wiping his hands on a rough cloth, his armor half-buckled and his grey beard unkempt. He looked nothing like the heroic knights of the stories my mother used to tell me. "I am, Sir Roland," I replied cautiously. He squinted at me for a long moment, then broke into a wide, gap-toothed grin. "Good. You're late, but you're here." He clapped me hard on the back, nearly sending me sprawling into the mud. "Come, lad. There's much work to be done before you even think about touching a sword." </nc-section> <nc-section data-title="Version 3: Sir Roland's Greeting" data-color="blue"> I had barely tied Thunder to the post when I felt a presence behind me — silent, deliberate, like a shadow given form. I turned to find a tall, lean knight watching me with sharp, calculating eyes. A long scar ran from his left temple to his jaw, a pale reminder of battles long past. "Frederick," he said. It was not a question. "I am Sir Roland." His gaze swept over me slowly, assessing every inch of me with unsettling precision. "You are younger than I expected," he murmured, almost to himself. Then his eyes met mine, cold and serious. "The dragon has been seen again, boy. In the eastern mountains." He paused, letting the words sink into the cool evening air. "Your training begins at dawn. Do not be late." </nc-section>
