<nc-section data-title="Chapter 1: The Arrival - Version 1" data-color="red"> As I dismounted near the bustling stables, a figure detached itself from the shadows cast by the great stone archway. He was a man of impressive build, his armor gleaming faintly in the twilight, a lion rampant crest emblazoned upon his surcoat. "Frederick, I presume?" His voice was deep, resonating with an authority that brooked no argument. "Sir Roland. Welcome to Oakhaven." He extended a gauntleted hand, his grip firm and unyielding. </nc-section> <nc-section data-title="Chapter 1: The Arrival - Version 2" data-color="green"> I led Thunder towards an empty stall, the scent of hay and horseflesh thick in the air. Before I could even begin to unbridle him, a calm, reassuring voice spoke from beside me. "Let me assist you, young squire." I turned to see a knight, his face kind but weathered, standing with a comfortable grace. His armor, though well-maintained, bore the marks of many battles. "Sir Roland," he introduced himself, offering a genuine smile. "You must be Frederick. A long ride, no doubt." </nc-section> <nc-section data-title="Chapter 1: The Arrival - Version 3" data-color="blue"> The moment Thunder's hooves clattered onto the stable yard's cobblestones, a sharp, authoritative voice cut through the stablehands' chatter. "Squire Frederick! About time you arrived." A tall, imposing knight, his polished plate armor reflecting the last rays of the sun, strode forward. He had an air of stern professionalism, a flicker of impatience in his piercing blue eyes. "I am Sir Roland, Knight of the King's Guard. Your training begins now, not tomorrow." </nc-section>
