<nc-section data-title="Chapter 1: The Arrival" data-color="red"> As I dismounted near the stables, a tall, imposing figure in polished plate armor approached. "Welcome, Frederick," Sir Roland rumbled, his voice like distant thunder. "We've been expecting you." He extended a gauntleted hand, his grip surprisingly firm. "I trust your journey was uneventful?" I nodded, a little awestruck. His presence was formidable, his eyes sharp and assessing. </nc-section> <nc-section data-title="Chapter 1: The Arrival" data-color="green"> I led Thunder into the stable yard, the scent of hay and horses filling the air. A man, broad-shouldered and with a kind, weathered face, emerged from the stable doors. He wore a simple tunic over his chainmail, a sword hilt peeking above his hip. "Frederick, I presume?" he said with a warm smile. "Sir Roland, at your service. Let me help you with your steed." He took Thunder's reins with an easy familiarity, his movements efficient and strong. </nc-section> <nc-section data-title="Chapter 1: The Arrival" data-color="blue"> Just as I was about to secure Thunder, a shadow fell over me. I turned to see a knight, easily a head taller than me, standing silently by the stable entrance. His armor gleamed, and a long, dark cloak billowed slightly behind him. "Frederick," he stated, his voice a low, gravelly tone, more a pronouncement than a greeting. "I am Sir Roland. The stable master will see to your horse. You will follow me." There was an undeniable authority in his words, leaving no room for argument. </nc-section>
