<nc-section data-title="Sir Roland's Stern Welcome (Version 1)" data-color="red"> As I dismounted in the shadow of the great stone stables, the heavy scent of straw and leather filled the air. A towering figure stepped out from the gloom of the carriage house. It was Sir Roland. His armor was scarred from head to toe, a testament to a dozen brutal campaigns, and his eyes held the cold, unyielding gray of a winter sky. He didn't offer a hand, nor did he smile. He merely looked down at me, his voice like grinding stones. "So, this is the boy they sent. I hope your spine is stronger than your soft hands, Frederick. Out here, weak men are food for the crows. Stable your horse, then find me in the courtyard. Do not make me wait." </nc-section> <nc-section data-title="A Warm Reception (Version 2)" data-color="green"> I slid down from Thunder's saddle, my knees slightly shaky after the long journey. Before I could even grab my travel pack, a booming laugh echoed from the stable doorway. Out strode Sir Roland, his broad shoulders draped in a rich forest-green cloak. His weathered face broke into a wide, crinkly-eyed grin beneath a thick graying beard. "Lads!" he called out to the nearby stablehands. "Get this fine beast some fresh oats and water!" He marched over to me, clapping a heavy, calloused hand onto my shoulder. "Welcome to the Keep, Frederick! Your father spoke highly of your courage. We'll make a true knight of you yet. Come, let's get some warm broth in your belly." </nc-section> <nc-section data-title="The Knight's Evaluation (Version 3)" data-color="blue"> The stables were a hive of quiet activity, but a sudden silence fell over the grooms as Sir Roland approached. He was a man of precise movements, dressed in a simple, well-kept tunic of midnight blue. He stood silently for a long moment, watching how I handled Thunder's reins and how I carried myself. His analytical gaze felt like a physical weight. Finally, he gave a single, slow nod of approval. "You have a gentle hand with the beast, Frederick. That shows discipline. Discipline is the foundation of everything we do here." He gestured toward the iron-studded doors of the armory. "Walk with me. It is time we discuss the expectations of your training." </nc-section>
