<nc-section data-title="Version 1: The Stern Greeting" data-color="red"> The clatter of Thunder's hooves faded to a steady clip-clop as I guided him into the castle's expansive stable yard. A hulking figure stood silhouetted against the lantern light spilling from the stable doors. As I dismounted, the figure stepped forward, revealing a man clad in dented plate armor, a grim set to his jaw. "You must be the new whelp," he rumbled. "I am Sir Roland." His voice was a low growl, devoid of warmth. He didn't offer a hand. Instead, he pointed a gauntleted finger at Thunder. "Your horse is lathered. A knight learns to pace his mount. First lesson: see to his care before your own. There's a hayrack and a clean stall. If you cannot manage the stable, you cannot manage a sword." </nc-section> <nc-section data-title="Version 2: The Warm Welcome" data-color="green"> I dismounted, my legs aching pleasantly from the long ride. A booming laugh echoed from across the yard. "Ho there! The young scholar arrives!" Sir Roland, his armor polished to a blinding shine even in the dusk, strode toward me with a gait that was surprisingly light for such a large man. His face was open and friendly, a broad grin splitting his thick beard. He clasped my shoulder in a grip that was firm, yet not crushing. "Frederick, is it? No, don't bother with formalities. I'm Sir Roland. We have no time for stiff bows and 'my lords' here. I'm more interested in how you held your seat on that brute of yours." He winked. "Looked like a good ride. Come, you must be starving. I've saved you a spot at the hearth." </nc-section> <nc-section data-title="Version 3: The Observant Mentor" data-color="blue"> The transition from the field to the stable yard was sudden, the smell of hay and horse replacing the scent of wild grass. I found myself leading Thunder toward a man who stood motionless, leaning against a post. He was not as large as I had imagined a knight would be. Sir Roland was lean, wiry, and his eyes, the color of storm clouds, missed nothing. "Frederick," he said. It wasn't a question. He looked me over, from the worn leather of my saddle to the dust on my boots. A slow, assessing nod. "You didn't push your horse beyond his rhythm. That shows a level of sense most lack." He gestured with his chin toward a small anvil set by the stable wall. "I saw you ride in. Your left hand dropped to your belt twice as you looked around. You have a nervous habit, but you are also observant. Tonight, we will take a walk along the battlements. Tell me what you see. A knight's first duty is to know his ground." </nc-section>
