<nc-section data-title="Version 1: A Stern Welcome" data-color="red"> I dismounted, my boots sinking into the damp straw near the stable doors. Before I could even soothe Thunder's nervous breathing, a shadow fell over us. Sir Roland stood there, his armor scarred from battles I had only read about in leather-bound volumes. He didn't offer a hand, nor did his stern countenance soften. "You're late, boy," he rumbled, his voice like grinding millstones. "In my garrison, procrastination is a swifter killer than a rebel's blade. Rub down your beast, then report to the yard. Your training begins before the moon reaches its crest." </nc-section> <nc-section data-title="Version 2: An Warm Reception" data-color="green"> As Thunder came to a halt by the bustling stables, a hearty laugh echoed from the shadows of the wooden eaves. Sir Roland stepped into the fading sunlight, tossing a crisp apple to my weary mount. "Ah, the young Frederick!" he boomed, clapping a heavy, gauntleted hand onto my shoulder. "We have been expecting you. Fear not the solemn walls of this great keep, lad. By the time we are through with you, you'll call these stone ramparts home. Come, let the stablehands tend to your horse, and let us get some hot broth in your belly." </nc-section> <nc-section data-title="Version 3: A Calculating Appraisal" data-color="blue"> The smell of wet hay and leather filled my senses as I led Thunder toward the hitching post. Standing nearby, quietly observing my approach with keen, slate-gray eyes, was Sir Roland. He did not move immediately, instead watching how I handled the stallion, measuring my posture, my grip on the reins, and the exhaustion etched into my young face. "You handle the beast well enough," he spoke softly, stepping forward with a slow, deliberate grace. "But riding a horse is the easiest lesson you will learn here, Frederick. Let us see if your spirit is as sturdy as your mount." </nc-section>
