<nc-section data-title="Version 1: A Stern Welcome" data-color="red"> As I dismounted in the shadow of the massive stone stables, the heavy scent of straw and damp earth filled the air. Out of the gloom stepped Sir Roland. He was a mountain of a man, his armor scarred by battle and his face etched with a permanent scuff of grim determination. He didn't offer a hand, nor did he smile. Instead, his cold grey eyes swept over me, assessing my posture, my travel-worn clothes, and the tremor in my hands. "So, the Council sends me a boy," he rumbled, his voice like grinding stones. "Tie up your mount, squire. In my ward, we do not rest until the steel is polished and the horses are fed. Move." </nc-section> <nc-section data-title="Version 2: A Warm Reception" data-color="green"> I slid down from Thunder's saddle, my boots sinking slightly into the soft, clean hay scattering the courtyard. A hearty laugh echoed from the stable doors, and Sir Roland emerged, wiping grease from his hands with a rag. He wore no armor, only a simple tunic, but his broad shoulders left no doubt of his martial prowess. "Ah, the new squire! Frederick, isn't it?" he boomed, clapping a heavy, warm hand onto my shoulder. "Welcome to the keep, lad. Don't look so terrified—we don't bite here, though the training might leave a bruise or two. Let’s get your stallion settled, and then we'll find you some hot supper." </nc-section> <nc-section data-title="Version 3: An Evaluative Encounter" data-color="blue"> The stables were a hive of quiet activity, but the commotion seemed to part around one man. Sir Roland stood watching my approach, leaning casually against a wooden post, his arms crossed over a finely embroidered doublet. As I led Thunder closer, his sharp, calculating gaze flicked from my grip on the reins to the way I carried myself. "You ride well, Frederick," he noted, his voice calm, measured, and impossible to read. "But riding a horse is the easiest part of what you will learn here. Hand your stallion to the stable boy. Let us walk, and we shall see if your mind is as steady as your saddle." </nc-section>
