<nc-section data-title="Version 1: Greeting at the Stables" data-color="red"> As I reined in Thunder near the stables, a tall knight with a weathered face and a gleaming breastplate strode forward. "Welcome, young squire Frederick," boomed Sir Roland, his voice rich and commanding yet laced with genuine warmth. He clasped my forearm firmly, his grip like iron forged in battle. "The castle has awaited your arrival. Come, let us stable your steed and speak of the trials ahead." </nc-section> <nc-section data-title="Version 2: Greeting at the Stables" data-color="green"> Dismounting amidst the earthy scent of hay and horses, I found myself face-to-face with Sir Roland, the local knight renowned for his valor in the border skirmishes. He approached with measured steps, his cloak embroidered with the king's stag emblem billowing slightly. "Squire Frederick," he said formally, offering a gauntleted hand, "you ride with purpose. The stables await your mount, and I, your first lesson in duty." </nc-section> <nc-section data-title="Version 3: Greeting at the Stables" data-color="blue"> Thunder's hooves clattered to a halt by the stables as shadows lengthened across the courtyard. From the dim archway emerged Sir Roland, his eyes sharp beneath a furrowed brow, armor scarred from forgotten wars. "Frederick," he greeted in a low, gravelly tone that sent a shiver down my spine, extending a hand that bore the weight of ancient oaths. "The winds whisper of your coming. Tend to your horse, lad—greater shadows stir beyond these walls." </nc-section>
