<nc-section data-title="Version 1: The Knight's Welcome" data-color="red"> As I reined in Thunder near the stables, a tall figure in gleaming armor strode forward. Sir Roland, the local knight renowned for his valor in the border skirmishes, extended a gauntleted hand. "Young Frederick, you've made good time," he boomed with a hearty laugh, clapping me on the shoulder as I dismounted. "The castle's been awaiting a squire with fire in his eyes like yours. Come, stable your mount and let's get you settled." </nc-section> <nc-section data-title="Version 2: A Formal Greeting" data-color="green"> Dismounting amidst the scent of hay and horseflesh by the stables, I was approached by Sir Roland, his tabard emblazoned with the king's stag. He bowed slightly, his voice steady and commanding. "Squire Frederick, welcome to these halls. I am Sir Roland, your mentor in the arts of knighthood. Hand your reins to the stableboy and follow me—we begin your training at dawn." </nc-section> <nc-section data-title="Version 3: Shadows of Prophecy" data-color="blue"> Thunder's hooves had barely stilled near the stables when Sir Roland emerged from the twilight shadows, his eyes sharp as a falcon's. "Frederick," he said gravely, gripping my arm with iron strength, "the stars whispered of your coming. I am Sir Roland, guardian of ancient oaths. Stable your beast swiftly; there are tidings of the Last Dragon that demand your ear before the night deepens." </nc-section>
