<nc-section data-title="Version 1" data-color="red"> As I reined in Thunder near the stables, a tall knight in gleaming armor strode forward, his boots crunching on the gravel. "Welcome, young squire Frederick," boomed Sir Roland, his voice warm and commanding. He clapped a gauntleted hand on my shoulder, eyes twinkling with mirth. "You've made good time. Come, let us stable your beast and begin your initiation into the ways of the blade." </nc-section> <nc-section data-title="Version 2" data-color="green"> Dismounting amidst the whinnying horses in the stables, I was approached by Sir Roland, the local knight renowned for his valor in the border skirmishes. His face was weathered, scarred from battles past, yet his greeting carried a note of gruff approval. "Squire Frederick, eh? Prompt as the dawn. Hand me those reins—Thunder looks like he could use a rubdown after that ride. Report to the armory at first light." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Thunder's hooves had barely stilled by the stable doors when Sir Roland emerged from the shadows, his cloak billowing like dragon wings. The knight's piercing gaze assessed me in an instant. "Frederick, the last hope of the squires' line," he said softly, extending a hand in formal greeting. "The castle senses your arrival. Stable your mount swiftly; whispers of the Last Dragon stir even now." </nc-section>
