```html <nc-section data-title="Version 1: Shadows of Welcome" data-color="red"> As Frederick reined in Thunder near the stables, the scent of hay and horseflesh thick in the evening air, a towering figure in dented armor stepped from the shadows. Sir Roland, the local knight, fixed him with a hard gaze, his scarred face barely visible beneath a gorget. "You must be the new squire," he growled, voice like grinding stone. "The Last Dragon's shadow grows long over this castle. Train hard, boy, or you'll feed the beasts before the fortnight ends." Frederick dismounted, heart pounding, as Roland's gauntleted hand clapped his shoulder like a blow meant to test his mettle. </nc-section> <nc-section data-title="Version 2: A Knight's Steady Hand" data-color="green"> Thunder's hooves clattered to a halt by the stable doors, where the warm light of lanterns spilled out onto the cobbles. Sir Roland, the local knight, approached with a steady stride, his polished half-plate gleaming softly and a welcoming smile creasing his weathered features. "Frederick, is it? Welcome to the castle," he said, taking the reins with sure hands. "I've heard of your coming. Let's get this fine stallion settled, and then we'll speak of your training under the banners of the realm. The Chronicles of the Last Dragon begin anew with each squire's first step." </nc-section> <nc-section data-title="Version 3: Veiled Portents" data-color="blue"> Near the stables, as the last light faded and bats wheeled overhead, Frederick swung down from Thunder to find Sir Roland waiting, cloaked in midnight blue. The local knight inclined his head gravely, eyes reflecting the distant torches. "Young Frederick," he murmured, voice low as a dragon's distant rumble. "The castle awakens to your arrival. Yet listen well—rumors stir of scales in the hills. Come, I will show you the way and arm you with truths your masters may yet withhold." Side by side they walked into the lamplight, destinies intertwining. </nc-section> ```
