<nc-section data-title="Version 1" data-color="red"> As I approached the stables, a tall figure in gleaming armor stepped forward from the shadows. "Hail, young squire Frederick," boomed Sir Roland, his voice like rolling thunder. His grizzled beard framed a stern face marked by old scars, and his eyes twinkled with the wisdom of countless battles. "Dismount and tend to your steed. Your training begins at dawn." </nc-section> <nc-section data-title="Version 2" data-color="green"> The castle gates creaked open, leading me straight to the stables where hay bales towered like ancient monoliths. There, leaning against a post with arms crossed, stood Sir Roland, the local knight renowned for his unyielding honor. "Frederick, is it?" he called out warmly, clapping a gauntleted hand on my shoulder as I slid from Thunder's back. "Welcome to the heart of the kingdom. Let's see if you've the mettle for what's to come." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Reining in Thunder near the stables, I caught sight of Sir Roland emerging from the dim interior, his cloak billowing like dragon wings in the evening gust. "Squire Frederick," he greeted with a nod, his voice steady and commanding, eyes appraising me from helm to boot. "The castle is no place for the faint-hearted. Stable your horse—we've much to discuss before the stars claim the sky." </nc-section>
