<nc-section data-title="Version 1" data-color="red"> As Frederick reined in Thunder near the castle stables, a tall figure in polished armor strode forward with purpose. Sir Roland, the local knight renowned for his valor in the border skirmishes, raised a gauntleted hand in greeting. "Well met, young squire!" he boomed, his voice echoing off the wooden stalls. "I am Sir Roland. The king has spoken highly of your coming. Dismount and let us see to your steed—training begins at dawn." </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick led Thunder into the shadow of the stables just as Sir Roland emerged from the dim light within, wiping sweat from his brow after tending his own warhorse. The knight offered a firm nod and clasped Frederick's arm in welcome. "Ah, the new squire arrives at last. I am Sir Roland, charged with your early instruction. These stalls will be your second home now—stable your mount, and we'll speak of the path ahead over a shared meal." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Near the bustling stables, where grooms hurried with buckets of water and handfuls of hay, Sir Roland waited patiently for Frederick's arrival. As Thunder slowed to a halt, the knight stepped close, his cape catching the evening breeze. "Frederick, I presume? I am Sir Roland, knight of this keep. Welcome to your new life. Leave the horse to the stable hands and follow me—there is much to discuss before the feast tonight." </nc-section>
