<nc-section data-title="Version 1: The Knight's Welcome" data-color="red"> As I reined in Thunder before the grand castle gates, a figure strode forth from the shadow of the stables—a towering knight clad in gleaming plate armor, his cloak emblazoned with the roaring lion of Eldoria. "Hail, young squire Frederick!" boomed Sir Roland, his voice like rolling thunder. He clasped my forearm in a grip of iron, eyes twinkling with mirth beneath his bushy brows. "You've made good time. Come, stable your beast and let us see if your mettle matches your speed." </nc-section> <nc-section data-title="Version 2: Shadows of the Stables" data-color="green"> Dismounting Thunder at the castle gates, I led him toward the stables as the sun dipped below the horizon, painting the sky in fiery hues. There, silhouetted against the lantern-lit hay bales, stood Sir Roland, the local knight renowned for slaying the Wyrm of Blackmoor. "Frederick, lad," he called, his gravelly voice warm yet commanding, stepping forward to take Thunder's reins. "The road has tested you well. Now, the castle shall forge you anew." </nc-section> <nc-section data-title="Version 3: A Gruff Greeting" data-color="blue"> The gates creaked open, and I guided Thunder into the courtyard toward the stables, the scent of hay and horseflesh filling the air. A burly knight emerged from the stable doors—Sir Roland himself, his beard streaked with gray, armor scarred from countless battles. "Squire Frederick," he grunted approvingly, clapping a heavy hand on my shoulder as he inspected my travel-worn cloak. "Ye look sturdy enough. Unsaddle yer nag, and we'll talk of dragons and destiny over ale." </nc-section>
