<nc-section data-title="Version 1: The Red Dawn" data-color="red"> As I slowed Thunder near the stables, a tall figure approached, clad in shining armor. Sir Roland, the venerable knight known throughout the realm, dismounted with a nod that was both firm and welcoming. “You must be Frederick,” he said, his voice like the clang of steel. “The castle’s future depends on brave hearts and steady hands. Welcome to your beginning.” </nc-section> <nc-section data-title="Version 2: The Verdant Greeting" data-color="green"> I guided Thunder into the bustling stables when a knight stepped forward, eyes kind yet keen. Sir Roland untied his helmet, revealing a weathered face softened with a gentle smile. "Ah, young squire," he said softly. "The road here is long, but your journey truly begins now. Come, I’ll show you to your quarters and your duties." His presence was reassuring amid the chaos of the castle yard. </nc-section> <nc-section data-title="Version 3: The Blue Twilight" data-color="blue"> As I tethered Thunder to a nearby post, a knight with piercing blue eyes approached, his armor shimmering in the dimming light. Sir Roland offered a commanding yet empathetic smile. “Greetings, Frederick,” he said calmly. “You have arrived in good time. There is much to learn, and I will be guiding you through it all. Follow me, and let’s begin your training at once.” His voice carried the weight of countless battles and wisdom. </nc-section>
