<nc-section data-title="Version 1: The Stern Greeting" data-color="red"> I reined in Thunder as we approached the stables, the cobblestones slick with evening dew. A towering figure emerged from the shadows—Sir Roland, his armor dented from a hundred battles. "You're the new squire?" he barked, not waiting for my nod. "Tend to your horse, then report to the armory. We have no time for dawdling." His eyes swept over me like a blade assessing its next target. I dismounted quickly, my heart hammering against my ribs. </nc-section> <nc-section data-title="Version 2: The Warm Welcome" data-color="green"> A gentle hand steadied Thunder's reins as I slid from the saddle. Sir Roland stood before me, his face lined with kindness beneath a mop of graying hair. "Frederick, is it? Welcome to the castle," he said, his voice as rich as old oak. He pointed toward a trough of fresh water. "Let your stallion drink, then I'll show you to the hall. The cook always saves a warm meal for new arrivals." I smiled, the tension in my shoulders easing for the first time since leaving home. </nc-section> <nc-section data-title="Version 3: The Curious Observer" data-color="blue"> Sir Roland stood at the stable door, arms crossed, watching me dismount with an unreadable expression. He didn't speak at first, just studied Thunder's gait, my posture, the way I tied the reins. "A good animal," he finally said, his tone neutral. "You know how to handle him. That's something." He stepped closer, his eyes boring into mine. "But handling a horse is not the same as handling a sword. We'll see what you're made of tomorrow at first light." With that, he turned and disappeared into the gloom, leaving me alone with my thoughts. </nc-section>
