<nc-section data-title="Version 1: The Stern Welcome" data-color="red"> Thunder's hooves clattered against the cobblestones as I reined him to a halt in the castle yard. A towering knight in burnished steel plate strode towards me, his visor raised to reveal a weathered face with a scar cutting through his left eyebrow. He did not smile. "You're the new squire, then? Frederick?" His voice boomed across the yard. "I am Sir Roland. Dismount. I'll not have a boy who cannot handle his own horse." </nc-section> <nc-section data-title="Version 2: The Warm Greeting" data-color="green"> I slid from Thunder's saddle just as a cheerful voice called out, "Well met, lad! You must be Frederick!" A knight with sun-bleached hair and a kind, open face approached me, his armor gleaming with polish. He clapped me on the shoulder with a gauntleted hand. "I'm Sir Roland. We've been expecting you. The stablemaster will see to your horse—fine beast, by the way. Come, let's get you some supper before the real work begins." </nc-section> <nc-section data-title="Version 3: The Mysterious Figure" data-color="blue"> The yard was quiet as I dismounted, the only sound the jingle of my spurs and the distant clang of a blacksmith's hammer. I turned to see a knight emerge from the shadows of the stable, his dark cloak billowing despite the still air. His face was half-hidden by his hood, but his eyes caught the last rays of sunlight. "Frederick," he said, his voice low and resonant. It was not a question. He knew my name. "I am Sir Roland. Follow me. There is much you need to know, and little time to tell it." </nc-section>
