<nc-section data-title="Version 1: A Warm Welcome" data-color="red"> As I dismounted Thunder, a tall figure emerged from the shadows of the stables. Sir Roland, his armor gleaming even in the fading light, extended a hand. "Welcome, Frederick," he said, his voice warm and steady. "The kingdom has been expecting you. Your training begins at dawn." </nc-section> <nc-section data-title="Version 2: A Stern Greeting" data-color="green"> Thunder’s hooves had barely settled before a gruff voice cut through the air. Sir Roland stood before me, arms crossed, his expression unreadable. "You’re late," he said bluntly. "The stables close at dusk. Tomorrow, you’ll learn punctuality—or you’ll learn the cost of tardiness." </nc-section> <nc-section data-title="Version 3: A Mysterious Encounter" data-color="blue"> The stables were eerily quiet as I tied Thunder to a post. A cloaked figure stepped forward, the dim light revealing Sir Roland’s weathered face. "Frederick," he murmured, glancing over his shoulder as if expecting unseen eyes. "There’s much you don’t know about this castle. Meet me at the old watchtower at midnight." </nc-section>
