<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 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 are no place for dawdling. See to your horse, then report to the barracks. We’ve no time for laziness here." </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 hood falling back to reveal Sir Roland’s weathered face. His eyes held a glint of something unreadable. "Frederick," he murmured, "the castle is not as it seems. Trust no one—not even me—until you’ve proven yourself." With that, he turned and vanished into the twilight. </nc-section>
