<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, the local knight, approached with a warm smile. "Welcome, Frederick," he said, his voice as sturdy as the sword at his hip. "I've been expecting you. The kingdom needs young squires like yourself." </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 armor gleaming under the fading sunlight. "You're late," he said, his gaze sharp. "Punctuality is a knight's first lesson. Follow me, squire." </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. "Frederick," he murmured, glancing over his shoulder as if expecting unseen eyes. "We must speak in private. The castle walls have ears." </nc-section>
