<nc-section data-title="Version 1: Sir Roland's Stern Welcome" data-color="red"> As I dismounted from Thunder, a gruff voice called out behind me. "You must be the new squire." I turned to see a towering figure in burnished armor, his weathered face etched with scars from countless battles. Sir Roland, the castle's most formidable knight, stood with arms crossed, his piercing gaze assessing me like a blacksmith examining raw ore. "I trust you're ready for hard work, boy. There's no room for weakness in these halls. Come—we'll get your horse settled, then I'll show you to the barracks." His tone was harsh, but something in his eyes suggested a hidden kindness beneath the gruff exterior. </nc-section> <nc-section data-title="Version 2: Sir Roland's Courtly Greeting" data-color="green"> A tall knight emerged from the stable entrance, his armor polished to a mirror shine. "Welcome, young Frederick!" Sir Roland's voice was warm and inviting, a stark contrast to his intimidating appearance. He clasped my shoulder firmly, a genuine smile crossing his face. "I am Sir Roland, and I shall oversee your training here. Come, let us see to your magnificent steed first—Thunder is a fine name for such a noble creature. Then we shall take refreshment in the great hall, where you can meet the other squires and hear tales of the kingdom's past glories." </nc-section> <nc-section data-title="Version 3: Sir Roland's Cryptic Encounter" data-color="blue"> A shadow moved across the stable yard. Sir Roland emerged from the twilight, his silhouette framed by the dying sunlight. He said nothing at first, merely studying me with an intensity that made my skin prickle. "So, you are Frederick," he finally spoke, his voice low and measured. "Word reaches even us in these remote halls. There is much you need to know about this place—and much that cannot be spoken aloud." He gestured toward the castle's highest tower, where a single light burned in a narrow window. "But first, tend to your horse. We will speak more when darkness falls." </nc-section>
