<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight stepped from beneath the archway and raised a hand to halt me. His armor bore the scratches of long service, and a silver hawk gleamed on his breast. “You must be Frederick,” he said. “I’m Sir Roland, and I’ve been told to see you settled in.” Before I could answer, Thunder tossed his head and snorted. Sir Roland eyed the stallion with approval. “A spirited mount. Let’s hope his rider is, too.” </nc-section> <nc-section data-title="Version 2" data-color="green"> I guided Thunder toward the stables, where a knight waited beside the open doors. He was older than I’d expected, with kind eyes beneath the brim of his helmet. “Frederick?” he asked. “Sir Roland. Welcome to the castle.” He took Thunder’s reins while I swung down from the saddle. “You’ve arrived just in time,” he said, glancing toward the darkening sky. “The horses are restless tonight—and they’re rarely restless without reason.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> As I neared the stables, a knight strode out to meet me, his blue cloak stirring in the evening breeze. “Frederick, I presume?” he said. “Sir Roland. Your master sent word you were coming.” He offered a hand, then looked past me to the castle towers, where the last sunlight caught on the windows. His smile faded. “You’ve chosen an interesting night to arrive. Come inside—we have much to discuss.” </nc-section>
