<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight stepped from beneath the archway. His polished breastplate caught the last red light of sunset. “You must be Frederick,” he said, offering a gauntleted hand. “Sir Roland. I’m to see you settled before the castle bells ring.” Frederick swung down from Thunder’s saddle and clasped his hand. “I’m ready to begin, sir.” Roland’s gaze lingered on the young squire’s travel-worn boots. “Good. The stables are a fine place to begin. A knight who cannot care for his horse has no business carrying a sword.” </nc-section> <nc-section data-title="Version 2" data-color="green"> A man in a green cloak waited beside the stable doors, one hand resting on the hilt of his sword. When Frederick approached, the knight smiled. “Frederick, I presume? Sir Roland.” He took Thunder’s reins with practiced ease. “You’ve arrived just in time. The stablemaster was beginning to wager you’d gotten lost.” Frederick glanced at the towering castle. “I nearly did.” “Then you’ve learned your first lesson,” Roland said, leading the stallion toward the stalls. “A castle is easier to find than its way around.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> As Frederick guided Thunder toward the stables, a knight emerged from the deepening blue shadows beneath their roof. His silver hair was tied neatly at his collar, and his eyes were sharp as drawn steel. “Frederick,” he said. “I’m Sir Roland. Welcome to the castle.” The knight reached for Thunder’s bridle, but the stallion tossed his head and stamped. Roland paused, studying the horse. “He’s wary,” Frederick said. “So should you be,” Roland replied. “There are things moving beyond these walls that give even good horses cause for fear.” Then he softened his voice. “Come. We’ll find him a stall—and speak of it tomorrow.” </nc-section>
