<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight stepped out to meet me. His polished breastplate caught the last red light of sunset, and a silver dragon gleamed on his cloak. “You must be Frederick,” he said, offering a gauntleted hand. “Sir Roland. Welcome to the castle—and to your training.” I swung down from Thunder’s saddle and clasped his hand. Behind him, the stable doors stood open, warm with lamplight and the smell of hay. Somewhere inside, a horse stamped and snorted. Sir Roland glanced at the darkening sky. “Come along, squire. There’s much to learn before dawn.” </nc-section> <nc-section data-title="Version 2" data-color="green"> As I led Thunder toward the stables, a knight emerged from between the stalls, wiping his hands on a green wool cloak. He was older than I’d expected, with a neatly trimmed beard and a scar that crossed one eyebrow. “Frederick?” he asked. “Yes, sir.” “Sir Roland,” he said, with a nod. “I look after the castle’s horses—and the squires who bring them here.” His gaze softened as he took Thunder’s reins. “You’ve had a long ride. Let’s get your stallion settled, and then I’ll show you where you’ll be sleeping.” The stable was warm and bright, and for the first time since leaving home, I felt I might belong. </nc-section> <nc-section data-title="Version 3" data-color="blue"> The stable yard was almost empty when a knight strode through the gates, his blue cloak snapping in the evening wind. He stopped before me and gave a crisp salute. “Frederick, I presume. Sir Roland, at your service.” I returned the salute awkwardly, nearly losing my grip on Thunder’s reins. Sir Roland hid a smile. “Your first lesson,” he said, “is to keep hold of your horse.” Thunder chose that moment to toss his head and nicker. Roland laughed, then led us toward the stable doors. “Come on, lad. We’ll see whether he’s as brave as his rider.” </nc-section>
