<nc-section data-title="Version 1" data-color="red"> I reined Thunder in beside the stables, where a broad-shouldered knight waited beneath the archway. His red cloak stirred in the evening wind. “Frederick?” he asked. I dismounted and bowed. “Yes, sir.” “Sir Roland.” He glanced at Thunder, then at my dusty boots. “You’ve come a long way. See to your horse first. We’ll speak of your training after.” I liked him better for that. As I led Thunder inside, I noticed deep scratches scored across the stable door—far too high for any horse to have made. </nc-section> <nc-section data-title="Version 2" data-color="green"> The castle stables smelled of hay and warm leather. I had barely swung down from Thunder’s saddle when a knight stepped out carrying a bucket of water. “You must be Frederick,” he said, setting it where Thunder could drink. “I’m Sir Roland.” I started to bow, but Thunder nudged my shoulder and nearly sent me stumbling. Sir Roland laughed. “Keep your feet, lad. You’ll need them tomorrow.” “Tomorrow?” “At dawn,” he said. “Tonight, you and your horse have earned a rest.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> As I approached the stables, a knight in a blue surcoat emerged from the shadows. He raised a hand, and I drew Thunder to a halt. “Welcome to the castle, Frederick. I’m Sir Roland.” His voice was kind, though his eyes lingered on the darkening sky. From somewhere beyond the walls came a low, distant rumble. Thunder tossed his head. “Was that thunder?” I asked. Sir Roland took the reins while I dismounted. “I hope so,” he said. </nc-section>
