<nc-section data-title="Version 1" data-color="red"> Thunder slowed as we reached the stables. A broad-shouldered knight stood beneath the archway, his red cloak stirring in the evening wind. “Frederick?” he asked. I dismounted and bowed. “Yes, sir.” “I’m Sir Roland. Your training begins at dawn.” His gaze shifted to Thunder, who had gone strangely still. From somewhere beyond the castle walls came a low, distant sound—too deep to be a bell. Roland’s hand settled on his sword. “Best get him inside.” </nc-section> <nc-section data-title="Version 2" data-color="green"> I found the stables by following the smell of hay and the sound of horses settling for the night. Thunder nudged my shoulder as I loosened his reins. “He likes you,” said a voice behind me. “That’s a promising start.” I turned to find a knight leaning against the stable door, his armor dusty from travel. He offered me a hand. “Sir Roland. You must be Frederick.” “Yes, sir.” I shook his hand, trying not to stare at the old burn mark across his gauntlet. Roland noticed. “There’s a story behind that,” he said. “If you’re still curious after mucking out the stalls tomorrow, I might tell you.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> By the time I reached the stables, dusk had turned the castle windows gold. I swung down from Thunder’s back and nearly collided with a knight carrying a bucket of oats. “You must be Frederick,” he said, catching the bucket before it spilled. “I’m Sir Roland.” I bowed hastily. He waved the gesture away and held out the oats for Thunder, who accepted them at once. “Good,” Roland said. “He’s made himself at home. Come along—I’ll show you where you’ll sleep.” As I followed him across the yard, I glanced up at the castle’s highest tower. Carved into its stone was a dragon with its wings spread wide. In the fading light, it looked almost ready to fly. </nc-section>
