<nc-section data-title="Version 1" data-color="red"> Thunder slowed to a walk as we entered the stable yard. A broad-shouldered knight stood beside the open doors, one hand resting on the hilt of his sword. “Frederick?” he asked. I swung down from the saddle. “Yes, sir.” “I’m Sir Roland.” He took Thunder’s reins while I gathered my bag. “You’ve arrived before dark. That’s a promising start.” His smile faded as he glanced at the mud on my boots. “Tomorrow, we’ll see whether you’re as steady on your feet as you are in the saddle.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The smell of hay met me before I reached the stables. I dismounted, and Thunder nudged my shoulder, impatient for his supper. “You must be Frederick.” The knight who emerged from the stable doorway had silver at his temples and a brush in his hand. “Sir Roland. Welcome to the castle.” I bowed, nearly dropping my reins. He caught them before Thunder could wander off. “First lesson,” Sir Roland said, handing them back. “Never let go of your horse until you know who’s holding him.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> As I led Thunder towards the stables, a knight stepped out of the dusk and raised a hand in greeting. His cloak bore the castle’s crest, though its hem was dusty from travel. “Frederick,” he said. “I’m Sir Roland. I was told to expect you.” “Then I hope I haven’t kept you waiting.” “Only long enough to wonder whether you’d lost the road.” He smiled and opened the stable door. Warm lamplight spilled across the cobbles. “See to Thunder first. Then I’ll show you where you’ll sleep.” </nc-section>
