<nc-section data-title="Version 1" data-color="red"> I led Thunder through the castle gates and toward the stables, where a broad-shouldered knight stood mending a broken bridle. He looked up as we approached. “You must be Frederick,” he said, setting the leather aside. “I’m Sir Roland. Welcome to the castle.” Thunder snorted and nudged his hand. Sir Roland chuckled. “At least one of you isn’t nervous. Come, let’s find him a stall before we see what sort of squire you’ll make.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Near the stables, Thunder shied at a stack of rattling buckets. I caught his reins, nearly stumbling into a knight emerging from the doorway. “Easy there,” he said, steadying us both. His armor was scratched, and a smear of straw clung to his cloak. “Sir Roland, at your service. You’re Frederick, aren’t you?” I nodded, embarrassed. “Good. You’ve arrived in time for supper—and a lesson.” He handed me a brush. “A knight’s horse eats before he does.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> As I dismounted beside the stables, a knight stepped out from the shadows beneath the eaves. His gaze went first to Thunder, then to the worn leather satchel at my side. “Frederick?” he asked. “I’m Sir Roland. Welcome.” He offered his hand, but before I could take it, a low cry drifted over the castle walls. Thunder stamped, and Sir Roland turned toward the darkening mountains. “Strange,” he murmured. Then he smiled, though his eyes remained troubled. “Come. We’ll get your horse settled.” </nc-section>
