<nc-section data-title="Version 1" data-color="red"> I led Thunder beneath the castle arch and followed the scent of hay to the stables. A broad-shouldered knight stood in the yard, watching a groom struggle with a stubborn mule. “You must be Frederick,” he said as I dismounted. “I’m Sir Roland.” I bowed, nearly catching my boot in the stirrup. His smile softened my embarrassment. “See to your horse first,” he said. “A good squire remembers who carried him.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Thunder shied as a bucket clattered beside the stables. A knight in a weathered blue cloak caught his bridle before I could steady him. “Easy, lad,” he murmured, stroking Thunder’s neck. Then he looked up at me. “Frederick, I take it? Sir Roland. Welcome to the castle.” “Thank you, sir.” I slid from the saddle, grateful to have both feet on the ground. Roland studied Thunder’s trembling flanks. “Let’s get him settled. There’ll be time enough to show you the training yard tomorrow.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> I found Sir Roland outside the stables, examining a curious black feather caught in a crack between the stones. It was longer than my hand and shimmered red at the edges. He tucked it beneath his cloak when he saw me. “Frederick? I’m Sir Roland. Your father wrote that you’d be arriving today.” He helped me unsaddle Thunder, though his gaze kept straying toward the darkening hills. “Is something wrong, sir?” I asked. “Perhaps,” he said. “But you’ve had a long ride. Come inside, and I’ll tell you what we’ve found.” </nc-section>
