<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 watching the sunset. His armor bore the scratches of old battles, and a white dragon had been painted on his shield. “You must be Frederick,” he said. “I’m Sir Roland. Welcome to the castle.” I bowed, nearly tangling myself in Thunder’s reins. Roland caught the horse’s bridle before I could stumble. “We’ll begin with something simple tomorrow,” he said. “Learning which end of a horse to stand behind.” </nc-section> <nc-section data-title="Version 2" data-color="green"> By the time I reached the stables, the castle bells were ringing for supper. A knight in a green cloak stepped out beneath the lantern and raised a hand in greeting. “Frederick, is it? I’m Sir Roland.” He took Thunder’s reins and looked the stallion over. “Fine horse. Has he ever heard a dragon’s cry?” “I thought the dragons were gone,” I said. Roland glanced toward the darkening mountains. “So did I, until this morning.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> Thunder shied as a flock of pigeons burst from the stable roof. I had just managed to calm him when a knight emerged from the doorway, brushing straw from his sleeves. “Easy there,” he said, offering Thunder an apple. “And you must be Frederick. Sir Roland, at your service.” The stallion accepted the apple at once. I stared at him, astonished. Roland smiled. “Horses and squires have much in common. Both do better when they know they’re welcome.” </nc-section>
