<nc-section data-title="Version 1" data-color="red"> Thunder slowed as we passed through the castle gates. Near the stables, a knight in a weathered red cloak stepped into our path. “Frederick?” he asked. I swung down from the saddle and bowed. “Yes, sir.” “Sir Roland.” He glanced at Thunder, then at the dust on my boots. “You made good time. See that your horse is fed before you find your own supper.” I looked toward the castle, where the last sunlight burned in the high windows. My training, it seemed, had already begun. </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable yard smelled of hay and rain-soaked earth. I had barely dismounted when a broad-shouldered knight came forward and took Thunder’s reins while I loosened the girth. “You must be Frederick,” he said. “I’m Sir Roland.” I hurried to bow, but he gave the reins back with a small smile. “Finish tending to him first. He carried you here.” As I led Thunder into the stables, I caught sight of an old carving above the door: a dragon with its wings spread wide. One of its stone eyes had been worn smooth by countless passing hands. </nc-section> <nc-section data-title="Version 3" data-color="blue"> I reached the stables just as the castle bells rang for dusk. A knight waited beneath the archway, his silver hair bright against the gathering dark. “Frederick,” he said. It was not a question. “Sir Roland. Your father wrote that you were coming.” I dismounted, suddenly aware of how travel-stained my tunic was. Roland seemed not to notice. His gaze had lifted beyond me, toward the northern hills. “Put Thunder in the end stall,” he said. “Then come and find me. There’s something you ought to see before morning.” </nc-section>
