<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight stepped from beneath the lanterns and raised a hand to stop me. His red cloak was pinned with a silver dragon. “Frederick, I presume?” he said. “Sir Roland. Welcome to the castle.” I swung down from Thunder, trying not to show how stiff my legs had grown. Sir Roland’s gaze flicked to the stallion, then to the darkening sky beyond the walls. “You’ve arrived on an interesting evening,” he said quietly. “The old watchtower has just sounded its alarm.” </nc-section> <nc-section data-title="Version 2" data-color="green"> I guided Thunder toward the stables, where a knight in a weatherworn green cloak waited beside the open doors. He had a kindly face, though the scar along his jaw made him look as if he’d seen more battles than he cared to remember. “Frederick?” he asked. “I’m Sir Roland. Let’s get your horse settled before nightfall.” As he reached for Thunder’s reins, the stallion shied and stamped. Sir Roland’s smile vanished. From somewhere deep beneath the stable floor came a low, rumbling growl. “Best keep hold of him,” the knight murmured. “Something has been stirring under the castle.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> A knight in a blue surcoat met me near the stables, where the smell of hay and warm horses softened the chill of evening. He bowed with crisp formality. “Frederick. Sir Roland, at your service—and your instructor, if the captain’s letter was correct.” I nodded, suddenly aware of the mud on my boots and the travel dust on my cloak. Sir Roland only grinned. “Good. The finest knights arrive looking as though they’ve already survived a quest.” He took Thunder’s bridle and glanced toward the castle, where a strange golden light pulsed behind the highest windows. “Come along. I suspect your training may begin sooner than either of us expected.” </nc-section>
