<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight stepped from beneath the lantern light. His cloak bore the castle’s silver wolf, and a sword hung at his side. “You must be Frederick,” he said, offering a gauntleted hand. “I’m Sir Roland. Welcome to the castle—and to the beginning of a very long day.” I swung down from Thunder’s saddle and shook his hand. Sir Roland’s grip was firm, but his smile was warm. “Come along,” he said, taking Thunder’s reins. “The stablemaster will see your horse settled. Then I’ll show you where a squire is expected to be before dawn.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable doors stood open, spilling golden light across the cobbles. A knight in a weathered green surcoat waited beside them, his arms folded over a breastplate polished bright as the evening sky. “Frederick?” he called. I nodded, and he gave a brisk bow. “Sir Roland. I’ve been told you’re to train here.” His gaze flicked to Thunder, then back to me. “A fine horse. Let’s hope his rider has the same good sense.” Before I could answer, Roland took the reins and led Thunder toward an empty stall. “Come on, lad. There’s much to learn, and the stables are as good a place as any to begin.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> A figure emerged from between the stable doors just as I reached them. He was tall and lean, with a silver streak at his temple and a knight’s blue cloak fastened at one shoulder. “Frederick,” he said, as though he had been expecting me. “Sir Roland. I’m responsible for your training.” He glanced toward the darkening sky. “You’ve arrived later than planned.” “I’m sorry, sir. The road—” “Can wait until you’ve seen to your horse.” His stern expression softened as he reached for Thunder’s bridle. “A squire who forgets his mount won’t make much of a knight. Come. We’ll get him settled, and then you can tell me what delayed you.” </nc-section>
