<nc-section data-title="Version 1" data-color="red"> As Thunder slowed near the stables, a knight stepped from beneath the archway, his polished armor catching the last red rays of sunset. “You must be Frederick,” he said. “I’m Sir Roland, the local knight. Welcome to the castle.” Frederick slid from the saddle and bowed, trying not to show how stiff his legs felt after the ride. Sir Roland’s gaze lingered on the young squire’s travel-worn clothes, then softened. “Come along,” he said. “The horses are eager for their supper, and I suspect you are too.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable doors stood open, spilling the warm smells of hay and horses into the evening air. A broad-shouldered knight waited beside them, one hand resting on the pommel of his sword. “Frederick?” he called. “Yes, sir.” “I’m Sir Roland.” He offered a firm handshake, then reached to steady Thunder’s bridle. “You’ve arrived just in time. The stablemaster was beginning to wonder whether our new squire had lost his way.” Frederick smiled, relieved by the knight’s friendly manner. “I’m glad to be here, sir.” “Then let’s get your horse settled,” Roland said. “There will be plenty of time for introductions tomorrow.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> Thunder’s hooves clattered to a halt beside the stables. Before Frederick could dismount, a knight emerged from the shadows, his cloak stirring in the breeze. “Easy, lad,” he said, reaching for the reins. “A tired horse deserves a gentler welcome than a sudden stop.” Frederick swung down and bowed. “Thank you, sir.” “Sir Roland,” the knight replied. “I keep watch over this stretch of the kingdom—and, for now, over you. Welcome to the castle, Frederick.” For a moment, Roland studied him as if weighing more than the journey’s dust on his clothes. Then he nodded toward the stable doors. “Come. Let’s see your horse cared for before the night grows cold.” </nc-section>
