<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight waited beneath the fluttering banners. His armor was polished bright, though a few dents marked its surface, and a silver hawk was painted across his shield. “You must be Frederick,” he said, offering a gauntleted hand. “I’m Sir Roland, the local knight. Welcome to the castle.” Frederick swung down from Thunder and returned the greeting. Behind Sir Roland, the stable doors stood open, warm with lamplight and the smell of hay. From somewhere within came a sudden, frightened whinny. Sir Roland’s smile faded. “Seems your first evening here may be more eventful than you hoped.” </nc-section> <nc-section data-title="Version 2" data-color="green"> A lantern bobbed beside the stables as a knight strode out to meet Frederick. He wore a green cloak over his mail, and a pale scar ran from his temple to his jaw. “Frederick, I presume?” he said. “Sir Roland. I keep watch over this valley—and, for tonight, I’ll see you settled in.” Frederick bowed, glancing at the stalls behind him. Thunder tossed his mane, restless after the ride. “Good horse,” Roland said, giving the stallion a respectful look. “The stablemaster will find him a place. As for you, there’s a warm meal waiting—and a question I suspect you’ll want answered.” “What question?” Roland turned toward the castle, where a bell began to toll. “Why the mountain has been glowing after dark.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> Frederick guided Thunder toward the stables, where a knight stood waiting beneath the archway. His blue surcoat bore the castle’s silver tower, and his expression softened as the young squire approached. “Welcome, Frederick,” he said. “Sir Roland, at your service.” “I’m honored, sir,” Frederick replied, dismounting. Roland clasped his forearm. “You’ve arrived at a curious hour. The horses have been uneasy all afternoon, and the castle hounds refuse to go near the north road.” Thunder snorted and stamped at the stable threshold. From deep within the dark aisle, something answered with a low, rumbling growl. </nc-section>
