<nc-section data-title="Version 1" data-color="red"> Near the stables, Frederick swung down from his horse and was met by a broad-shouldered knight in a weather-worn cloak. “You must be Frederick,” the knight said, offering a gloved hand. “Sir Roland. Welcome to the castle.” Frederick straightened, suddenly aware of the mud on his boots and the journey’s dust on his tunic. “I’m honored to meet you, sir.” “Save your honors for the training yard,” Roland replied with a grin. “For now, let’s see that your horse is settled. A squire’s first duty is to care for the one who carried him here.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable doors stood open, spilling the warm scent of hay into the evening air. As Frederick led his horse inside, a knight emerged from the shadows between the stalls. “Frederick?” he asked. “Yes, sir.” “Sir Roland,” the knight introduced himself, his silver-trimmed armor catching the last light of sunset. “I was told to expect you. You’ve arrived just in time—the horses are restless, and the stablemaster could use another pair of hands.” Frederick glanced toward the shadowy stalls, where something snorted and stamped. Roland’s smile turned wry. “Don’t worry. They’re friendlier than they sound. Usually.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> A figure waited beside the stables, one hand resting on the pommel of a sheathed sword. His armor was scarred from old battles, but his posture was as straight as a spear. “Frederick,” he said. “I’m Sir Roland, the knight who’ll see you settled.” Frederick bowed quickly. “I’m pleased to meet you, sir.” Roland studied him for a moment, then nodded toward the stable doors. “Good. You’ll need that courtesy—and a little courage. The castle can be a strange place after dark.” From within the stables came a sudden, shuddering clang. Roland sighed. “And it seems your first adventure has already begun.” </nc-section>
