<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight waited beneath the fading light, one gloved hand resting on the pommel of his sword. “Frederick, I presume?” he called as the young squire approached. “I’m Sir Roland. Welcome to the castle.” Frederick swung down from his horse and bowed, suddenly aware of the dust on his boots and the travel-stains on his cloak. “Thank you, sir.” Roland’s stern expression softened. “You’ll have time to polish your armor tomorrow. Tonight, let’s see that your horse is fed—and that you get a warm meal before your training begins.” </nc-section> <nc-section data-title="Version 2" data-color="green"> A stable hand hurried out to take Frederick’s reins, but a knight stepped forward before he could dismount. “Easy there,” the knight said, smiling as the horse tossed its head. “I’m Sir Roland. The stablemaster tells me you’ve had a long ride.” Frederick greeted him with a respectful bow. “I’m Frederick, sir. I’ve come to begin my training.” “Then you’ve arrived at the right place.” Roland glanced toward the stable doors, where lamplight gleamed across rows of neatly kept stalls. “Your horse will be looked after. Come along—I’ll show you where you’ll be sleeping, and tell you what the masters expect of a new squire.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> Frederick had nearly reached the stables when a knight emerged from between the stalls, his silver cloak clasp catching the last of the sunset. “You must be the new squire,” he said. “Sir Roland. I keep watch over this part of the castle.” Frederick dismounted and offered his name. Roland studied him for a moment, taking in his road-worn clothes and the set of his shoulders. “Long journey?” the knight asked. “Yes, sir.” “Good. The first lesson of a squire is learning to arrive tired and still stand straight.” With a hint of amusement, Roland nodded toward the stable. “Come, Frederick. Let’s find your horse a stall—and you a place by the fire.” </nc-section>
