<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight stepped from beneath the archway, his polished armor catching the last red light of sunset. “Frederick, I presume?” he called, raising a hand to halt the stable boys. “I’m Sir Roland. Welcome to the castle.” Frederick swung down from Thunder’s saddle and bowed, trying not to show how sore the ride had left him. Sir Roland’s stern expression softened. “Your training begins at dawn. For tonight, see to your horse—and get some rest. You’ll need it.” </nc-section> <nc-section data-title="Version 2" data-color="green"> A stable door swung open, spilling the warm scents of hay and leather into the evening air. A knight in a green-trimmed cloak emerged, wiping his hands on a cloth. “You must be Frederick,” he said. “Sir Roland, at your service.” Frederick nodded, leading Thunder toward the nearest stall. “I was told to report to the castle.” “And so you have.” Roland took the reins with an easy smile. “A squire’s first duty is often to the horse that carried him here. Let’s make sure your friend is settled before we find you a bed.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> By the stables, a knight waited beneath the fluttering blue banners. His silver hair was tied at the nape of his neck, and a sword rested at his hip. “Frederick?” he asked as the young squire dismounted. “Sir Roland. I was beginning to think the road had swallowed you.” Thunder snorted, stamping at the cobbles. Roland glanced at the stallion, then at Frederick. “Good spirit. You’ll need to learn how to guide it—both in a horse and in yourself. Come along. We’ll start with the stables.” </nc-section>
