<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 rays of sunset. “You must be Frederick,” he said, offering a gauntleted hand. “I’m Sir Roland. Welcome to the castle.” Frederick swung down from Thunder’s saddle and returned the greeting. The knight’s grip was firm, but his smile was kind. “Bring your horse inside,” Sir Roland said. “The stablemaster will see him settled. Then we’ll find you a bed—and discover whether you’re as eager to train as you look.” </nc-section> <nc-section data-title="Version 2" data-color="green"> A man in a green cloak waited beside the stables, one hand resting on the pommel of his sword. His weathered face softened when Frederick rode up. “Frederick, I presume?” he asked. “Sir Roland. I was told to expect you before nightfall.” “I’m sorry if I’m late,” Frederick said, sliding from Thunder’s back. “Not at all. A knight should learn to arrive with a little drama.” Roland’s eyes twinkled as he took the reins. “Come along. We’ll get your horse settled, and then I’ll show you where your training begins.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> A tall knight stood waiting near the stables, where lanternlight shone blue against the dusk-dark stones. He wore no helmet, and a thin scar crossed one cheek. “Frederick?” he called. “Yes, sir.” “Sir Roland,” the knight said, inclining his head. “You’ve had a long ride. Let’s see your horse cared for before we speak of lessons.” As Roland led Thunder toward the stable doors, Frederick noticed the knight glance toward the distant hills. For a moment, the welcome in his face gave way to something troubled. “Tomorrow,” Roland said quietly, “your training begins. Tonight, get some rest. The kingdom may soon ask more of you than swordwork.” </nc-section>
