<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 said, offering a gauntleted hand. “I’m Sir Roland. Welcome to the castle.” Frederick dismounted, trying not to stumble after the long ride. The knight’s grip was firm, but his smile was warm. “Your training begins at dawn,” Sir Roland said. “But tonight, you’ll meet the horses—and learn that they’re often better judges of character than men.” </nc-section> <nc-section data-title="Version 2" data-color="green"> A stable door swung open, and a knight in a green-trimmed cloak emerged, brushing straw from his sleeve. “You must be Frederick,” he said. “Sir Roland, at your service.” Frederick bowed. “I’m honored, sir.” “And I’m glad you’ve arrived before nightfall,” Roland replied, nodding toward the stalls. “Come along. We’ll find your horse a place, then I’ll show you where you’ll sleep. Tomorrow, the real work begins.” As they entered the stable, the horses stirred—and one gave a curious, almost knowing whinny. </nc-section> <nc-section data-title="Version 3" data-color="blue"> A tall figure waited beside the stables, blue cloak stirring in the evening breeze. When Frederick approached, the knight raised a hand in greeting. “Frederick? I’m Sir Roland, the local knight. I was told to expect you.” “Yes, sir,” Frederick answered, climbing down from his horse. Roland glanced at the stallion, then at the young squire. “A fine mount. Let’s get him settled. The castle can wait a moment; a tired horse deserves kindness before a new arrival deserves ceremony.” Together, they led Thunder into the stable, where warm hay and the quiet rustle of horses welcomed them. </nc-section>
