<nc-section data-title="Version 1" data-color="red"> I slowed Thunder beside the stables, where a knight in a weathered crimson cloak stood waiting. His gaze traveled from my dusty boots to the sword at my hip. “Frederick?” he asked. “Yes, sir.” “I am Sir Roland.” He took Thunder’s reins while I dismounted. “The stablemaster will see to your horse. You’ll come with me.” Beyond him, the castle doors stood open. I had imagined my first welcome would involve a feast, or at least a moment to catch my breath. Sir Roland was already walking, so I hurried after him. </nc-section> <nc-section data-title="Version 2" data-color="green"> Thunder came to a stop outside the stables and promptly lowered his head toward a trough. I was struggling with the saddle strap when a broad-shouldered knight approached and loosened the buckle with one practiced tug. “There,” he said. “Let the horse drink before you ask anything more of him.” I thanked him, embarrassed that I had needed the help. “Sir Roland,” he said, offering his hand. “You must be Frederick. I’ve been told you’re here to train.” I shook his hand. His grip was firm, but his smile put me at ease. “I am, sir.” “Then we’ll start in the morning. Tonight, you can learn where to find supper.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> As I led Thunder toward the stables, I saw a knight standing beneath the archway, his face half-hidden in the evening shade. He watched me pass, then called my name. I stopped. “I’m Frederick.” “Sir Roland,” he replied. “I was sent to meet you.” A groom emerged to take Thunder, but the horse shied from his hand. I stroked his neck until he settled, then passed over the reins. When I turned back, Sir Roland was studying me. “He trusts you,” the knight said. “We’ve ridden a long way together.” Sir Roland nodded toward the castle. “Come inside. You can tell me about the journey while we walk.” </nc-section>
