<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight stepped out to meet me. His polished armor caught the last red light of sunset, and a sword hung at his side. “You must be Frederick,” he said, offering a gloved hand. “I’m Sir Roland. Welcome to the castle.” I swung down from Thunder and shook his hand. His grip was firm enough to make my fingers ache. “Your training begins at dawn,” he said, eyeing my travel-worn clothes. “Tonight, you’ll eat, rest, and learn where not to leave your horse.” Thunder snorted as if he already knew. Sir Roland laughed. “Good. The horse has more sense than most new squires.” </nc-section> <nc-section data-title="Version 2" data-color="green"> I guided Thunder toward the stables, where a knight in a green-trimmed cloak was waiting beside the open doors. “Frederick?” he called. “Yes, sir.” “Sir Roland,” he said, with a brisk nod. “I look after the squires here—and, when necessary, keep them from getting themselves killed.” He took Thunder’s reins and passed them to a stable hand. “Your horse will be cared for. You, meanwhile, should follow me. The master-at-arms is eager to meet the castle’s newest arrival.” My stomach tightened. I had barely crossed the threshold, and already the adventure seemed to be catching up with me. </nc-section> <nc-section data-title="Version 3" data-color="blue"> A knight stood near the stables, his blue cloak stirring in the evening breeze. He watched me dismount, then gave Thunder an approving glance. “Good seat,” he said. “And a fine horse. I’m Sir Roland.” I bowed, suddenly aware of the dust on my boots and the nerves knotting in my chest. “Frederick, sir. I’ve come to begin my training.” “Then you’ve come to the right place.” His stern expression softened. “The castle can seem a little daunting on your first night. I’ll show you to the squires’ quarters—and tomorrow, we’ll see what you can do with a sword.” Behind him, the stable doors creaked open, warm lamplight spilling across the cobbles. </nc-section>
