<nc-section data-title="Version 1" data-color="red"> Near the stables, a knight in a scarlet cloak stepped into my path. His armor was nicked and weathered, and a silver hawk gleamed on his breastplate. “You must be Frederick,” he said, offering a gloved hand. “Sir Roland. Welcome to the castle.” Before I could answer, Thunder tossed his head and stamped the earth. Sir Roland glanced at the stallion with a knowing smile. “Bold horse,” he said. “And a bold rider, if you’ve made it here before nightfall. Come along, lad. There’s much to learn—and little daylight left.” </nc-section> <nc-section data-title="Version 2" data-color="green"> I guided Thunder toward the stables, where lanterns were beginning to glow. A broad-shouldered knight stood beside the entrance, speaking with a stablehand. When he saw me, he dismissed the boy with a nod and approached. “Frederick?” he asked. “I’m Sir Roland, the local knight. Your arrival has been expected.” He took Thunder’s reins, then gave the stallion an appraising look. “A fine companion. Let’s get him settled, and then I’ll show you where you’ll be staying. The castle has a way of feeling strange after dark.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> Thunder slowed as we reached the stables. A knight waited beneath the archway, his blue cloak stirring in the evening breeze. He rested one hand on the hilt of his sword, though his expression was warm. “Frederick,” he said, as if he’d known me all my life. “Sir Roland. I’m glad you arrived safely.” His gaze shifted to the castle beyond us, where the last sunlight caught on the high windows. For a moment, his smile faded. “Bring your horse inside,” he said quietly. “There are things about this place you should hear before night falls.” </nc-section>
