<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight waited beneath the fluttering banners. His armor was scuffed from use, and a white rose was painted on his shield. “You must be Frederick,” he said, offering a gauntleted hand. “Sir Roland. Welcome to the castle.” Frederick slid down from Thunder and returned the greeting. From the stables came the warm smell of hay and the restless stamp of hooves. “Your training begins at dawn,” Sir Roland said. “But tonight, you’ll learn the first rule of this place: a good knight tends his horse before he tends himself.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Thunder slowed as Frederick reached the stables. A knight in a green cloak stepped from the wide doorway, lantern light gleaming on the silver trim of his armor. “Frederick, I presume?” he asked. “I am Sir Roland, the castle’s knight. You’ve arrived just in time—the stablemaster was beginning to worry about that magnificent horse.” Frederick dismounted and patted Thunder’s neck. Sir Roland smiled, but his gaze lingered on the stallion’s dark, watchful eyes. “Bring him inside,” the knight said quietly. “And keep close. The horses have been restless since nightfall.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> At the stable yard, a tall knight stood beside the open doors, his blue cloak stirring in the evening breeze. He raised a hand as Frederick rode up. “Easy there,” he called, and Thunder obediently slowed. “You’re Frederick, the new squire. I’m Sir Roland.” The knight’s voice was stern, but his smile was kind. He helped Frederick from the saddle, then took Thunder’s reins. “Your journey’s over for tonight,” he said. “Let’s see your horse settled, then I’ll show you where you’ll sleep. Tomorrow, we find out what you’re made of.” </nc-section>
