<nc-section data-title="Version 1" data-color="red"> Near the stables, Frederick was met by Sir Roland, a broad-shouldered knight with a weathered cloak and a kindly, appraising gaze. “You must be the new squire,” Roland said, inclining his head. “Come, then. Let me see if you know a horse from a fool’s errand.” Frederick straightened at once, both nervous and eager, as the stableboys fell silent to watch. </nc-section> <nc-section data-title="Version 2" data-color="green"> As Frederick approached the stables, a tall figure in polished mail stepped out of the shadows. Sir Roland offered him a firm, welcoming smile and a gloved hand. “Welcome to my yard,” he said. “The horses here are as sharp as any blade, so mind your footing.” Frederick nodded quickly, relieved by the knight’s warmth, though Roland’s keen eyes suggested no detail would escape his notice. </nc-section> <nc-section data-title="Version 3" data-color="blue"> By the time Frederick reached the stables, Sir Roland was already there, speaking softly to a groom while brushing dust from his gauntlet. He turned as Frederick neared, his stern face easing into a measured grin. “You’ll learn more from these horses than from half the pages in the library,” Roland said. “If you’re ready, squire, your first lesson begins now.” Frederick swallowed, then squared his shoulders and followed him inside. </nc-section>
