<nc-section data-title="Version 1: The Stern Inspection" data-color="red"> I reined Thunder to a halt just inside the castle yard, dust settling around us. A tall knight in polished plate armor strode from the stable shadows, his gauntleted hand resting on his sword pommel. “You must be the new squire,” he said, his voice like gravel rolling downhill. Sir Roland’s eyes swept over me, judging my mount, my saddle, the wear on my boots. “I trust you know how to care for a horse better than the last lad. Follow me—I’ll show you your duties before you get any ideas about glory.” </nc-section> <nc-section data-title="Version 2: The Warm Welcome" data-color="green"> As I swung down from Thunder’s back near the stable door, a cheerful voice hailed me. “Ho there, young Frederick! You made good time.” Sir Roland emerged with a grin, his face weathered but kindly, his armor unlatched at the shoulders as if he’d been mid-task. He clasped my arm in a firm, friendly grip. “Welcome to Castle Arundel. We don’t stand on ceremony here. Get your gear stowed, and I’ll have the cook save you a hot meal—you’ve a long day’s ride behind you.” </nc-section> <nc-section data-title="Version 3: The Quiet Mentor" data-color="blue"> The stable boy took Thunder’s reins without a word. I turned to find a man in a plain linen tunic and a worn leather vest leaning against the stable wall, arms crossed. Sir Roland’s eyes were the color of old steel—keen but not unkind. He studied me for a long breath, then nodded once. “You’re here to learn. That’s good. I’ll teach you what I know, but first we need to see if you have ears for the wind and patience for the stone.” He gestured toward the training grounds, already walking. “Let’s begin.”
