<nc-section data-title="Version 1: The Knight of Iron Counsel" data-color="red"> The stable yard was half-shadowed, all straw and sweat, when I drew Thunder to a careful halt. Near the tack room stood Sir Roland—broad-shouldered, plated like a walking fortress, his helm hanging from one arm as if it were merely a casual weight. “Frederick,” he said, the name landing with the steadiness of a hammer striking stone. His eyes moved over me the way a smith might appraise a blade—quietly, without pity. “You’re late enough that I can forgive you, and early enough that I can still correct you. Good. That means you’ll learn.” A groom straightened from a bucket with a nervous glance, and I felt my own posture tighten. “Yes, sir.” Sir Roland leaned closer, smelling faintly of oil and metal polish. “Your training begins when your pride stops moving faster than your feet. Can you hold a horse’s line without yanking the reins?” I swallowed. “I’ll try, sir.” He gave a brief nod. “Trying is for squires. Learning is for knights. For now—meet me at the training ring before the last bell. After that, you’ll earn the right to stand beneath those banners, not just stare at them.” </nc-section> <nc-section data-title="Version 2: A Lesson in Watching" data-color="green"> I hadn’t even stepped down before the voice came—clear, commanding, and oddly calm. “You there. Squire Frederick.” Turning, I found Sir Roland by the stables, where the horses shifted and stamped like restless thoughts. His armor caught the last of the daylight, glinting at odd angles; even unhelmeted, he looked like someone carved from duty. “You ride in,” he continued, “and you think the journey ends when the castle walls appear.” He gestured toward the stable door with one gauntleted finger. “It begins there. Horses remember everything—every jerk, every kindness, every fear you try to hide.” A mare snorted, as if offended by my clumsy arrival. My hands tightened on the reins, and for a heartbeat I thought I’d do something foolish. Sir Roland watched without rushing in. “Take a breath. Walk slowly. Speak softly. Let the animal decide you’re not a threat.” I approached the mare with the care he’d demanded, my voice quieter than my thoughts. Thunder, behind me, tossed his head and settled when I followed Sir Roland’s rhythm—steady, deliberate, unhurried. “Good,” the knight said at last. “You can listen. Now we’ll see if you can obey.” </nc-section> <nc-section data-title="Version 3: The Oath Beneath the Banners" data-color="blue"> The stables echoed with familiar sounds—hooves on packed earth, leather creaking on hooks, the low chatter of stable hands trying not to look impressed. Amid it all, Sir Roland stood like a closing door: firm, inevitable, and impossible to ignore. He greeted me as if we’d shared a battlefield rather than merely a schedule. “Frederick. New hands, new hopes, same old mistakes.” I felt my cheeks warm. “Sir Roland—thank you for meeting me.” “For meeting you?” He gave a short, dry smile. “I didn’t come to be polite. I came to make sure you’re the kind of squire the castle can use.” He nodded toward Thunder. “You’re riding for training, not for show. That horse will test you on your first mistake, because horses always do.” A stable boy hurried forward with a brush, and Sir Roland lifted a hand to stop him. “Brush later. Words first.” He lowered his voice, and the yard seemed to grow quieter around us. “There are knights who fight dragons in stories,” he said, “and knights who fight them in the space between commands—when panic tries to crawl into your throat. If you can’t keep your head while the world clatters, you won’t keep your life.” I forced myself to meet his gaze. “Then teach me how, sir.” Sir Roland’s eyes hardened, but not unkindly. “Very well. Tomorrow you’ll swing a blade. Today, you’ll learn where courage is stored—before steel ever touches flesh.” </nc-section>
