<nc-section data-title="Version 1: Sir Roland’s Welcome" data-color="red"> The iron smell of horses filled the air as Thunder was led toward the stables. I followed, boots thudding softly on the packed earth, and tried not to stare at the rows of bridles and saddles hung like trophies. Before I could find a stableboy to ask about my assignment, a voice cut through the commotion—steady, confident, and polished by years of command. “Frederick.” I turned. Sir Roland stood just inside the stable yard, broad-shouldered beneath a breastplate still bright from cleaning. His cloak was the color of storm clouds, and a gold-trimmed helm hung from his arm like a promise. He looked me over as if weighing a sword’s balance. “So you’re the new squire,” he said, eyes narrowing with approval. “Then keep your head up and your hands busy. This place runs on discipline—or it grinds men down.” He gestured toward the tack room. “Start there. If you can’t handle leather, straps, and oil, you won’t last long enough to polish steel.” My throat tightened, but I nodded. “Yes, sir.” Sir Roland’s mouth quirked—almost a smile. “Good. And don’t worry about Thunder. He can smell fear. Give him calm and he’ll give you comfort.” The stable rang with quiet sounds: a stall door closing, a horse shifting weight, the faint clink of bits. Yet beneath it all, I felt the castle watching—waiting to see whether I belonged. </nc-section> <nc-section data-title="Version 2: Steel and Orders" data-color="green"> As Thunder was settled into his stall, I tried to memorize everything—how the harnesses were hung, where the lantern hooks stood, which stones near the door stayed slick even in dry weather. The stables were alive with the rhythm of work, and it made my nerves feel louder. A figure stepped into the yard with the unmistakable gravity of a man who expected obedience. Sir Roland approached without hurry. His armor didn’t clatter; it seemed to hush the world around him. He wore his authority like a second skin. “You’re Frederick,” he said, not asking, measuring. “Yes, sir,” I replied, turning my hands outward where they were empty. I’d learned early that empty hands signaled honesty. Sir Roland’s gaze moved from my face to my boots, then to the manner in which I stood. “A squire is not a decoration. You’re here to learn what knights forget they ever knew.” He walked past the stalls, stopping beside a workbench where oil and rags lay neatly arranged. With two fingers, he tapped the edge of a saddle as if it were a lesson written in wood. “From this moment, you’ll speak only when you must. You’ll listen the rest of the time. And when a knight orders you to fetch something, you fetch it fast—without searching for the fastest route first.” I swallowed. “Understood.” Sir Roland turned back to me. “Good. One more thing.” His voice lowered, sharpened. “This castle has ears. If you’re late, if you’re careless, if you’re pretending… they’ll know before I do.” For a heartbeat, all I could hear was Thunder breathing. Then Sir Roland nodded once toward the tack room. “Begin.” </nc-section> <nc-section data-title="Version 3: The Sound of a Promise" data-color="blue"> I’d barely finished tying the last strap when the stable doors opened and the yard filled with cold evening air—and with Sir Roland. He arrived like a bell’s final note: clear, commanding, impossible to ignore. Even the horses seemed to settle, as if they recognized authority by instinct. “Frederick,” Sir Roland called, his voice carrying across the straw and iron. “Step forward.” I did, wiping my palms on my tunic despite the fact they were already streaked with oil. Up close, Sir Roland looked less like a legend and more like a man forged from duty: lines at the corners of his eyes, a scar half-hidden beneath his beard, and eyes the color of tempered steel. He studied me without impatience. “You rode in on Thunder,” he observed, as though that detail mattered as much as my name. “Yes, sir.” “Then you’ve already learned one truth,” he said. “A horse is not a tool. It’s a partner. Treat it as one and it will carry you through what you thought you’d never survive.” Sir Roland leaned closer, the leather creak of his gauntlet loud in the quiet. “Now listen carefully. Your training begins today, but not with a sword.” He pointed toward the stable’s far wall, where a rack held whetstones, brushes, and coils of clean rope. “Polish the tack. Check the buckles. Count what’s missing. A knight’s gear is a map—if you neglect it, you’ll get lost when it matters.” My chest tightened with both fear and something like relief. Orders I could follow. Tasks I could do. “Yes, sir,” I said again, steadier this time. Sir Roland straightened, giving one final nod toward the doors beyond the yard. “And when the hour comes, you’ll accompany me. Not to watch. To learn.” The promise in his words settled in my bones as the castle’s shadows lengthened. </nc-section>
