<nc-section data-title="Version 1: The Meeting by the Stables" data-color="red"> Smoke from the smithy curled over the yard as I led Thunder toward the stables. The place smelled of straw, linseed, and horse-sweat—honest scents that made my nerves settle. Near the tack room stood a broad-shouldered knight in a weathered helm, polishing his gauntlet with slow care, as though each scrape of cloth were a vow. “Easy there,” he said when Thunder tossed his head. His voice carried the rough steadiness of stone walls. He lifted his visor just enough for me to see a pair of sharp eyes beneath. “You must be Frederick,” Sir Roland announced, as if he’d been expecting my footsteps all day. “New to the castle, are you? Or new to being brave?” I swallowed. “Both, sir.” A faint smile touched the corner of his mouth. “Good. Brave comes easier when it’s hungry. Come—before night work begins. The stablehands will tell you chores, but they won’t tell you rules.” He nodded toward the courtyard where torches were being lit. “And rules, squire, are what keep you alive long after you’ve forgotten your fear.” </nc-section> <nc-section data-title="Version 2: Sir Roland’s Questions" data-color="green"> The stable doors clapped shut behind us with a final, authoritative sound. Thunder stamped once, restless, and I guided him into his stall. I hadn’t even finished looping the saddle strap when a shadow filled the doorway—tall, armored, and impatient with greetings. “Frederick,” said a voice that didn’t need volume to command attention. I turned. Sir Roland stood with one gauntlet folded across his chest, the other hand resting near the hilt of his sword in a way that suggested he rarely needed to draw it. His armor was scuffed like a road-worn traveler’s boots, and his cloak hung heavy with the damp of evening. He studied me the way a rider studies a horse’s legs—quietly, precisely, looking for weakness before trouble arrives. “Tell me something,” he said. “When you first saw the castle, did you think of glory—or did you think of escape?” Heat rushed up my neck. “Glory, sir. And—later—escape. When I realized I’d have to earn the right to stay.” Sir Roland’s gaze softened only a fraction. “Earn it, then. Training starts tonight. Not with swordplay. With discipline.” He pointed toward a stack of hay and a bucket of water set too far from the trough. “Go on. Move it. Slowly. Correctly. The castle will forgive you mistakes—but not carelessness.” </nc-section> <nc-section data-title="Version 3: A Knight Tests the New Squire" data-color="blue"> The stables were still busy though the day was dying—hooves scraping, bridles clinking, men murmuring to one another in low, practical tones. I tried to look like I belonged there. Thunder snorted as if he, too, were judging my posture. That was when Sir Roland appeared, stepping into the yard as though the earth had made room for him. He carried himself with the calm of someone who’d already measured every risk and found them survivable. His cloak bore the faint scent of rain, and a thin chain of keys hung at his belt with the authority of a magistrate. He didn’t ask how I was. He looked at my hands—at the way my fingers still hovered near my cloak as if searching for an anchor. Then he looked at Thunder. “Your mount respects you,” Sir Roland said. “That’s a start.” “I—thank you, sir,” I managed, though my throat felt dry. Sir Roland approached the water trough and rapped the rim once with his knuckle. The sound rang clean. “You’ll learn quickly here,” he said, voice measured. “Because the castle does not suffer fools for long. Tell me, Frederick—have you ridden in storms?” “Yes, sir. A little.” “A little,” he repeated, as if weighing the word. Then he nodded toward the far end of the yard, where a lantern had been left unlit. “Then you know what it feels like when the world goes dark without warning.” His eyes met mine. “Tonight, you’ll prove what you can do when the next darkness comes. With work first. With attention always.” </nc-section>
