<nc-section data-title="Version 1: Sir Roland’s Challenge" data-color="red"> Before I could dismount, a shadow fell across the cobbles. A knight strode from the stable yard in gleaming armor, the kind that seemed to drink the fading light. Sir Roland—broad-shouldered, silver-bearded, and sharp-eyed as a falcon—raised a gauntleted hand in greeting. “Frederick, is it?” he called, voice carrying over the clop of hooves and the soft snorts of horses. “You’re late enough that I’d think you were hunting trouble instead of training.” My stomach tightened. “I—no, sir. The road—” He cut me off with a courteous inclination of his head. “Enough excuses. A squire’s first lesson is not speech, but readiness.” With a jerk of his chin, he indicated the yard as if it were a battlefield. “Show me you can handle yourself. One pass. Straight spear-ward. Then we’ll see to your lessons.” I swallowed my nerves, checked my grip on my training spear, and stepped forward while Sir Roland circled like a measuring sword. His gaze was heavy, but not cruel—more like a smith’s, assessing flaws in raw iron. “Good,” he said after my stance held firm. “Now don’t let the castle convince you you’re safe. The stables smell sweet, but danger always hides where you’re least watching.” </nc-section> <nc-section data-title="Version 2: The Master of the Yard" data-color="green"> At the edge of the stables, where the straw steamed faintly in the evening heat, Sir Roland waited as though he’d been there all along. His armor bore the quiet polish of constant use, and his cloak hung with the weight of authority. When I approached, he bowed—not dramatically, but with the measured respect of a man who knew exactly how far manners should go. “Frederick,” he said, tasting my name like it mattered. “Welcome to the castle’s backbone.” Behind him, horses stamped and shifted, their tack chiming softly. The air smelled of hay, iron, and leather oil. I realized, with a sudden shame, that I’d been expecting someone grander—someone who would greet me with speeches and blessings. Instead, Sir Roland’s attention was practical, focused on the work that kept the realm upright. “I’ve seen your letters,” he continued. “Good hand. Steady manners. But papers don’t stand you on a saddle when the wind turns mean.” He gestured toward the training posts near the feed trough. “Can you mount without staring at the ground?” “Yes, sir,” I answered too quickly. “Then do it,” Sir Roland replied simply. I swung up onto Thunder’s back, trying to appear effortless while my nerves begged to be honest. Sir Roland watched my shoulders, then my feet—every detail. “Better,” he said, and the word warmed something in my chest. “Come. You’ll begin with ground work and stable discipline. A knight who can’t command a horse can’t command a battlefield.” </nc-section> <nc-section data-title="Version 3: A Warning in the Air" data-color="blue"> The stables were alive with small sounds—brushes scraping, doors creaking, a distant clatter of harness—until Sir Roland’s arrival changed the rhythm. I heard it first: boots striking stone with purpose, a silence following close behind as if the yard itself listened. He stood near the central stall, one hand resting on the hilt of his sword, the other holding a folded strip of parchment. His eyes flicked from my face to my travel-worn cloak to the spear I carried like an apology. “Frederick,” he said, solemn enough that even the horses seemed to breathe quieter. “I’m Sir Roland. I look after the men who arrive with courage and those who arrive with doubt.” My throat felt dry. “I’m here to learn, sir.” “Then learn this,” he said, lifting the parchment just slightly. The seal bore the mark of the royal order. “There’s talk in the villages beyond the outer fields—talk of a presence that doesn’t belong to any of our stories.” My pulse quickened. “A dragon?” Sir Roland didn’t confirm it. He only stared past me for a moment, as if listening to something beneath the stable’s ordinary noises. “Not every tale arrives with smoke. Some arrive with warnings.” He lowered the parchment and pointed toward the training yard. “Before your lessons begin, you’ll practice vigilance. Two rounds. No mistakes, no hesitation—because if danger comes, it won’t announce itself politely.” I exhaled and stepped forward, steadier now. The castle gates had been stone and iron, but Sir Roland’s voice made the air feel thinner—like the world was holding its breath. </nc-section>
