<nc-section data-title="Version 1: Sir Roland’s Welcome" data-color="red"> The moment Thunder’s hooves struck the packed earth by the stables, a man in burnished mail stepped from the shadow of the hayloft as if he’d been waiting for my arrival all along. Sir Roland—hard-eyed, broad-shouldered, his surcoat crested with the stag of the border—raised a gauntleted hand in greeting. “Frederick,” he said, testing the name like a blade for balance. “You’re late enough to be nervous, early enough to be useful.” I swung down awkwardly, boots thudding. My breath puffed in the cooling air. “Apologies, sir. The road—” “I don’t care for excuses,” he interrupted, then softened by a fraction. His gaze flicked past me to Thunder. “Only for effort. Come. We begin where boys always think they’re done—cleaning the gear.” A stable boy was already hovering with a bucket. Sir Roland took my reins without asking, then handed me a leather strap as though it were a lesson in itself. “Hold this steady. If you can’t keep your hands from shaking, you’ll never keep a lance from drifting.” My fingers closed around the strap. It felt warmer than it should have, as if the old hide remembered countless battles. </nc-section> <nc-section data-title="Version 2: The Test at the Stable Door" data-color="green"> Near the stables, the evening smelled of straw and horse-sweat, honest scents that made my nerves seem foolish. I had barely finished leading Thunder to a stall when a voice cut through the bustle—low, commanding, and oddly calm. “Frederick.” I turned to find Sir Roland at the threshold, one gauntlet resting on the doorframe. His armor caught the last light like a promise. He didn’t smile, but his eyes crinkled at the edges the way a practiced storyteller’s might, as if he’d seen a hundred first days and knew exactly how they ended. “You’ll find,” he said, “that knights are made in small, unglamorous moments. Today’s moment is this: you will not start training by trying to impress me.” He motioned toward a rack of bridles and polishing cloths. “Lest you think I’m cruel, I’ll tell you why. If you can’t care for a horse you can see, you won’t be trusted with the men you’ll one day ride alongside.” Thunder stamped once, impatient. I swallowed and set to work—brushing grime from leather, checking buckles, straightening straps until everything lay true. When I looked up again, Sir Roland was watching quietly, as if measuring not my strength, but my steadiness. “Good,” he finally said. “Now come. I want you to meet the sword that will teach you humility.” </nc-section> <nc-section data-title="Version 3: A Knight’s Shadow, a Dragon’s Echo" data-color="blue"> The stableyard was a pocket of dusk, hemmed in by stone and the quiet thunder of wings somewhere far overhead. As I guided Thunder between the posts, a figure stepped out from beside the feed barrels—tall, cloaked in shadow, and wearing authority the way other men wore weather. Sir Roland inclined his head. “Frederick.” His voice carried the weight of practice, the kind spoken after many days when promises had to hold. He studied me from my boots to my brow, and in that scrutiny I felt myself becoming something like a tool—either fitted properly, or discarded. “You’ve come to learn,” he said, “but learning begins with listening. That stable’s a louder teacher than you think.” Before I could ask what he meant, he tapped the side of my saddlebags. “You’re carrying something you shouldn’t have brought without orders.” My throat tightened. I reached in reflexively, and my fingers brushed cold metal. Not a weapon—at least, not a common one. A small, worn scale, no bigger than a fingernail, tied beneath the lining with twine so old it had nearly fused to the cloth. Sir Roland’s gaze sharpened. For the first time, the calm on his face cracked—just enough for a spark of something dangerous to show. “Where did you find that?” “I—on the road,” I stammered. “It was caught in the roots of a fallen tree.” Sir Roland exhaled slowly, as though restraining a storm. “Then you’re not only late, Frederick. You’re already tangled in the story we swore to avoid.” He lifted his chin toward the stables’ far end, where the lanterns burned dimmer. “Come. Training starts now—and so does the truth.” </nc-section>
