<nc-section data-title="Version 1: Red - Steel at the Stable Door" data-color="red"> The castle’s stables came into view—long wooden stalls under tiled roofs, all of it smelling of straw, sweat, and iron-shoed promise. Thunder stamped as the gate latched behind me, and I slid from the saddle with more hurry than grace. A heavy hand clapped my shoulder. “Easy, boy. Heroes don’t jog—*they arrive*.” The voice belonged to Sir Roland, the local knight, broad as a gatehouse and weathered as the stones. His surcoat bore the same crest I’d seen on the castle banners, though his eyes looked sharper than any painted emblem. He nodded toward Thunder. “Name him properly and he’ll learn you. Spoil him and he’ll buck you in front of everyone.” Then, with the patience of a man who had taught many hands what not to do, Sir Roland gestured toward the tack room. “Come. You’ll start where most squires fail—care. The blade is only half the lesson.” </nc-section> <nc-section data-title="Version 2: Green - Courtesy Before Blades" data-color="green"> By the time I reached the stables, dusk had softened the world into a muted hush. Lanterns had begun to glow along the posts, turning the straw gold. Thunder snorted and leaned into my side as if relieved I’d finally brought him somewhere he could breathe. “Frederick,” came a calm voice from near the manger, spoken like a question already answered. I turned and found Sir Roland waiting there—helmet under one arm, gauntleted fingers folded as though he were at prayer. There was nothing hurried about him, nothing theatrical. He greeted me the way an experienced craftsman greets a new apprentice: with a ledger of expectations and a measure of trust. He looked past me to my saddle, then to my hands. “You’ve got the right sort of nervous,” he said, as if that were a badge earned. “Listen closely: a knight’s first weapon is respect—first for men, then for beasts, and only afterward for steel.” Sir Roland motioned me toward a bucket and grooming brush. “We begin with what you can’t rush. Tend him well. Then we’ll see what’s left in you after the work.” </nc-section> <nc-section data-title="Version 3: Blue - A Knight’s Warning in the Night Air" data-color="blue"> The stables swallowed sound—hoofbeats dampened, voices softened, even the crackle of lantern wicks seemed to hold its breath. I was tightening Thunder’s reins when someone stepped into my shadow, silent enough that I nearly startled. “Careful,” Sir Roland rumbled, low and steady. He didn’t draw attention by raising his voice; he drew it by simply being unavoidable. His armor was immaculate in the way of practiced hands, yet his gaze was not polished—his eyes were watchful, as though he’d seen too many bright starts end in scraped knuckles and broken pride. He circled the stall once, assessing, then came to stand at my shoulder. “You’re late,” he said, and when I looked uncertain, he amended it with a grim half-smile. “Late by a minute. Early by intention. That’s better than most.” Sir Roland leaned in slightly, as if speaking a secret to the horse as much as to me. “This castle keeps order. The yard keeps lessons. You’ll learn both. Now—show me how you mind your beast before you ask the beast for anything.” </nc-section>
