<nc-section data-title="Version 1: The Knight at the Stables" data-color="red"> Thunder slowed as we reached the stables, hooves striking damp earth that still held the day’s heat. The air smelled of straw, leather, and something sharp—oiled metal. A stableboy hurried past, nearly colliding with my reins, then hurried again, as if the castle itself had sharp edges. From the shadow of the feed shed stepped Sir Roland, local knight and instructor for hopeful squires. He wore armor that looked too heavy to be casual, yet he stood with an ease that made it seem like the steel belonged to him the way skin did. His surcoat bore the kingdom’s crest, stitched in thread so dark it looked almost black until the torchlight caught it. “Frederick,” he said, as though tasting the name. His voice was roughened by smoke and winter air. “So you’re the one they sent.” I dismounted, bowing the way my master had drilled into me. “Sir Roland. I’m ready to begin my training.” Sir Roland’s gaze moved over me—boots, hands, posture—taking inventory with the precision of a master armorer. “Ready,” he echoed, and the word sounded both approving and doubtful. “Good. Then let’s see if you can keep up before the castle decides you’re only in the way.” He gestured toward the stable door. “Start by tending Thunder. If you can earn the trust of a beast, you’ll learn the rest faster than most.” </nc-section> <nc-section data-title="Version 2: A Test in Leather and Breath" data-color="green"> By the stables the world changed sound—less galloping wind, more clop and clink, more the muffled sigh of horses settling into evening. Thunder blew a warm cloud against my sleeve as I led him under the lanterns. That’s when Sir Roland appeared, as quietly as a closing gate. He approached with no flourish, no trumpet—just the steady, unavoidable presence of a man used to being obeyed. His mail caught the light in small, restless flashes, like a reflection that wouldn’t hold still. “Careful,” he warned, watching my hands as I tied the knot. “Horses remember the ones who rush them.” I straightened quickly. “Sir Roland.” He nodded once, as if I’d passed an invisible inspection. “A squire’s first lessons aren’t about swords. They’re about patience and keeping promises.” His eyes flicked to Thunder’s eye, calm and watchful. “You’ve brought him well. That’s something.” Then Sir Roland’s expression sharpened—subtly, like a blade being drawn a fraction of an inch. “And now you’ll do one more thing: listen.” He stepped closer to the stable wall, where the night air threaded through gaps in the stone. I heard nothing at first—only the horses’ breathing and the distant clatter of late preparations. But Sir Roland tilted his head. “Do you hear it?” he asked. I strained. Beneath the ordinary sounds, there was another rhythm: faint, irregular, as though something far away was knocking—patiently—against the world itself. </nc-section> <nc-section data-title="Version 3: The Welcome That Meant Trouble" data-color="blue"> The castle’s main yard gave way to the stables’ quieter kingdom—wooden beams, iron latches, and rows of horses standing like dignified statues while they waited to be needed. Thunder’s mane shimmered with lantern light, and his ears twitched at every movement. Sir Roland stepped out from between two stall doors, tall enough that I had to tilt my chin to meet his eyes. He looked like someone carved from old duty: a scar on one cheek, weathered but not softened, and a gaze that could pin a liar to the floor. “Frederick,” he greeted, and the name traveled through the stable like a command. “So you made it.” “Yes, Sir Roland.” My throat felt dry. I had imagined his arrival in a grand hall. Instead, it was straw underfoot and the steady scent of horse sweat. Sir Roland ran a gloved thumb along the rim of Thunder’s feed trough—an absent gesture, but it bought him time to assess me. “They say you’re eager,” he said at last. “Eagerness is useful. But eagerness without sense gets boys hurt.” I opened my mouth to protest, then closed it again. Training had taught me that the first lesson was knowing when silence was smarter than speech. Sir Roland’s mouth tightened, almost a smile, almost a warning. “Tomorrow you’ll carry water. After that, you’ll learn to clean a blade until it shines like truth. And if you’re wise, you’ll keep your eyes open even when no one is watching.” His gaze drifted past me toward the castle’s darker edge, where the shadows pooled thicker than they should have. “Because tonight,” he added quietly, “I don’t like the way the wind sounds over the towers.” </nc-section>
