<nc-section data-title="Version 1: The Iron Courtesies" data-color="red"> Frederick reined Thunder in beside the stables, where the air smelled of straw, leather, and honest sweat. Horses stamped and tossed their heads as the gate creaked behind him. “A new face,” came a voice like hammered steel. Sir Roland—broad-shouldered beneath his polished armor, scar running pale across one brow—strode toward the tack room with the slow certainty of a man who expected doors to move aside for him. His gauntlets were still dusted with stable grit, as if he’d been tending a mount moments before Frederick arrived. “You there,” Sir Roland said, pointing without looking. “Frederick, isn’t it? The king’s clerk wrote my name on the training roster, but I didn’t believe it until I saw you walk in.” Frederick gave a hesitant bow, his boots scraping the packed earth. “Sir Roland. I—yes, sir. I’m here to begin training.” Sir Roland’s gaze traveled over him—over the newness of his armor, the careful way he held himself, the lack of callus at his hands. “Good. New hands mean you haven’t learned bad habits yet.” He let the words hang like a blade offered for inspection. “First lesson: the stable teaches more truth than the training yard. Your horse is not your burden. It’s your partner—treat it poorly and it will teach you failure.” Thunder flicked an ear, sensing the knight’s authority, and snorted softly as if in agreement. Sir Roland clapped him once on the flank, hard enough to remind the stallion who commanded the space. “Come. We’ll start with greeting your mount properly. Then we’ll talk about whether you’re fit to hold a sword without flinching.” </nc-section> <nc-section data-title="Version 2: Oaths by the Haystack" data-color="green"> By the stables, twilight had gathered in smoky layers between the beams, turning every drifting mote of dust into something almost magical. Frederick led Thunder toward the nearest stall and began the familiar work of easing the saddle straps free—an action that felt like both relief and nervous ceremony. “Easy,” a voice called, warm as bread and just as grounding. Sir Roland appeared at the far end of the aisle, walking with the unhurried steadiness of a man who had learned that patience was a kind of strength. His sword hung at his side, sheathed, but the way he carried himself made it clear that it wasn’t truly resting. He raised a hand in greeting. “You’re Frederick. The boy the castle is trying to turn into a knight.” His eyes crinkled at the edges, as if he found the idea both amusing and necessary. “Well then—show me your manners.” Frederick startled, then straightened. “Sir Roland!” he said, more loudly than he intended. He bowed too quickly, nearly banging his head on the saddle frame. Sir Roland chuckled once, not unkindly. “Careful. Steel remembers clumsiness.” He stepped closer and examined Thunder as though reading a map. “That stallion will forgive a lot, but not disrespect.” He gestured toward the horse’s tack. “Untie him properly. Then—if you want training—you’ll speak your thanks aloud. Even horses know when a man is lying with his silence.” Thunder’s tail swished, impatient, yet when Frederick loosened the straps with care, the stallion lowered his head, accepting the moment. Frederick cleared his throat. “Thank you,” he said, surprising himself with how sincere it sounded. Sir Roland nodded. “Good. Now we begin. The first oath is not to the crown.” He leaned in slightly, voice lowering. “It’s to the work. The second oath is to courage—when fear arrives, you keep doing the right thing anyway.” </nc-section> <nc-section data-title="Version 3: The Knight’s Measure" data-color="blue"> Frederick turned from the castle yard toward the stables, hoping the clatter of hooves would drown out his nerves. Thunder followed willingly, but his own brightness—his eager posture, his flicking ears—only made Frederick feel more exposed in this place of banners and watchful eyes. A man in bright armor waited near the manger, as though the stable itself had summoned him. Sir Roland’s presence filled the space without effort: not just size and steel, but a calm that pressed against the air like a shieldwall. “You’re late,” Sir Roland said at once. Frederick’s cheeks flamed. “Sir—no, I arrived as—” He faltered, unsure whether the knight meant literal lateness or the deeper kind: the lateness of being unready. Sir Roland lifted a finger, silencing the apology before it could become a tangle. “I did not say you were wrong. I said you were late.” He stepped aside so Frederick could see the stall, the clean grooming kit, the water bucket set just so. “This castle measures time by preparation, not by clocks.” Frederick swallowed. “Then… how should I prepare?” Sir Roland’s gaze moved to Thunder, then back to Frederick’s hands. “Start by learning what your arms can do without help.” He pointed to the grooming tools. “Clean. Brush. Check the hooves. If you can’t give attention to small things, you’ll fail at the large ones when they matter.” He reached into a pocket and produced a narrow strip of leather—unadorned, worn at the edges. “And when you finish, you’ll bring me that strap. Not for show. For testing.” Frederick stared. “Testing, sir?” “For whether you flinch,” Sir Roland replied, simple as a command. “Some men fear pain. Others fear being judged. The sword punishes both.” Thunder nudged Frederick’s shoulder, grounding him. “I won’t flinch,” Frederick said, even though the words trembled. Sir Roland regarded him for a long moment, then nodded once—approval given sparingly, like good coin. “Then prove it. Begin.” </nc-section>
