<nc-section data-title="Version 1: The Knight by the Stables" data-color="red"> The air near the stables smelled of straw, sweat, and sweet oats, and it was there—between the whisper of saddle leather and the clop of hooves—that Sir Roland found me. He stood with the easy authority of a man who didn’t need to raise his voice to be heard. His armor caught the last light of day, turning every edge and rivet into a small blade of gold. “Frederick,” he said, as if he’d been expecting me since before I’d learned the name, “you’re late.” My stomach tightened at the words, but I bowed anyway, the motion practiced in the dark corners of village halls. “Forgive me, Sir. The road was—” “Bumpy enough to test a man’s patience,” he finished, stepping closer. His gaze moved over me the way a smith assesses iron. “Still, you made it. That’s the first lesson.” One hand lifted, gesturing toward the horses. “If you mean to train here, you’ll learn quickly: no grand heroics until the stable is clean, no sword practice until the tack is sound. Start by brushing Thunder until he looks like a sunrise.” I blinked. “My… my horse, sir?” Sir Roland’s mouth twitched, almost a smile. “My mistake, squire. You wouldn’t be bringing a beast of that temper unless you planned to earn its trust.” </nc-section> <nc-section data-title="Version 2: A Test in Silence" data-color="green"> By the time I reached the stables, the castle sounds had faded into a deeper quiet—only the horses breathed, slow and steady, and the lanterns swayed like cautious stars. I led Thunder into the nearest stall, tightening the strap by habit, when a shadow fell across the straw. Sir Roland stood there, tall even among the height of the rafters. His cloak hung in disciplined folds, and his gauntleted hand rested on the hilt of his sword as though it were simply part of his anatomy. “You keep your grip steady,” he observed, watching my fingers as I worked. “Good. Men who fidget cut themselves.” “I’m Frederick, sir,” I managed, though my voice felt small beside the clang of armor. He nodded once. “Yes. The steward told me a newcomer would arrive today. I expected someone older, but expectation is a foolish thing.” His eyes flicked to Thunder, then back to me. “Tell me—why did you come?” The question struck like a dropped hammer. I looked at my horse, at the calm, dark eye that seemed to wait for my answer. “Because I was chosen,” I said, not sure if I meant it, or if it was merely what I’d been told. Sir Roland’s expression sharpened—not cruelly, but with the clarity of a blade being drawn. “No. Chosen means you have something worth taking. But taking is different from earning. Earn it.” He turned slightly, indicating the rows of tack and brushes. “Now. Brush the horse. Then—when the stable boy is free—run the errands you’re assigned. A knight is a promise. Begin by keeping yours.” </nc-section> <nc-section data-title="Version 3: The Sir’s Warning" data-color="blue"> The stables were warm enough to soften cold thoughts, yet my shoulders stayed tight. Thunder shifted in his stall, stamping once as if impatient with my nerves. I had just begun to loosen the saddle when Sir Roland stepped from the shadow of the main aisle. He smelled faintly of steel and pine smoke. His presence was a kind of weather—quiet, unavoidable, and somehow already there before I noticed it. “Easy,” he said, though he was speaking to me, not the horse. “You’re handling him like he’s a sack of grain. Thunder isn’t grain. He’s a conversation.” I swallowed, then tried again, gentler this time. “Sir Roland,” I said, catching up my courage as one catches a falling strap. “Thank you for meeting me.” “Meeting?” he repeated, amused, and the sound of it was like a coin turning in a pocket. “I’m not here to be polite. I’m here to see whether you can be useful.” He moved to the stall door, leaning one elbow on the frame. “Listen carefully, Frederick. Training starts now, and it won’t wait for you to feel ready. If you neglect the basics, you’ll blame instructors. If you neglect the basics, you’ll blame the castle. But the truth is simpler.” His eyes met mine. “You’ll blame yourself—for believing you were too important to learn slowly.” Thunder let out a soft snort, as if agreeing. Sir Roland nodded toward the brush in my hand. “Go on, squire. Show me you can pay attention. Then we’ll talk about swords. After.” </nc-section>
