<nc-section data-title="Version 1: Sir Roland’s Welcome" data-color="red"> I reined Thunder in beside the stables, where straw steamed faintly in the evening chill. The air smelled of oats, iron, and honest work. Before I could dismount, a heavy silhouette stepped into the lamplight—armor scuffed by travel, yet polished where it mattered. “Frederick,” said the local knight, Sir Roland, as if my name had been carved into the cobbles. His visor was lifted, revealing a weathered face and eyes the color of stormclouds. “You’re late.” “I arrived at dusk, sir,” I managed, tightening my grip on the reins. Thunder snorted, impatient with my nerves. Sir Roland’s gaze flicked to my hands—young, pale, not yet callused into a warrior’s grip. “Dusk is a time for shadows,” he said. “And shadows hide mistakes. Come—before the horses learn you’re afraid of them.” He gestured toward the tack room. My boots scraped the stones as I followed, feeling the weight of scrutiny settle on my shoulders like a cloak. </nc-section> <nc-section data-title="Version 2: The Knight’s Test" data-color="green"> Near the stables, I found Sir Roland watching the horses the way a poet watches ink—patiently, with certainty that something would reveal itself. He stood half-turned, one gauntleted hand resting on the pommel of his sword. The leather of his gloves had been worn smooth by years of practice. “You,” he called, voice carrying over the clink of harness. “Squire Frederick.” I hurried over, uncertain whether to bow or simply apologize for existing. “Sir Roland. I—” “Good,” he interrupted, and the word landed like a gate closing. “You’re here. That’s step one.” He crouched and lifted a loose strap from the tack bench, examining the knot as though it were a wound. “Listen carefully. A stable is a battlefield that runs on routine. If you tie poorly, you endanger lives without ever drawing steel.” I nodded, swallowing my fear. Sir Roland handed me the strap. “Show me you can follow instruction. Then we’ll see whether you can learn quickly.” </nc-section> <nc-section data-title="Version 3: Oaths by the Stable Door" data-color="blue"> The stables’ lanterns burned with a steady, honeyed light, and the horses shifted in their stalls like living hearths. I led Thunder toward the feed trough, but I hadn’t taken two steps before I felt the quiet attention of someone trained to find trouble. Sir Roland appeared by the stable door, cloak damp at the hem as though he’d been out in rain that hadn’t reached the rest of the yard. His armor creaked softly when he moved, a sound that made my spine straighten. “So,” he said, looking me over with the calm severity of a judge. “The kingdom sends a new blade to the last dragon’s lessons.” My throat tightened. I’d heard rumors—whispers that the dragon was not merely a story, but a reckoning waiting to happen. “Sir Roland,” I replied, forcing steadiness, “I’m ready to be trained.” “Ready,” he repeated, letting the word hang. Then he stepped closer, close enough that I could smell oil and horse sweat beneath the sharpness of steel. “Then stand where you can see the stables’ exits. Because a squire who can’t watch for danger will become danger’s errand boy.” And with that, Sir Roland reached past me, opened the stable door, and beckoned as if the night itself were already marching. </nc-section>
