<nc-section data-title="Version 1: A Stern Welcome" data-color="red"> Passing beneath the heavy iron teeth of the portcullis, I guided Thunder across the bustling cobblestones toward the sprawling wooden stables. Before my boots even touched the dirt, a shadow fell over me. A tall, broad-shouldered man stepped out from the stable archway, wiping grease from his gauntlets with a rag. A jagged scar split his greying eyebrow, and his steel-blue eyes appraised me with little warmth. "You're late, boy," he growled, his voice like grinding stones. "The sun's nearly down. A squire of this keep rises before the light and beds down only when his master's steel is spotless." I swallowed hard, straightening my spine as I dismounted. "Forgive me, ser. The roads from the valley were—" "Excuses don't turn a blade," he interrupted, tossing the rag aside and stepping closer to inspect Thunder's heaving flanks. "I am Sir Roland. Rub down your mount, see him fed, and report to the barracks. Your training begins tonight." </nc-section> <nc-section data-title="Version 2: A Boisterous Greeting" data-color="green"> The courtyard smelled of woodsmoke, roasted mutton, and damp earth. I reined Thunder to a halt near the warm lantern-glow of the stables, my muscles aching from days in the saddle. Almost immediately, a booming laugh echoed from within the stalls, and a mountain of a man strode out to meet me. He wore a tabard faded from years of sun and rain, and a thick braided beard rested against his barrel chest. "Hah! Look at the size of that stallion!" the man bellowed, clapping a heavy, calloused hand affectionately against Thunder's neck. The horse snorted, surprisingly calm under the stranger's touch. Dark, twinkling eyes turned up to meet mine. "And you must be young Frederick. Welcome to Highkeep, lad! I'm Sir Roland." "An honor, Sir Roland," I said, sliding down from the saddle and offering a crisp bow, just as my father had practiced with me. Roland waved a dismissive hand, grinning broadly. "Save the courtly bows for the lords in the high tower. Down here in the mud, we judge a man by his grit and his sword-arm. Come, let's get this magnificent beast some oats, and we'll see about finding you a warm supper." </nc-section> <nc-section data-title="Version 3: The Quiet Measure" data-color="blue"> I slowed Thunder to a trot as we passed through the outer bailey, following the scent of fresh hay and leather toward the stables. The evening air was growing crisp, and the courtyard was emptying as servants hurried indoors. Near the water troughs sat a lone figure on an overturned crate, methodically running a whetstone down the edge of a bastard sword. Shkeen. Shkeen. The rhythmic sound stopped as I dismounted. The knight looked up—a lean, weathered man with silver threading his dark hair and a tunic bearing the crest of thesilver hawk. "You rode him hard across the flats," the man observed quietly, nodding toward the white foam gathering at Thunder's neck. "Brave, for a boy eager to reach his post. Foolish, if an ambush had been waiting at the treeline with your mount winded." Heat rose to my cheeks, and I bowed my head. "I didn't think of that, ser." The knight stood, sliding his blade smoothly into its scabbard. A faint, approving half-smile ghosted across his lips. "Good. An honest answer is better than a proud lie. I am Sir Roland, Master-at-Arms. Walk your horse until his breathing slows, Frederick. Lesson one is already underway." </nc-section>
