<nc-section data-title="Version 1" data-color="red"> Passing beneath the heavy iron portcullis, the rhythmic clatter of Thunder’s hooves echoed loudly against the cobblestone courtyard. I guided him toward the sprawling timber stables on the eastern wall, my muscles aching from the three-day ride. Before I could dismount, a towering figure stepped out from the shadowed archway of the stables, wiping his hands on a coarse rag. Even without his full plate armor, the man commanded an undeniable presence. Broad-shouldered, with a jagged scar splitting his left eyebrow and a beard streaked with silver, he looked every bit the hardened veteran. "Whoa there, boy," the man murmured, catching Thunder's bridle with a practiced, gentle hand. His sharp grey eyes shifted up to evaluate me. "You must be Frederick. Word from the borderlands said you’d arrive before nightfall." I quickly swung my leg over the saddle and dropped to the stones, bowing my head respectfully. "Yes, my lord. Reporting for squire duties." A gruff bark of laughter escaped him. "Save the 'my lords' for the pampered nobles in the great hall, lad. I am Sir Roland. Around here, we work for our keep." He patted Thunder's neck approvingly. "You kept your mount in fine shape despite the hard road. That speaks well of you. Stable him, grab your gear, and meet me in the armory. Your training begins tonight." </nc-section> <nc-section data-title="Version 2" data-color="green"> The scent of hay, leather, and woodsmoke washed over me as I brought Thunder to a halt near the castle stables. My heart hammered against my ribs—partly from the exhilarating gallop, and partly from the sheer nerves of finally being here. "A fine beast! A bit heavy on the forehand when he's tired, I wager, but a magnificent stride!" The booming voice startled me. Walking briskly toward us was a knight clad in gleaming half-plate over a tunic bearing the royal crest. He had a mop of unruly auburn hair, a wide, welcoming grin, and a greatsword strapped casually to his back. I scrambled off Thunder, nearly catching my boot in the stirrup, and offered a hasty salute. "Good evening, Ser. I am Frederick of Oakhollow." "Ah, the new squire! Welcome, welcome!" The knight clapped a heavy, gauntleted hand onto my shoulder, nearly driving me an inch into the dirt. "I am Sir Roland. I was just checking on my own mare when I saw you tearing across the plains like a bat out of the hells. Thought the dragons had returned for a moment!" He winked, instantly putting my racing heart at ease. "Come, let's get Thunder some oats and water, and I'll show you to the barracks before the cooks lock up the hot stew." </nc-section> <nc-section data-title="Version 3" data-color="blue"> As the massive oak gates groaned shut behind me, the warmth of the setting sun vanished, swallowed by the looming shadows of the castle walls. I led Thunder toward the stables, the sudden quiet of the courtyard making me feel small and out of place. The metallic rasp of a whetstone sliding against steel broke the silence. Sitting on an overturned barrel by the stable doors was a knight. He wore darkened chainmail and a weathered cloak, his focus entirely consumed by the longsword resting across his knees. I dismounted slowly, leading Thunder forward. "Excuse me, Ser?" The sharpening stopped. The knight looked up, his gaze as cold and piercing as the blade in his hands. Shadows hollowed his cheeks, and when he stood, he moved with the silent, lethal grace of a stalking wolf. "Frederick," he stated. It wasn't a question. "Yes, Ser." "I am Sir Roland," he said, sheathing his sword with a sharp *clack*. He walked a slow circle around me and Thunder, inspecting the mud on my boots, the fray on my traveling cloak, and the sweat lathering my stallion's flanks. "The last squire they sent me lasted three weeks before he cried for his mother. These are dark times, boy, and this castle does not forge ceremonial knights. We forge survivors." He gestured toward an empty stall with his chin. "Tend to your horse. If you aren't in the yard in ten minutes, you sleep in the mud." </nc-section>
