<nc-section data-title="Version 1: The Knight at the Stables" data-color="red"> Thunder’s hooves slowed from a gallop to a steady clatter as I passed beneath the castle gate. The courtyard beyond was alive with evening noise: servants carrying baskets, guards changing watch, and stablehands calling to one another over the whicker of horses. Near the stables stood a broad-shouldered knight in a weathered blue cloak. His armor bore scratches that no polishing cloth had managed to hide, and a silver wolf shone upon his breastplate. “You must be Frederick,” he said before I had even swung down from the saddle. I stiffened. “Yes, sir.” The knight’s stern face softened into the hint of a smile. “Sir Roland, master of arms for this keep. And unless your horse has learned to speak, I suspect this is Thunder.” Thunder tossed his mane, as if pleased to be recognized. Sir Roland stepped closer and ran an experienced eye over the stallion’s tack. “Fine animal. A squire who arrives with a horse like this has either been well trained—or very fortunate.” “I hope to be well trained,” I replied. “Good answer.” Sir Roland offered his hand, armored fingers closing firmly around mine. “Then come. The castle has many lessons to teach, Frederick. Some of them are kinder than others.” </nc-section> <nc-section data-title="Version 2: Sir Roland’s Measure" data-color="green"> By the time I reached the stables, the last edge of sunlight had vanished behind the western hills. Lanterns burned beneath the eaves, throwing gold across the straw-strewn yard. A knight waited beside the stable doors, one hand resting on the hilt of a sword. He was not dressed for ceremony. His mail was dark with travel dust, and an old scar cut across his chin. Yet he carried himself with such quiet certainty that even the stablehands gave him a wide berth. “Frederick,” he called. I drew Thunder to a halt. “Sir?” “I am Sir Roland.” His gaze moved from my face to my worn riding boots, then to the practice sword strapped at my side. “Your father’s letter said you were eager.” “Yes, Sir Roland.” “Eagerness is useful,” he said. “But it can get a boy killed if it is not accompanied by patience.” The words struck harder than I expected. I slid from Thunder’s back and bowed my head. “Then I will learn patience.” For the first time, Sir Roland smiled. “We shall see. Give your horse to the groom. Tomorrow at dawn, report to the eastern yard. Bring your sword—and leave your pride in your chamber.” As Thunder was led away, I watched Sir Roland disappear into the stable shadows, wondering what kind of knight spoke of death as plainly as the weather. </nc-section> <nc-section data-title="Version 3: A Welcome Beneath the Banners" data-color="blue"> The stable yard lay just beyond the main courtyard, sheltered by a long stone wall covered in climbing ivy. Thunder snorted eagerly at the scent of hay, and I laughed despite the ache in my legs from the long ride. “Well met, young rider.” I turned to find a knight approaching from beneath the hanging banners. He was older than I had imagined a great warrior would be, with silver beginning to thread through his dark hair. A deep blue cloak fell from his shoulders, fastened by a brooch shaped like a dragon’s wing. “Sir Roland?” I asked. “The same.” His voice was warm, though his eyes missed nothing. “I have been expecting you since noon. Your arrival was delayed.” “The river road was washed out,” I explained. “Thunder found a path through the hills.” Sir Roland looked admiringly at the stallion. “Then Thunder has already proved his worth.” He reached up to stroke the horse’s neck, and Thunder, who usually distrusted strangers, stood perfectly still. “You are welcome at Castle Ardent, Frederick,” the knight said. “You will serve, you will train, and if you possess the courage I have heard whispered of, you may one day wear spurs of your own.” My heart beat faster at the thought. Then Sir Roland’s expression grew grave. “But first, there is something you should know. Strange signs have appeared in the northern mountains. And in this kingdom, a squire’s lessons rarely remain inside the training yard.” </nc-section>
