<nc-section data-title="Version 1" data-color="red"> Near the stables, the smell of hay and warm horses drifted through the cooling evening air. Frederick had barely swung down from Thunder’s saddle when a man in polished mail stepped from the shadows of the stable doors. His surcoat bore the crest of the castle, and the last light of sunset flashed along the edge of his sword belt. “You must be Frederick,” the knight said, his voice steady and welcoming. “I am Sir Roland, master of the yard. We have been expecting you.” Frederick straightened at once, suddenly aware of the dust on his boots and the long road behind him. “Yes, sir,” he replied, trying to sound more confident than he felt. Sir Roland’s stern face softened with the hint of a smile as he glanced at the stallion. “A fine horse, and you sit him well. That is a good beginning. Come—your journey is done for tonight. The castle will test you soon enough.” With that, Sir Roland took the reins and led Frederick toward the lamplit stables, where the first chapter of the boy’s new life was about to begin. </nc-section> <nc-section data-title="Version 2" data-color="green"> The courtyard behind the castle was alive with the sounds of stamping hooves, clinking tack, and grooms calling to one another. Frederick had just reached the stables when a broad-shouldered knight emerged from within, carrying a lantern that painted gold across his weathered face. “So,” the knight said, studying him with sharp gray eyes, “you are the new squire.” Frederick nodded quickly. “Frederick, sir.” “Sir Roland,” the man answered. He set the lantern upon a post and looked the boy over from head to heel, measuring him as if he were already on a training field. “You made good time. Not every lad arrives before full dark.” Frederick swallowed, unsure whether he had earned praise or warning. Sir Roland rested a gloved hand on the horse’s neck, calming the stallion at once. “The stables first, then food, then sleep. Tomorrow, you will see whether castle life suits you.” His mouth twitched, almost amused. “And whether you suit it.” Frederick followed him inside, heart pounding with equal parts dread and excitement. </nc-section> <nc-section data-title="Version 3" data-color="blue"> As Frederick approached the stables, a tall knight was waiting beside the open doors, outlined by the warm light within. He wore a dark cloak over his armor, and his bearing was so calm and certain that Frederick knew at once this must be a man of rank. The knight inclined his head. “Welcome to Castle Alderwyn. I am Sir Roland.” Frederick quickly dismounted and bowed, nearly stumbling in his haste. “Forgive me, sir. I am Frederick. I have come to begin my training.” “Then you have come to the right place,” Sir Roland said. His voice was deep but not unkind. He stepped forward and laid a practiced hand on the bridle, easing the nervous horse. “Every good knight begins as you do now—cold, tired, and uncertain.” Frederick looked up, surprised. Sir Roland gave him a faint, knowing smile. “Do not fear that. Uncertainty can be sharpened into strength.” He nodded toward the stable interior, where rows of horses shifted in their stalls. “See your mount settled, then come with me. The castle has much to show you, and little patience for delay.” With those words, Frederick led his horse inside, feeling that the world he had dreamed of was finally opening before him. </nc-section>
