My horse, a majestic stallion named Thunder, galloped across the open field. The wind whipped through my hair as I rode towards the castle gates. The sun was setting, casting a warm glow over the stone walls. I could see the banners of the kingdom fluttering in the breeze.

<nc-section data-title="Version 1" data-color="red"> Near the stables, the air was thick with the scent of hay, leather, and the lingering warmth of horses after a long ride. Frederick swung down from Thunder’s back, his boots striking the packed earth with more confidence than he felt. Before he could gather the reins properly, a broad-shouldered knight stepped from the shadow of the stable doors, his polished spurs catching the last light of evening. “Easy there,” the man said, his voice deep but not unkind. He reached for Thunder’s bridle with the ease of one long familiar with restless animals. “A fine horse, and a hard ride by the look of him.” Frederick straightened at once. “Yes, sir.” The knight studied him for a moment beneath heavy brows, then gave a small nod. “You’ll be Frederick, the new squire.” He rested a gauntleted hand against his chest. “I am Sir Roland, master of arms in these yards when the captain is away, and the man charged with seeing whether you’re worth the bed and bread the castle gives you.” Frederick felt his face warm, though whether from embarrassment or determination he could not tell. “I mean to be worth both, sir.” At that, Sir Roland’s stern expression softened into the faintest ghost of a smile. “Good. Words are light things, but I prefer a boy who speaks plainly.” He glanced toward the stable interior, where lanternlight flickered over stalls and harness racks. “Come along, then. Your horse will be rubbed down, and you’ll learn quickly enough that in this castle, we tend our beasts before we tend ourselves.” Frederick took the reins forward, following Sir Roland into the stable gloom, where the first true measure of his new life seemed about to begin. </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable yard rang with the sounds of evening—horses stamping in their stalls, grooms calling to one another, and the soft clatter of buckets against stone. Frederick had barely slid from the saddle when a knight in a weather-worn surcoat approached from beside the water trough. He moved with the steady confidence of a man who had spent half his life in armor and the other half commanding those who wore it. “So,” the knight said, folding his arms across his chest, “the boy from the outer farms has finally reached us.” Frederick swallowed and bowed his head. “Frederick, sir.” The man nodded once. His hair was touched with iron-gray at the temples, and a pale scar ran from his jaw to the edge of his collar. “Sir Roland,” he said. “You’ll answer to me in the training yard, and likely in the stables too, if I find you lazy.” Though his words were hard, there was a sharp intelligence in his gaze rather than cruelty. “I’m not lazy, sir,” Frederick said before he could stop himself. For a heartbeat, silence hung between them. Then Sir Roland let out a low chuckle. “Bold enough to speak honestly. That may serve you well—if you learn when to hold your tongue.” He stepped nearer and laid a hand against Thunder’s neck, calming the stallion at once. “You rode far. Did you care for this beast yourself on the road?” “Yes, sir. Fed him first every night.” “Good.” Sir Roland gestured toward the stable doors. “Then you’ve at least been taught one lesson properly. Bring him in. After that, you’ll eat, and tomorrow at dawn I’ll see whether your arms are as willing as your mouth.” Frederick nodded, his nerves twisting and tightening, yet beneath them something brighter stirred. Fear, yes—but also hope. He led Thunder forward, and Sir Roland walked beside him into the firelit heart of the stables. </nc-section> <nc-section data-title="Version 3" data-color="blue"> Frederick reined Thunder in beside the stables, where golden light spilled from open doors and turned the drifting dust to sparks. The long journey had left his limbs stiff and his thoughts uncertain, but he had scarcely set one foot to the ground before a knight emerged from within. He was not dressed for ceremony. His mail was half-covered by a plain dark cloak, and his hands bore the marks of work rather than idleness. Yet there was no mistaking what he was. He carried authority as naturally as another man carried a sword. “You’ve chosen a lively mount for your arrival,” he said, watching Thunder toss his head. Frederick tried to stand a little straighter. “He carried me well, sir.” “That he did.” The knight’s gaze shifted to Frederick, measuring him carefully. “And you are Frederick.” “Yes, sir.” “I am Sir Roland.” He inclined his head, neither cold nor warm, but grave. “I was told to expect a new squire before nightfall. I had begun to wonder whether the road had swallowed you.” Frederick gave a nervous smile, unsure whether the knight was jesting. “No, sir. Only delayed.” Sir Roland stepped forward and took the reins, his manner practiced and calm. Thunder, who tolerated strangers poorly, quieted almost at once. “A castle is a place of rules,” the knight said. “You will learn them soon enough. But the first is simple: any boy who wishes to serve here must respect steel, duty, and the creatures that bear men into battle. If you understand that, we may make something of you.” Frederick looked up at the looming walls, then back at the knight before him. “I understand, sir. Or I mean to.” Sir Roland regarded him a moment longer, then nodded toward the stable entrance. “That is a better answer than most. Come. There is water for the horse, supper for you, and dawn comes early in this castle.” With that, Frederick followed him inside, into the smell of straw and the glow of lanterns, where the first lessons of knighthood were waiting. </nc-section>
