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"> Frederick slid from the saddle with stiff legs and a racing heart, the smell of hay and horseflesh rising warm from the nearby stables. Before he could take more than a few steps, a broad-shouldered knight emerged from the shadow of the stable doors. His mail caught the last light of evening, and the red cloak at his back stirred in the wind. “You’ll be Frederick,” the knight said, his voice deep but not unkind. “Sir Roland of Greywatch. I was told to expect a new squire before sundown.” Frederick straightened at once and bowed his head. “Yes, sir.” Sir Roland studied him for a moment, taking in the dust of the road on his boots and the uncertainty he could not quite hide. Then the knight’s stern expression softened into the faintest smile. “Well enough,” Roland said. “You made the journey, and that is more than some boys manage without complaint. Hand your reins here.” He took the horse with practiced ease, laying a steady palm against its neck. The animal, restless from travel, calmed at once. “You’ll learn quickly in this castle,” Sir Roland went on as he led Frederick toward the stable entrance. “How to ride, how to keep your blade, how to hold your tongue, and—if fortune favors you—how to survive the tempers of men more dangerous than steel.” Frederick swallowed and followed close behind. From within the stables came the low murmur of grooms and the stamping of hooves, but beneath it all he felt something else in Sir Roland’s words: a warning, quiet and grave, as though the castle held more than stone walls and noble banners. For the first time since arriving, Frederick understood that he had not merely come to serve. He had stepped into a place where every shadow might carry a secret. </nc-section> <nc-section data-title="Version 2" data-color="green"> The stableyard bustled with evening chores as Frederick approached, leading his horse by the reins. Lanterns had begun to glow beneath the eaves, and the air was rich with the scent of straw, leather, and rain-damp earth. A knight stood near the water trough, removing his gauntlets one finger at a time, as if in no great hurry at all. He turned when Frederick entered the yard. His face was weathered, his beard touched with iron gray, and a pale scar crossed one brow. “So,” he said, “the castle sends boys younger every year.” Frederick flushed, unsure whether he had been insulted. “I am Frederick, sir. Come to serve as squire.” The knight gave a short nod. “Sir Roland. I oversee the training yard when the master-at-arms is busy shouting himself hoarse elsewhere.” There was a dryness to his tone that caught Frederick off guard. Not mockery, exactly—something lighter, sharper. Roland stepped forward and took the horse’s bridle, his hands gentle despite their size. “You sit well enough for a long ride. That’s something. Have you any skill with sword or lance?” “A little, sir.” “A little usually means none,” Roland replied. Then, seeing Frederick’s anxious look, he added, “That can be remedied.” A stableboy hurried over to take the horse, and Roland gestured for Frederick to follow him beneath the stable arch. “Listen carefully. In this castle, pride is expensive, laziness is punished, and foolish courage gets a lad buried early. Ask questions. Watch everyone. Speak less than you think.” Frederick nodded. Roland looked toward the darkening towers above them, where the first stars were kindling over the battlements. “Do that,” he said quietly, “and you may yet become more than a boy carrying another man’s shield.” Something in Frederick stirred at those words—not comfort, exactly, but purpose. He drew a breath, squared his shoulders, and followed Sir Roland into the deepening twilight of the castle. </nc-section> <nc-section data-title="Version 3" data-color="blue"> By the time Frederick reached the stables, the sky above the castle had faded to a deep violet, and swallows wheeled in restless circles beneath the roofs. He had barely loosened his grip on the reins when a knight in polished half-plate stepped out from between the stalls. The man moved with an ease that spoke of long habit, every motion controlled, efficient, and calm. A silver wolf was worked into the clasp of his cloak, and his keen eyes settled on Frederick at once. “You are late by half an hour,” he said. Frederick’s stomach dropped. “Forgive me, sir. The north road was washed through near the river crossing.” The knight held his gaze for a moment, then gave a curt nod. “A better answer than most. Sir Roland.” Frederick bowed quickly. “Frederick, sir.” Roland reached for the reins. “The horse first. A careless boy blames his mount; a good one sees to it before himself.” Frederick surrendered the reins at once, and Roland’s approval showed only in the slightest lift of his brow. He examined the horse’s flanks, the worn leather of the tack, and the mud dried along Frederick’s boots. “You’ve ridden hard,” Roland said. “Good. It means you understand urgency, if not punctuality.” A few stablehands nearby smothered grins, and Frederick felt heat creep into his face. Yet Sir Roland’s next words were measured rather than cruel. “You need not fear me, lad. But you will learn discipline. This castle is not a place for dreamers who mistake songs for truth.” He handed the horse off to a groom, then turned back toward Frederick. Behind him, the stable lanterns threw bars of gold across the cobbles, while the high towers loomed like watchful giants above. “Come,” Roland said. “You’ll be shown your quarters, fed if the kitchens have not closed, and at dawn you’ll begin learning how little you know.” Frederick followed, nervous but determined. And as he crossed the stableyard at Sir Roland’s side, he sensed that the knight’s greeting was more than courtesy—it was the first test of many yet to come. </nc-section>
