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: The Knight at the Stable Yard" data-color="red"> Thunder’s hooves struck sparks from the cobbles as Frederick guided him beneath the shadow of the castle’s eastern wall. The stables lay ahead: a long, low building of dark timber and slate, warm lanternlight spilling from its open doors. The air smelled of hay, leather, and horses. A man waited beside the mounting block, broad-shouldered beneath a weathered blue cloak. His mail shirt gleamed faintly at his throat, and a sword rested at his hip—not ceremonially polished, Frederick noticed, but nicked and well-used. “You ride as though the road has been chasing you,” the knight said. Frederick swung down from Thunder’s saddle, suddenly aware of the dust on his boots and the travel stains on his tunic. “Perhaps it was, sir.” The knight’s stern face softened into a brief smile. “A sensible answer. I am Sir Roland, knight of these lands and master of the castle’s training yard.” Frederick bowed quickly. “Frederick of Alderfen, sir. I have come to serve as squire.” Sir Roland looked from the boy to Thunder, whose ears had pricked toward the stable. “Then you have come at an interesting hour. Put your horse in a stall, Frederick of Alderfen. At dawn, we shall see whether you can serve a knight as well as you can speak to one.” </nc-section> <nc-section data-title="Version 2: A Measure of Steel" data-color="green"> The castle gates groaned shut behind Frederick, muting the sound of the wind beyond the walls. He followed a torchlit path toward the stables, where grooms hurried between stalls with buckets and armfuls of straw. Before Frederick could dismount, a knight stepped from the stable doorway. He was tall and silver-haired, though no frailty showed in the way he moved. A scar ran from his left brow to the corner of his jaw, pale against sun-browned skin. He wore no helmet, only a simple leather jerkin over chain mail, and his gray eyes studied Frederick with unsettling calm. “Name yourself,” he said. Frederick swallowed. “Frederick, sir. I was sent from Alderfen to begin my service.” “And the name of the horse?” “Thunder.” At this, the knight glanced at the stallion, who tossed his black mane and stamped once upon the stones. “A bold name. Does he deserve it?” Frederick placed a steadying hand on Thunder’s neck. “Most days, sir.” The knight gave a low chuckle. “Good. A squire must know the difference between pride and truth.” He offered Frederick his forearm in greeting. “Sir Roland. This castle has need of strong hands, clear eyes, and honest answers. We shall discover which of those you possess.” Frederick clasped the knight’s arm, feeling the strength beneath the worn leather bracer. Somewhere deeper within the stable, a horse whinnied sharply. Sir Roland’s expression changed for only an instant—something like concern passing over it. “See to Thunder,” the knight said. “Then come to the hall. There are matters you should hear before you sleep.” </nc-section> <nc-section data-title="Version 3: The Dragon Mark" data-color="blue"> Frederick rode into the stable yard just as the last rim of sun vanished behind the western hills. Shadows gathered beneath the eaves, and Thunder snorted uneasily, his breath silver in the cooling air. A knight stood beside a lantern post near the stable doors. He wore a crimson surcoat over his armor, embroidered with the golden tower of the kingdom. Yet it was the clasp at his shoulder that caught Frederick’s eye: an old bronze brooch shaped like a dragon with its wings folded tight around a dark red stone. “Easy,” the knight murmured, though it was not clear whether he spoke to Thunder or Frederick. The stallion quieted at once. Frederick dismounted, staring at the dragon brooch. “Sir… is that a dragon?” The knight followed his gaze. For a heartbeat, his hand closed over the clasp. “It is an old symbol,” he said. “Older than this castle, perhaps older than the kingdom.” Then he turned, and Frederick saw the familiar authority in his weathered features. “I am Sir Roland. You must be the new squire from Alderfen.” “Yes, sir. Frederick.” “Welcome, Frederick.” Sir Roland’s voice was kind, but his eyes remained fixed on the darkening sky beyond the stable yard. “You arrived safely, and that is fortunate. Travelers have reported strange lights on the northern road.” Thunder stamped again. From far beyond the walls came a sound so distant Frederick could not be certain he had heard it: a long, low cry rolling over the hills like thunder. Sir Roland’s fingers tightened around the dragon clasp. “Take care of your horse,” he said quietly. “Tonight, keep your ears open.” </nc-section>
