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: Sir Roland’s Welcome" data-color="red"> Thunder slowed to a proud trot as Frederick passed beneath the castle gate. Beyond the inner yard, the stables stood warm and golden in the fading light, their doors open wide against the evening chill. Horses stamped in their stalls, and the air smelled of hay, leather, and woodsmoke. A broad-shouldered knight waited beside the watering trough. He wore no helmet, and silver threaded the dark hair at his temples. Though his mail was plain and scarred from use, the sword at his hip bore the crest of the kingdom: a crowned dragon. “Frederick?” the man called. Frederick drew Thunder to a halt and slid from the saddle. “Yes, sir.” The knight’s stern expression softened into a faint smile. “Then I am Sir Roland, master of this garrison—and, for your sins, the knight charged with seeing whether you become useful.” Thunder tossed his mane, as if offended on Frederick’s behalf. Sir Roland gave the stallion an approving glance. “A fine horse,” he said. “But a castle has no need of fine horses alone. It needs riders who do not flee when the dark begins to stir.” Frederick’s hand tightened around Thunder’s reins. “What dark, sir?” Sir Roland looked toward the distant hills, where the last red light was dying. “You will hear enough of that before morning,” he said. “For now, see to your horse. Training begins at dawn.” </nc-section> <nc-section data-title="Version 2: The Knight by the Stables" data-color="green"> By the time Frederick reached the stables, Thunder’s flanks were damp with sweat and dust clung to the hem of Frederick’s cloak. Stablehands hurried through the courtyard carrying lanterns, their flames bobbing like fireflies in the dusk. One man did not hurry. He stood in the stable doorway with his arms folded across a weathered breastplate. A long scar ran from the corner of his mouth to his jaw, giving him the appearance of someone forever on the verge of a grim smile. His cloak was green, clasped at the throat with a bronze dragon pin. “Easy there,” he said as Thunder snorted. His voice was low but firm. “He knows a soldier when he sees one.” Frederick swallowed and bowed awkwardly. “Sir Roland?” “The same.” The knight stepped forward and took Thunder’s bridle with practiced gentleness. “And you must be the new squire from Briar Hollow.” “Yes, my lord.” “Do not call me that unless you want extra laps around the yard.” Sir Roland’s eyes gleamed with dry amusement. “Sir Roland will do.” A stablehand led Thunder away, but the stallion glanced back at Frederick, reluctant to leave him. Sir Roland watched the exchange closely. “Loyal,” he murmured. “That may save your life one day. Or cost you it.” Frederick frowned. “I don’t understand.” “No,” Sir Roland said, turning toward the darkened castle. “Not yet. Come. There is stew in the hall, and afterward you may tell me why a boy with no noble name has come to train beneath a banner marked by dragons.” </nc-section> <nc-section data-title="Version 3: A Warning at Dusk" data-color="blue"> The stable yard lay behind the castle’s main keep, sheltered from the wind by high stone walls. Frederick guided Thunder toward an empty hitching post, grateful at last to be off the road. Before he could dismount, a voice rose from the shadows beneath the eaves. “Keep your weight back when you stop him. A warhorse should be asked, not dragged.” Frederick stiffened. A knight emerged into the lantern light. Sir Roland was taller than Frederick had imagined, clad in a blue surcoat over battered armor. Rain had darkened the leather of his gloves, though no rain had fallen in the valley. His face was calm, but his pale eyes were fixed on the western horizon. Frederick quickly corrected his grip on the reins. Thunder settled at once. “There,” the knight said. “He trusts you.” Frederick climbed down from the saddle and bowed. “I am Frederick, sir. I was told to report to the castle for training.” “I know who you are.” Sir Roland’s gaze moved to the small travel pack at Frederick’s side. “Your arrival was expected three days ago.” “The river flooded, sir. We had to ride north around the old forest.” At this, Sir Roland’s expression changed. “You rode near the old forest?” “Yes.” “Did you see anything?” Frederick hesitated. For a moment he remembered the strange shape he had glimpsed through the trees—a vast shadow passing over the moonlit branches—and the distant sound that had not been thunder. “I heard something,” he admitted. Sir Roland’s hand closed around the pommel of his sword. “Then you may have arrived at exactly the wrong time,” the knight said softly. “Or exactly the right one.” </nc-section>
