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: A Knight at Dusk" data-color="red"> Thunder slowed to a proud walk as Frederick entered the stable yard. Lanterns were being lit beneath the eaves, their gold light pooling over wet cobbles and piles of fresh straw. Before Frederick could dismount, a broad-shouldered knight stepped from the shadows beside the stable doors. He wore no helm, only a dark cloak clasped with silver, and a pale scar crossed one cheek like an old stroke of lightning. “Frederick?” the man asked. “Yes, sir.” “I am Sir Roland, knight of this keep and, for the present, the fellow charged with making certain you do not break your neck before your first lesson.” Despite the weariness in his bones, Frederick smiled. “I shall do my best not to disappoint you, Sir Roland.” Sir Roland’s stern face softened by the smallest degree. He took Thunder’s reins and looked the stallion over with an experienced eye. “A fine mount,” he said. “A good horse knows more of a rider’s heart than any master-at-arms. Stable him well. Then come to the great hall. Supper is waiting—and tomorrow, your real journey begins.” </nc-section> <nc-section data-title="Version 2: The Measure of a Squire" data-color="green"> The castle gates groaned shut behind Frederick, sealing out the fading light of the road. Thunder’s hooves rang against the stones as he guided the stallion toward the stables. The air smelled of hay, leather, and woodsmoke. A knight stood waiting beside the stable entrance, his armor burnished but plainly used. He had the square hands and weathered face of a man who had spent more years in the saddle than in a lord’s chamber. “You came alone?” he asked. Frederick slid from Thunder’s back and bowed. “Yes, sir. My father said a squire must learn to find his own road.” The knight studied him for a long moment. “Wise words. Though roads are kinder than some of the lessons you will find here.” He extended a gloved hand. “Sir Roland. This castle is my charge when its lord is away.” “Frederick, sir.” “I know.” Sir Roland glanced at the dust on Frederick’s cloak, then at the sword hanging awkwardly at his belt. “Bring your horse inside. You may be a squire now, boy, but a knight is first judged by how he treats a creature that cannot speak in his defense.” Frederick nodded gravely and led Thunder toward the warm glow of the stables. </nc-section> <nc-section data-title="Version 3: The Dragon Mark" data-color="blue"> Frederick had barely reached the stables when Thunder stopped short and tossed his head. A figure emerged from between the lantern-lit stalls: a knight in a deep blue surcoat, embroidered at the breast with the golden crest of a dragon. The man’s hand rested on the hilt of his sword, though his expression held more curiosity than threat. “Easy,” Frederick murmured, stroking Thunder’s neck. “Your horse has good instincts,” said the knight. His voice was low and steady. “The old stones make many creatures uneasy after dark.” Frederick looked past him toward the castle walls. For an instant, he thought he saw a long, black shape pass over the highest tower—but when he blinked, there was only smoke curling from the chimneys. “I am Sir Roland,” the knight said. “You must be Frederick, the new squire.” “Yes, sir.” Sir Roland’s gaze settled on the small pendant at Frederick’s throat, a simple piece of silver Frederick had worn since childhood. The knight’s face changed. Not with fear exactly, but recognition. “Keep that hidden beneath your tunic,” he said quietly. Frederick’s fingers closed around the pendant. “Why?” Sir Roland looked toward the darkening sky beyond the stable roof. “Because,” he replied, “there are old signs in this kingdom that some men would rather never see again.” </nc-section>
