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 reined Thunder to a halt beside the stables, the stallion's hooves clattering over the cobblestones. He had barely swung down from the saddle when a broad-shouldered man in a polished hauberk stepped out from the shadow of the barn doors. "So, you must be Frederick," the knight said, smiling beneath his close-cropped beard. He extended a strong, calloused hand. "I am Sir Roland. Lord Alden wrote that you were eager, punctual, and knew how to ride. It seems he was right on all three counts." Frederick's heart pounded as he shook the hand. "It is an honor, sir. I have come to begin my training, and I will not disappoint you." Sir Roland clapped him warmly on the shoulder and took Thunder's reins. "Come, then. Let us see to your horse first — a knight cares for his mount before himself. Afterward, I shall show you the castle where you will live, and the yard where you will learn to earn your spurs." </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable yard smelled of hay, leather, and horse sweat as Frederick dismounted. Thunder was still snorting from the gallop when a tall figure emerged between the stalls, arms folded across a scarred breastplate. "You ride fast, boy," the man said. His voice was flat, unimpressed. "The question is whether you ride well." Frederick straightened and bowed. "Frederick, sir. I have come—" "I know who you are." The knight's grey eyes flicked from Frederick to his horse. "I am Sir Roland, and while you are here, your training is mine to command. You are late by the sun, your saddle is crooked, and Thunder is lathered because you pushed him for the last mile to make an entrance." Heat rose to Frederick's cheeks, but Sir Roland tossed him a currycomb before he could speak. "Unsaddle him. Groom him. Water him — slowly. When that is done, muck his stall." Sir Roland turned to leave, then paused. "If you can serve a horse without complaint, Frederick, perhaps we can begin to make a squire of you." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Frederick led Thunder into the cool dimness of the stables, grateful for the shade after the long ride. He was reaching for a brush when a hand caught his wrist — firm, sudden, and silent as a shadow. The man who held him wore the crest of the kingdom, but his cloak was travel-stained and his sword was already half an inch from its sheath. He glanced toward the open doors before he spoke, low and urgent. "You are Frederick, are you not?" "Y-yes, sir," Frederick stammered. "And you—" "Sir Roland." The knight released him, but did not step back. "Listen well, and do not repeat what I am about to say in the great hall. You did not come here merely to train, boy, however fine that story sounds." Beyond the castle walls, something vast moved across the setting sun — too large for a bird, too silent for thunder. Sir Roland saw it too, and his jaw tightened. "The last dragon has awakened. And for reasons your father never told you, it has begun to hunt for you." </nc-section>
