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"> Near the stables, a broad-shouldered knight waited beneath a weathered archway. His silver armor caught the last light of sunset, and a faded crimson cloak hung from one shoulder. “You must be Frederick,” he said as Thunder slowed to a halt. “I am Sir Roland. Welcome to the castle.” Frederick dismounted and bowed, trying not to show how sore the long journey had left him. Sir Roland inspected him with a stern, measuring gaze. Then the corner of his mouth lifted. “See to your horse. At dawn, we discover whether you belong in a saddle—or beneath one.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick had scarcely reached the stables when a tall knight emerged from between the stalls, carrying a bucket in one hand and a polished helm beneath the other arm. “Easy there,” the knight said, catching Thunder’s bridle before the restless stallion could snap at a stable boy. “A proud horse needs a patient rider.” Frederick flushed. “Are you the stablemaster?” The man laughed, deep and warm. “Sir Roland, at your service—and, until supper, apparently the stablemaster as well.” He offered Frederick a calloused hand. “Come. Help me brush him down, and you can tell me why a young squire has ridden half the kingdom to train within these walls.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> A lone figure stood near the stables as twilight gathered over the castle yard. The knight wore dark mail beneath a blue surcoat, and a long scar traced the line of his jaw. At his hip hung a sword whose pommel was shaped like a dragon’s claw. “Frederick,” he called before the young squire could introduce himself. Thunder shied beneath Frederick, nostrils flaring. From somewhere inside the stable came a low, unnatural growl. Sir Roland’s hand moved toward his sword. “You arrived sooner than I expected,” he said quietly. “That may be fortunate. Something crossed the northern wall last night, and whatever it was has taken an interest in the horses.” </nc-section>
