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, Frederick reined in Thunder beneath the crimson shadow of the castle wall. A broad-shouldered knight stepped from the stalls, his silver armor dulled by years of use. “Frederick?” he called. “Yes, sir.” “I am Sir Roland, keeper of this garrison and, for the moment, your instructor.” His gaze traveled from the young squire to the magnificent stallion. “Your mount has spirit. See that you have more.” Before Frederick could answer, a deep rumble rolled across the evening sky. The horses stamped and shied. Sir Roland’s hand went to his sword. “Inside,” he ordered. “The dragon’s star has risen.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick found Sir Roland beside the stable doors, brushing mud from a warhorse’s flank. The local knight wore no helm, and a pale scar crossed his brow like a second, crooked smile. “You must be the new squire,” Roland said. “Frederick, isn’t it?” Frederick dismounted and bowed. “At your service, Sir Roland.” “Then your service begins with learning where everything belongs.” Roland pointed toward the stalls, the tack room, and a crooked pile of firewood. “A knight may face giants, but he cannot face them with a hungry horse or a broken saddle.” As Frederick set down his pack, he noticed a black feather lying in the straw. It was longer than his arm and warm to the touch. Sir Roland saw it—and abruptly closed the stable doors. </nc-section> <nc-section data-title="Version 3" data-color="blue"> The last light had turned the stable windows blue when Sir Roland emerged to meet Frederick. He was a lean knight in a weather-stained cloak, carrying a lantern whose flame burned without flickering. “Frederick,” he said quietly. “You arrived later than expected.” “I rode as swiftly as I could.” “I know.” Sir Roland glanced toward the road. “Something rode behind you.” Thunder whinnied and struck the ground with one hoof. Beyond the gates, the dusk lay empty, yet Frederick heard the faint scrape of claws upon stone. Roland lifted the lantern. Its flame flashed silver. “Stay close to me,” he whispered. “Your training can wait. Tonight, we discover whether the old stories are waking.” </nc-section>
