<nc-section data-title="Version 1" data-color="red"> As Frederick dismounted near the ancient stables, the sound of heavy boots crunching on gravel echoed behind him. Sir Roland, the local knight whose reputation for stern discipline preceded him like a shadow, emerged from the shadows of the stable archway. His armor gleamed dully in the fading light, and his weathered face broke into a rare, approving smile. "Young Frederick, I see you've arrived without losing your way—or your nerve," Sir Roland said, his voice gruff yet welcoming as he clasped the squire's shoulder firmly. "The stables will be your first domain. Tend to Thunder, then we'll speak of what it truly means to serve under the Last Dragon's banner." </nc-section> <nc-section data-title="Version 2" data-color="green"> Thunder slowed to a trot as they approached the castle stables, the scent of hay and leather filling the air. Before Frederick could fully dismount, a towering figure stepped forward from the gloom between the stalls—Sir Roland, the grizzled local knight known for his unyielding sense of honor. His eyes, sharp as a falcon's, scanned the young squire from head to toe. "Hail, Frederick," Sir Roland greeted, his tone laced with the weight of years spent in service. He took the reins with calloused hands, nodding approvingly at the stallion. "You've a fine mount and a steadier hand than most lads your age. Come, lad—before the shadows lengthen further, let us discuss your training. The castle holds secrets that only the worthy may learn." </nc-section> <nc-section data-title="Version 3" data-color="blue"> The stable yard was alive with the soft nickers of horses as Frederick guided Thunder to a hitching post, his heart pounding with a mix of excitement and trepidation. From the wide doors of the barn strode Sir Roland, the local knight whose legendary deeds against dark forces were whispered in every tavern. Clad in a simple tunic beneath his half-plate, Roland's presence commanded respect without a word. He extended a gauntleted hand in greeting, his voice warm yet firm like tempered steel. "Frederick, the squire from the hills—I've been expecting you. Welcome to Eldridge Castle. Tend to your steed swiftly, for the path of the dragon's guardian begins tonight. What tales have you heard of the Last Dragon that brings you here?" </nc-section>
