<nc-section data-title="Version 1: The Knight's Welcome" data-color="red"> As Frederick reined in Thunder near the castle stables, the scent of hay and leather filled the air. A towering figure in polished armor strode forward, his cloak emblazoned with a golden dragon. "Hail, young squire!" boomed Sir Roland, his voice deep and commanding. "I am Sir Roland of the Dragon Guard. Welcome to our halls. Your training begins at dawn—tend to your horse, then report to the great hall." Frederick dismounted, heart pounding with excitement and nerves as the knight's firm handshake sealed his new path. </nc-section> <nc-section data-title="Version 2: Shadows of the Stables" data-color="green"> Thunder's hooves clattered to a halt by the dimly lit stables as twilight deepened. From the shadows stepped Sir Roland, a battle-scarred knight with eyes like steel. "So, you're Frederick," he said gruffly, appraising the boy with a nod. "The last dragon's bloodline ends with our vigilance. Unload your gear and stable your mount—I'll see to your induction myself. No soft welcomes here, lad." Frederick felt a chill of destiny as the knight clapped him on the shoulder, guiding him into the fortress's secrets. </nc-section> <nc-section data-title="Version 3: Bonds of Knighthood" data-color="blue"> Approaching the bustling stables under the fading sunset, Frederick spotted a knight brushing down a white charger. Sir Roland turned, smiling warmly beneath his silver helm. "Frederick, is it? I've heard tales of your determination," he greeted, offering a steadying hand as the squire slid from Thunder's back. "Come, friend. The stables hold more than horses—they cradle legends. Let me show you around, and we'll discuss your role in the Chronicles of the Last Dragon over supper." In that moment, Frederick sensed not just a trainer, but a mentor who would shape his fate. </nc-section>
