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="Sir Roland's Greeting (Red)" data-color="red"> As I dismounted, a gruff voice boomed, "You must be the new recruit. Frederick, isn't it?" A towering knight, his armor scarred and his beard grizzled, approached from the shadows of the stables. This must be Sir Roland, the famed dragon slayer. </nc-section> <nc-section data-title="Sir Roland's Greeting (Green)" data-color="green"> Thunder neighed softly as I patted his flank, the familiar scent of hay and horse sweat filling the air. A silhouette detached itself from the dim light of the stable entrance. "Welcome to Oakhaven, squire," a deep voice announced. A knight, broad-shouldered and clad in polished steel, stepped forward, his gaze sharp and assessing. "I am Sir Roland." </nc-section> <nc-section data-title="Sir Roland's Greeting (Blue)" data-color="blue"> I led Thunder into the stable yard, the clatter of his hooves echoing against the stone. A figure leaned against a post, arms crossed, his presence commanding. "Frederick, I presume?" The knight's voice was like gravel, rough but steady. He pushed himself off the post. "Sir Roland. You've finally arrived." </nc-section>
