<nc-section data-title="Version 1: Red" data-color="red"> As I approached the bustling stables, a tall figure clad in shining armor stepped forward. Sir Roland, the kingdom’s famed knight, eyed me with a stern yet welcoming gaze. "You must be Frederick," he said, voice firm. "Come, I’ll show you where you'll tend your steed and prepare for the days ahead. Be ready for the trials to come." The flames of the setting sun cast a reddish hue over his armor as he extended a gauntleted hand. </nc-section> <nc-section data-title="Version 2: Green" data-color="green"> Near the stables, a knight in emerald-tinted armor approached me with a calm and composed demeanor. Sir Roland’s kind eyes studied me kindly as he offered a reassuring smile. "Welcome, young squire," he said softly. "Your journey begins here. Let me help you settle your horse and prepare for what’s to come." The lush greenery around us seemed to embrace the moment, a gentle reminder of the harmony between man and nature. </nc-section> <nc-section data-title="Version 3: Blue" data-color="blue"> By the stables, Sir Roland, clad in azure armor that shimmered in the dying light, stepped forward with measured grace. His deep, steady voice greeted me. "Frederick, I've been expecting you," he said. "Come, let’s see to your steed and get you acquainted with the life of a knight-in-training." The cool blue tones of his armor reflected the evening sky, embodying calm and purpose as he gestured kindly for me to follow. </nc-section>
