<nc-section data-title="The Meeting with Sir Roland" data-color="red"> As I urged Thunder to a slow trot near the stables, a tall figure clad in gleaming armor stepped forward. Sir Roland, the local knight renowned for his valor, extended a strong hand in greeting. "Welcome to the castle, young squire," he said with a knowing smile. "Your journey has just begun." </nc-section> <nc-section data-title="A Knight's Welcome" data-color="green"> Near the stables, the sound of clinking armor announced the arrival of Sir Roland. Towering and resolute, he approached with a nod of respect. "Frederick, I've heard tales of your determination. Come, let us prepare you for the trials ahead," he said, leading the way towards the castle’s training yard. </nc-section> <nc-section data-title="Sir Roland's Greeting" data-color="blue"> I reined Thunder to a halt as Sir Roland appeared from the shadows of the stables. His piercing eyes met mine with a mixture of challenge and encouragement. "So, you’re the one who’ll carry the kingdom’s hopes," he said gravely. "We have much to teach you, and little time."
