<nc-section data-title="The Arrival: A Stern Welcome" data-color="red"> As I dismounted, the heavy thud of metal boots echoed against the cobblestones. Sir Roland emerged from the shadows of the stable, his face a map of jagged scars. He didn't offer a smile, only a narrowed glare that seemed to weigh my worth as a warrior. "You're late, boy," he growled, his hand resting ominous and heavy on the hilt of his broadsword. The air between us crackled with a sudden, suffocating tension. </nc-section> <nc-section data-title="The Arrival: A Lesson in Duty" data-color="green"> Sir Roland stood by the stable doors, brushes in hand, already hard at work grooming a massive warhorse. He looked up, his expression one of calm, weathered wisdom, and tossed a leather lead toward me. "The pride of a knight isn't in his title, squire, but in the care he gives to those who carry him into the fray," he said, his voice steady as iron. He gestured to the stalls, signaling that my true education was about to begin with the grime of the earth rather than the shine of a blade. </nc-section> <nc-section data-title="The Arrival: The Call to Arms" data-color="blue"> The knight approached with a measured, rhythmic stride, his cloak draped over one shoulder like a herald of destiny. Sir Roland stopped just inches from me, his eyes flickering with a strange, frantic energy as he peered toward the distant, smoke-stained mountains. "You arrive at a dark hour, Frederick," he murmured, his voice barely audible over the restless shuffling of the horses. "The dragons are waking, and the castle walls will soon be more than just stone—they will be our final line of defense." </nc-section>
