<nc-section data-title="Arrival at the Stables" data-color="red"> Just as Thunder slowed to a trot before the cool stone of the stables, a broad-shouldered figure in polished steel plate stepped from the shadows. His helm was tucked under one arm, revealing a stern, weathered face and a thick grey beard. "Hold there, boy!" the knight commanded, his voice a gravelly boom. "You ride hard for the castle gates. I am Sir Roland. State your purpose." </nc-section> <nc-section data-title="The Stable's Welcome" data-color="green"> A gentle hand on Thunder's reins brought the horse to a halt. Looking up, Frederick saw a knight with kind eyes and a silver-streaked beard, his armor free of the day's grime. "Easy now, lad. He's a fine steed, but you've ridden him close to the bone." The knight smiled. "I am Sir Roland. You must be the new squire. Come, let's get him settled." </nc-section> <nc-section data-title="A Knight's Greeting" data-color="blue"> The grandeur of the stables was interrupted by the arrival of a knight in ceremonial tabard, his bearing as formal as the stone carvings above. He did not smile, but gave a slow, deliberate nod of acknowledgment. "Squire," he stated, his tone even. "I am Sir Roland, master of this hold. Your journey is complete. Your duties begin at dawn." </nc-section>
