<nc-section data-title="Chapter 1: The Arrival - Version 1" data-color="red"> I pulled back on Thunder's reins, the stallion's hooves striking sparks against the cobblestones as we breached the main gates. The pungent smell of hay and damp earth signaled our arrival at the castle stables. Emerging from the shadows of the wooden awnings was a towering figure clad in battle-scarred mail. Sir Roland, the legendary local knight, stepped forward, resting a heavy gauntleted hand on his sword hilt. "Easy there, boy," the knight rumbled, his voice like grinding stones. "You ride like a dragon's on your tail. I am Sir Roland. Welcome to your new life, Frederick." </nc-section> <nc-section data-title="Chapter 1: The Arrival - Version 2" data-color="green"> As we trotted through the arched gateway, the frantic galloping gave way to the steady, rhythmic clopping of hooves on stone. I guided Thunder toward the warmth of the stables, where golden lantern light spilled out onto the hay-strewn courtyard. A broad-shouldered man was brushing a magnificent gray destrier nearby. He turned at our approach, revealing the warm, weathered face of Sir Roland. Setting his brush aside, the seasoned knight wiped his hands on a linen cloth and offered an encouraging smile. "A fine, spirited beast you have there, young squire," he said warmly. "I am Sir Roland. Let's get your horse watered, Frederick, and then we will begin." </nc-section> <nc-section data-title="Chapter 1: The Arrival - Version 3" data-color="blue"> The evening air grew crisp as I rode deeper into the castle grounds, slowing Thunder to a graceful walk. The vast stables lay at the edge of the lower courtyard, bathed in the twilight's deepening shadows. Standing perfectly still beneath the stone archway was Sir Roland, his silver-trimmed cloak billowing slightly in the evening chill. His eyes, sharp and calculating, studied me as I slid from the saddle. He didn't speak immediately, letting the solemn silence weigh between us before he gave a slow, respectful nod. "You have made good time, Frederick," the knight said softly, his tone carrying the quiet authority of a master swordsman. "Leave the stallion with the hostlers. Your training begins tonight." </nc-section>
