<nc-section data-title="Chapter 1: The Arrival" data-color="red"> As I dismounted near the bustling stables, a figure emerged from the shadows of an archway. He was a tall, broad-shouldered man, his polished armor gleaming in the fading light. A lion's head was emblazoned on his shield, leaning casually against the stone wall beside him. "Welcome to Dragon's Breath, young squire," Sir Roland boomed, his voice resonating with an authority that belied his friendly smile. "I trust your journey was uneventful?" </nc-section> <nc-section data-title="Chapter 1: The Arrival" data-color="green"> The air around the stables was thick with the scent of hay and horseflesh. I was just leading Thunder into an empty stall when a gruff, yet not unkind, voice startled me. "That's a fine animal you've got there, lad." Turning, I saw a knight, his surcoat adorned with the crest of a silver falcon, observing me with keen blue eyes. "Sir Roland, at your service," he introduced himself, extending a gauntleted hand. "And you must be Frederick, our newest squire." </nc-section> <nc-section data-title="Chapter 1: The Arrival" data-color="blue"> I had barely secured Thunder's lead when a shadow fell over me. Looking up, I saw a knight of imposing stature, his gaze unwavering but not unfriendly. He wore a simple, functional armor, yet carried an air of quiet dignity. "Frederick, I presume?" he asked, his voice a low rumble. "I am Sir Roland. The stable master will see to your mount. Come, the Lady Elara awaits your introduction." He gestured towards the castle's main courtyard, his presence radiating a calm strength. </nc-section>
