<nc-section data-title="Chapter 1: The Arrival" data-color="red"> As I dismounted near the stables, a tall, imposing figure in polished plate armor approached. "Welcome, Frederick," he boomed, his voice resonating with authority. "I am Sir Roland, Knight of the Green Valley. I trust your journey was uneventful." He extended a gauntleted hand, his grip firm and reassuring. </nc-section> <nc-section data-title="Chapter 1: The Arrival" data-color="green"> I led Thunder into the bustling stable yard, the scent of hay and horses filling the air. A man with kind eyes and a weathered face, dressed in a simple tunic but with a knight's insignia on his belt, stepped forward. "Frederick, I presume?" he asked, a gentle smile on his face. "I am Sir Roland. We've been expecting you." He offered a hand to help me with my saddlebags. </nc-section> <nc-section data-title="Chapter 1: The Arrival" data-color="blue"> After securing Thunder in a stall, I turned to survey my new surroundings. A voice, deep and resonant, startled me. "Lost, young squire?" I turned to see a formidable knight, Sir Roland, leaning against a stable post, his arms crossed. His eyes, though assessing, held a flicker of amusement. "Come, let's get you settled." He gestured towards the main keep. </nc-section>
