<nc-section data-title="Chapter 1: The Arrival - A Knight's Welcome" data-color="red"> As Thunder's hooves clattered to a stop on the cobblestones near the stables, a broad-shouldered man stepped out from the shadows of the doorway. His armor bore the deep crimson insignia of the royal guard, and a long scar traced down one side of his weathered face. "You must be the new squire," he said, his voice gruff but not unkind. "I am Sir Roland. I've been expecting you, though I confess I thought you'd arrive with less flair." He nodded toward Thunder, who was still catching his breath, nostrils flaring. "Come, let's get that horse settled before the stable boys retire for the night. We've much to discuss, young Frederick." </nc-section> <nc-section data-title="Chapter 1: The Arrival - A Knight's Welcome" data-color="green"> The stable doors creaked open before I'd even dismounted, and a tall figure emerged, wiping his hands on a cloth stained with saddle oil. His eyes were kind despite the weariness etched into his face, and a silver pendant bearing the kingdom's crest hung at his throat. "Frederick, is it?" he asked, extending a calloused hand to help me down. "I'm Sir Roland. Word travels fast in these halls—the whole castle's been abuzz about the new squire from the eastern villages." He smiled warmly as Thunder nuzzled his shoulder, clearly already fond of the stranger. "Don't worry, lad. I was just as nervous my first night here. Let's get you and your horse settled, shall we?" </nc-section> <nc-section data-title="Chapter 1: The Arrival - A Knight's Welcome" data-color="blue"> A lantern's glow spilled from the stable entrance as I approached, illuminating the figure of a knight leaning casually against the wooden frame. His polished breastplate caught the last rays of sunset, and his stance radiated the quiet confidence of someone who had seen countless battles. "Ah, so you're the boy who's been sent to train under Master Aldric," he said, pushing off from the doorway and walking toward me with measured steps. "Sir Roland, at your service. I oversee the younger squires' progress here." He studied me for a moment, his gaze sharp yet not unfriendly. "You've got a good horse there. Let's see if you handle a blade half as well as you handle him. Welcome to the castle, Frederick." </nc-section>
