<nc-section data-title="The Stern Welcome" data-color="red"> As I dismounted, the heavy thud of plate mail echoed against the cobblestones. Sir Roland emerged from the shadows of the stable, his face a roadmap of scars and sun-worn leather. He didn't offer a smile, only a sharp glare that pinned me in place. "The stables are for those who work, boy," he growled, tossing a pitchfork toward my feet. "If you intend to survive this keep, you’ll start by earning your keep in the dung." </nc-section> <nc-section data-title="A Mentor's Gaze" data-color="green"> The scent of hay and horses greeted me as I swung down from Thunder’s back. Sir Roland was already there, meticulously polishing his gauntlets with a rag. He looked up, his eyes a piercing, thoughtful grey. "You handle that beast with surprising gentleness, Frederick," he noted, his voice surprisingly calm. He stepped forward and placed a heavy, reassuring hand on my shoulder. "Gentleness is a virtue in a squire, but soon, you will learn that steel requires a colder heart." </nc-section> <nc-section data-title="The Rushed Introduction" data-color="blue"> "Late, squire!" Sir Roland bellowed, though a twinkle of amusement betrayed his mock irritation. He stood near the stable entrance, wiping grease from his fingers. "I had expected you by midday, but the road from the valley is treacherous, I suppose." He barked an order to a stable hand to see to my horse before turning back to me. "Unpack your things quickly. The twilight training drills are starting at the practice yard, and you have much to catch up on if you’re to be a dragon-rider." </nc-section>
