<nc-section data-title="A Stern Welcome" data-color="red">
As I dismounted near the stables, a towering figure emerged from the shadows of the doorway. Sir Roland, his armor still bearing the dust of the training yard, fixed me with a hard, appraising stare. "So, you're the new squire," he grunted, crossing his arms over his broad chest. "Let me make one thing clear, boy. I have no patience for the soft sons of nobles who think this is a game. Here, you will bleed, you will sweat, and you will learn—or you will leave. Which will it be?"

<nc-section data-title="An Unexpected Kindness" data-color="green">
I had barely led Thunder toward the stables when a warm voice called out to me. "Welcome, lad! You must be Frederick." Sir Roland strode forward, a genuine smile breaking across his weathered face. Though his frame was that of a seasoned warrior, his eyes held a gentle wisdom. He clapped a heavy hand on my shoulder and helped me with the saddle. "Don't look so nervous. We were all young squires once. Come, let me show you where Thunder can rest. A knight always tends to his horse before himself—remember that."

<nc-section data-title="A Riddle in the Twilight" data-color="blue">
As the last light faded, I noticed a man leaning casually against the stable wall, half-hidden in shadow. He did not announce himself, but watched me with curious, glittering eyes. "Tell me, young one," Sir Roland said at last, his voice soft and measured, "do you know why the dragon banners no longer fly above these gates?" I shook my head, confused by such a strange greeting. He pushed off from the wall and stepped into the dying light, his expression unreadable. "No. Of course you don't. But you will. That, I'm afraid, is precisely why you were summoned here."
