<nc-section data-title="A Stern Welcome" data-color="red">
As I dismounted near the stables, a broad-shouldered figure emerged from the shadows of the doorway. Sir Roland was a mountain of a man, his graying beard framing a face weathered by countless battles. His steel-gray eyes appraised me from head to toe, lingering on my soft hands and travel-worn boots.

"So, you're the new squire," he said, his voice like grinding stone. "I expected someone less... fragile." He crossed his arms over his broad chest. "We'll see if you've got iron in your spine or merely water in your veins. Training begins at dawn—and I do not tolerate latecomers."

<nc-section data-title="An Unexpected Kindness" data-color="green">
A warm voice called out as I led Thunder toward the stables. "You must be young Frederick!" Sir Roland approached with a genuine smile, his hand extended in greeting. Though his frame was powerful and his armor bore the scars of war, there was a gentleness in his manner that put me instantly at ease.

"Welcome, lad. I've heard good things from your father—he and I served together in the southern campaigns." He clapped a firm hand on my shoulder. "You've had a long journey. Let me help you settle Thunder here, and then we'll find you a hot meal. Training can wait until you've rested."
</nc-section>

<nc-section data-title="A Mysterious Encounter" data-color="blue">
The stables were quiet as I guided Thunder inside, the only sounds the soft nickering of horses and the rustle of hay. Then I noticed him—a knight standing motionless in the dim light, his back to me as he tended to a magnificent black destrier.

"You arrive at a strange time, squire," Sir Roland said without turning, his voice low and measured. When he finally faced me, I saw eyes that seemed to carry the weight of secrets untold. "Dark things stir in the kingdom, Frederick. Things the elders refuse to speak of." He stepped closer, lowering his voice. "Tell me—have you ever heard the legends of the last dragon?"
