<nc-section data-title="Chapter 2: The Knight's Welcome" data-color="red">
As I dismounted near the stables, a broad-shouldered man in gleaming armor strode toward me. His weathered face bore the scars of countless battles, yet his eyes held a surprising warmth. "You must be Frederick," he said, his voice deep and commanding. "I am Sir Roland, and I have been expecting you." He clasped my forearm in a firm grip. "Your father spoke highly of you before he passed. I trust you will honor his memory in your training."

<nc-section data-title="Chapter 2: An Unexpected Greeting" data-color="green">
The stable doors creaked open before I could lead Thunder inside, and out stepped a tall figure clad in polished mail. "Ho there, young one!" he called, a grin splitting his bearded face. "I am Sir Roland, master-at-arms of this keep. You ride well for a boy your age." He patted Thunder's flank with an appraising nod. "A fine beast, too. Come, leave him to the grooms. There is much to discuss before the evening meal, and even more to learn before the morrow."
</nc-section>

<nc-section data-title="Chapter 2: The Shadow by the Stables" data-color="blue">
A shadow detached itself from the stable wall as I approached, resolving into the shape of a knight whose armor caught the dying light. He said nothing at first, only studying me with piercing grey eyes that seemed to measure my very soul. At last he spoke. "Frederick. They told me you would come." His tone was neither warm nor cold. "I am Sir Roland. Whether you prove worthy of these walls remains to be seen. Tend to your horse, then follow me. Your training begins tonight."
