<nc-section data-title="Chapter 2: The Welcome" data-color="red">
As I dismounted near the stables, a tall figure emerged from the shadows. Sir Roland, clad in polished armor that gleamed in the fading light, strode toward me with purpose. His weathered face bore the marks 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. We have been expecting you." He extended a calloused hand, and when I clasped it, his grip was like iron. "Welcome to your new home, squire. Your training begins at dawn."

<nc-section data-title="Chapter 2: The Stablemaster's Knight" data-color="green">
The smell of hay and horses greeted me as I led Thunder toward the stables. A knight was already there, brushing down a magnificent white mare with gentle, practiced strokes. He looked up at my approach, and a broad smile spread across his bearded face.

"Ah, the new squire arrives at last!" Sir Roland exclaimed, setting down his brush. "I wondered when you'd make it. The roads can be treacherous this time of year." He patted his mare affectionately before walking over. "Come, let me help you settle Thunder here. A knight learns to care for his horse before himself—remember that, lad. It's the first lesson, and the most important."

<nc-section data-title="Chapter 2: A Stern Greeting" data-color="blue">
I had barely tied Thunder's reins to the post when a shadow fell across me. Sir Roland stood with arms crossed, his expression unreadable beneath the dim torchlight. He studied me for a long moment, measuring, judging.

"So you're the one they sent," he finally said, circling around me as one might inspect a horse before purchase. "You look young. Soft, even." He stopped before me, his steel-grey eyes piercing. "But I've made knights out of softer clay than you. The question is whether you have the will to be forged." He turned away. "Follow me. We'll see what you're made of soon enough."
