<nc-section data-title="Chapter 2: The Knight's Welcome" data-color="red">
As I dismounted near the stables, a broad-shouldered figure clad in worn chainmail strode toward me. His weathered face bore the scars of countless battles, yet his eyes were kind beneath his graying brow.

"You must be Frederick," he said, his voice deep and commanding. "I am Sir Roland, knight of this realm. I have heard much about you from your father." He clasped my forearm in a firm grip. "The road has been long, I imagine. Tend to your horse, and then we shall speak of the duties that await you."

I felt a swell of pride and nervousness. This was the man who would shape me into a knight.

<nc-section data-title="Chapter 2: An Unexpected Meeting" data-color="green">
The stable doors creaked open, and out stepped a tall man brushing straw from his tunic. Unlike the polished knights I had imagined, Sir Roland looked more like a farmer than a warrior—until I noticed the longsword at his hip and the steady, assessing gaze he fixed upon me.

"So, the new squire arrives at last," he chuckled, wiping his hands. "I'm Roland. No need for all the 'Sir' nonsense when it's just the two of us and the horses." He nodded toward Thunder. "Fine beast you've got there. A knight is only as good as how he treats his mount. Remember that, lad."

There was something disarming about him, and I found myself smiling despite my exhaustion.

<nc-section data-title="Chapter 2: First Impressions" data-color="blue">
A shadow fell across the stable entrance as I led Thunder inside. Sir Roland waited there, arms crossed, his armor gleaming faintly in the dying light. He said nothing at first, only studied me with an intensity that made my heart quicken.

"They told me you were young," he finally murmured, circling me slowly like a hawk surveying its prey. "But youth is no excuse for weakness. Training here is harder than anything you've known, Frederick. Many squires break before they earn their spurs." He paused, and the faintest hint of a smile touched his lips. "But something tells me you might be different. We shall see at dawn."

With that, he turned and vanished into the deepening twilight, leaving me to wonder what trials lay ahead.
