<nc-section data-title="Version 1: A Warrior's Welcome" data-color="red">
As I dismounted near the stables, a broad-shouldered figure strode toward me. His armor bore the scars of countless battles, and a weathered sword hung at his hip. "You must be Frederick," he said, his voice deep and commanding. "I am Sir Roland." He clasped my forearm in a grip that could crush stone. "I've heard much about you, young squire. Let us see if the stories hold true. Tomorrow at dawn, we test your mettle on the training grounds."

<nc-section data-title="Version 2: An Unexpected Kindness" data-color="green">
A tall knight emerged from the stables, wiping his hands on a cloth. His face, though lined with age, carried a gentle warmth that surprised me. "Ah, you've arrived at last," he said with a smile. "I am Sir Roland, and I'll be guiding your training." He helped me settle Thunder into a stall, his movements careful and practiced. "A fine animal. You've cared for him well. That tells me much about your character, Frederick. Come, you must be hungry after your long journey."
</nc-section>

<nc-section data-title="Version 3: A Test of Wits" data-color="blue">
"You're late," said a voice from the shadows of the stable. A lean knight stepped into the fading light, arms crossed, studying me with sharp, calculating eyes. "I am Sir Roland. Tell me, squire—did you take the eastern road or the western pass?" I hesitated, sensing this was no idle question. "The eastern road, my lord." He raised an eyebrow. "And what did you observe along the way?" I realized then that my training had already begun, and every word would be measured.
