<nc-section data-title="Version 1: The Stern Mentor" data-color="red"> Thunder snorted and pawed the cobblestones as I dismounted near the stables. A towering knight in battered plate armor stepped forward, his gauntlets gleaming in the torchlight. "You're Frederick, the new squire?" His voice was like grinding stone. "I am Sir Roland. You will learn discipline here—or you will learn the weight of my boot. See to your horse, then report to the armory." He turned without waiting for a reply, his cloak billowing. </nc-section> <nc-section data-title="Version 2: The Warm Welcome" data-color="green"> The stable master took Thunder's reins with a nod, and before I could brush the road dust from my tunic, a hand clapped my shoulder. I spun to find a knight with a friendly, weathered face and laughing eyes. "Young Frederick! I'm Sir Roland. Heard tales of your journey—you made fine time." He gestured toward the castle. "Come, I've saved you a seat at the evening feast. We'll talk of dragons and quests over a warm meal." </nc-section> <nc-section data-title="Version 3: The Silent Observer" data-color="blue"> As I led Thunder toward the stable's shadow, a figure leaned against the wooden post, arms crossed. He wore no helm, and his silver-streaked beard caught the fading light. "Sir Roland," he said simply, not a question. He studied me with quiet, gray eyes, then nodded once. "Your horse is well-traveled. The stable boy will tend him. Follow me." He turned and walked into the deepening dusk, expecting me to follow without a word. </nc-section>
