<nc-section data-title="Version 1: Sir Roland's Greeting" data-color="red">
As I dismounted Thunder near the stables, a gruff voice cut through the evening air. "You must be the new squire." Sir Roland emerged from the shadows, his armor catching the last rays of sunlight. He was a broad-shouldered man with a scar running down his left cheek — a mark of countless battles. He looked me up and down with sharp, scrutinizing eyes. "You're smaller than I expected," he said flatly. "But size matters little. It's what burns in your chest that makes a knight." He thrust a bucket into my hands. "Now then — tend to your horse. We begin at dawn."

<nc-section data-title="Version 2: Sir Roland's Greeting" data-color="green">
The stables smelled of hay and leather as I led Thunder through the gates. A warm laugh startled me from behind. "Ah, Frederick! At last you arrive!" Sir Roland strode toward me with an outstretched hand and a wide, genuine smile beneath his silver beard. He was older than I had imagined, but his grip was iron-firm. "Your father was my dearest friend and the finest knight I ever knew," he said, placing a steady hand on my shoulder. "I intend to honor his memory by making you even greater. Welcome, boy. Welcome home."

<nc-section data-title="Version 3: Sir Roland's Greeting" data-color="blue">
I had barely tied Thunder's reins to the post when I sensed someone watching me. Sir Roland stood at the stable entrance, arms crossed, his expression unreadable beneath the torchlight. He said nothing for a long moment — only studied me as though searching for something hidden beneath my features. Finally, he spoke in a low, measured tone. "Do you know why you were truly sent here, boy?" I shook my head slowly. A strange glint passed through his eyes. "You will," he whispered. "When the dragon comes, you will understand everything." He turned and disappeared into the dark corridor, leaving me alone with the wind and the distant sound of wings.
