<nc-section data-title="Version 1: Sir Roland's Greeting" data-color="red">
As I dismounted Thunder near the stables, a broad-shouldered knight strode towards me, his armor gleaming in the fading sunlight. Sir Roland was an imposing figure, his face weathered by years of battle, a scar running from his left eye to his jaw. He crossed his arms and looked me up and down with a stern, appraising gaze.

"So you're the new squire," he said, his voice deep and gravelly. "You're smaller than I expected." He reached out and grabbed my shoulder with an iron grip. "But size matters little if the heart is strong. Come, boy. There is much work to be done before nightfall."

<nc-section data-title="Version 2: Sir Roland's Greeting" data-color="green">
The stables smelled of hay and leather as I led Thunder inside. A knight appeared from one of the stalls, brushing straw from his silver-streaked beard and smiling warmly. Sir Roland had kind eyes, the sort that crinkled at the corners when he laughed, and he laughed often.

"Welcome, Frederick!" he boomed, clasping my hand in a firm shake. "I have heard great things about you from your father. Come, let us get your horse settled, and then I shall show you to your quarters. Tonight, we feast — your training begins in earnest tomorrow!"
</nc-section>

<nc-section data-title="Version 3: Sir Roland's Greeting" data-color="blue">
I had barely tied Thunder to the post outside the stables when a shadow fell over me. Sir Roland stood in the doorway, silent as a ghost, watching me with pale, unreadable eyes. He was not as large as I had imagined a knight to be, but there was something about the way he carried himself — still and coiled, like a serpent ready to strike — that made me instinctively step back.

"You are late," he said quietly, turning back into the darkness of the stable without another word. "Follow me. And do not touch anything unless I tell you to."
