<nc-section data-title="Version 1: The Knight's Welcome" data-color="red">
As I dismounted Thunder near the stables, a tall figure in gleaming armor approached, his boots crunching on the gravel path. It was Sir Roland, the local knight renowned for his valor in the border skirmishes. "Young Frederick," he boomed, clapping a heavy hand on my shoulder, "welcome to Castle Ebonheart. Your training begins at dawn—hope you're ready for the trials ahead." His eyes twinkled with a mix of sternness and amusement, but beneath it, I sensed the weight of the kingdom's fading magic.

<nc-section data-title="Version 2: A Cautious Greeting" data-color="green">
I led Thunder into the stables, the scent of hay and leather filling the air, when a voice called out from the shadows. Sir Roland emerged, his face weathered by years of service, a scar running down his cheek like a reminder of old battles. "Squire Frederick, is it? You've made good time from the villages," he said, his tone measured as he inspected my horse. "The castle's no place for the faint-hearted. Tend to your mount first—then we'll speak of your duties." His words carried a subtle warning, hinting at the whispers of dragon sightings that had drawn me here.

<nc-section data-title="Version 3: Warmth in the Twilight" data-color="blue">
Dismounting wearily after the long ride, I secured Thunder to a post outside the stables just as Sir Roland strode up, his cloak billowing like a banner. The knight's broad smile cut through the encroaching dusk. "Ah, Frederick! The prophecies spoke of a squire with fire in his eyes, and here you are," he greeted, offering a firm handshake that nearly crushed my fingers. "Come, lad, the evening meal awaits, but first, let's get this beast settled. The last dragon's shadow looms large—we'll need your spirit more than ever." His enthusiasm ignited a spark of excitement in my chest.
