<nc-section data-title="Version 1: A Warm Welcome" data-color="red"> As I dismounted Thunder, a tall figure emerged from the shadows of the stables. Sir Roland, his armor gleaming even in the fading light, approached with a warm smile. "Frederick, I presume?" he said, his voice as steady as his gaze. "Welcome to Castle Blackthorn. I trust your journey was uneventful?" His hand rested on the hilt of his sword, a habit, I assumed, from years of vigilance. </nc-section> <nc-section data-title="Version 2: A Test of Mettle" data-color="green"> No sooner had my boots touched the ground than a gruff voice cut through the air. "You're late, squire." Sir Roland stood before me, arms crossed, his expression unreadable beneath the brim of his helmet. "The King does not tolerate tardiness. Prove to me you’re worth the food you’ll eat and the bed you’ll sleep in." He tossed a wooden practice sword at my feet. "Show me your skill." </nc-section> <nc-section data-title="Version 3: A Mysterious Encounter" data-color="blue"> The stables were eerily quiet as I tied Thunder to a post. A cloaked figure stepped out from behind a stack of hay bales, the hood pulled low. "Frederick," the figure said, and I recognized the voice of Sir Roland, though his tone was hushed, almost secretive. "There’s something you must know before you enter the castle. The King’s court is not as it seems." His eyes darted to the shadows as if expecting unseen listeners. </nc-section>
