<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 a safe one." His hand rested on my shoulder, a gesture that felt both reassuring and commanding. The scent of hay and leather filled the air as stable boys rushed to take Thunder’s reins. </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 evening air. "You’re late, squire," Sir Roland barked, his arms crossed over his chestplate. His eyes, sharp as a hawk’s, scanned me from head to toe. "The king does not tolerate tardiness. If you’re to train under me, you’ll learn punctuality—or you’ll learn the cost of failure." He turned on his heel, motioning for me to follow. "Stables first. A knight’s horse is his most trusted companion. Treat it as such." </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 barrels, and I instinctively reached for my sword—only to freeze as the man pulled back his hood, revealing the weathered face of Sir Roland. "Easy, lad," he chuckled, though his eyes held a hint of something unreadable. "Not every shadow in these walls is an enemy... but not every friend wears their face openly either." He glanced over his shoulder, as if expecting someone—or something. "Come. There’s much you need to learn, and little time to waste." </nc-section>
