<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 heavy with expectation. </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 there, squire! What took you so long?" Sir Roland stood with his arms crossed, his eyes sharp as a hawk’s. "The road from the village is no excuse for tardiness. If you’re to train under me, you’ll need to be swifter—and tougher." He tossed me a sack of grain. "Start by proving you can handle the simplest of tasks." </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. Then, from the dimly lit corner, a cloaked figure stepped forward. Sir Roland’s face was half-hidden by his hood, but his piercing eyes locked onto mine. "Frederick," he murmured, as if he’d been expecting me for years. "The castle has been awaiting your arrival. There are... things you must learn, and little time to waste." His tone carried a weight that sent a shiver down my spine. </nc-section>
