<nc-section data-title="Version 1: The Red Dawn" data-color="red"> As I approached the stables, a tall figure clad in shining armor stepped out from the shadows. Sir Roland, the legendary knight of the realm, his sword gleaming in the fading light, greeted me with a nod. "You must be Frederick," he said gruffly, his eyes piercing. "Follow me; there's much to prepare before dawn." </nc-section> <nc-section data-title="Version 2: The Verdant Greeting" data-color="green"> Near the bustling stables, Sir Roland leaned casually against a wooden post, a warm smile softening his stern features. "Welcome to the castle, young Frederick," he said kindly, extending a calloused hand. "Let me show you where your steed will rest and introduce you to the duties you'll soon undertake." His friendly tone eased the nervous knots in my stomach. </nc-section> <nc-section data-title="Version 3: The Blue Evening" data-color="blue"> As I arrived at the stables, a calm figure in chainmail approached, his eyes twinkling with quiet confidence. Sir Roland nodded approvingly as he stepped forward. "Ah, Frederick," he said softly, voice steady like a flowing stream. "Your journey begins here. Come, let me guide you to your new companions and tell you what awaits in these halls." The dusk cast a peaceful hue around us. </nc-section>
