<nc-section data-title="Chapter 1: The Arrival - Version 1" data-color="red"> As I dismounted near the bustling stables, the scent of hay and horseflesh filled the air. A broad shadow fell over me. "So, you're the new squire," a deep voice rumbled, rough as worn leather. Sir Roland, a grizzled knight with a scar bisecting his left eyebrow, stepped forward. His armor, though polished, bore the marks of many battles, and his gaze was sharp, assessing. "Don't just stand there gawking, boy. See to your mount, then report to the barracks." His tone was devoid of warmth, a clear command. This was not going to be easy. </nc-section> <nc-section data-title="Chapter 1: The Arrival - Version 2" data-color="green"> My tired horse, Thunder, neighed softly as I led him towards the stable entrance. A figure emerged from the shadows cast by the setting sun, a man of moderate height and kind eyes, his smile lines crinkling at the corners. "Welcome to Wyvernstone, young Frederick," he said, his voice a warm balm after the long journey. Sir Roland, for it could be no other, extended a hand in greeting. His armor gleamed softly, and though his face showed the wisdom of years, there was an unmistakable gentleness about him. "Leave your mount to the stable hands, my boy. You must be weary. Follow me, and we'll see you settled." </nc-section> <nc-section data-title="Chapter 1: The Arrival - Version 3" data-color="blue"> I tethered Thunder near the main stable building, admiring the careful masonry, when a figure moved with practiced grace from the stable's archway. Sir Roland, impeccable in his gleaming plate, approached me with a measured pace. He was a man of quiet authority, his posture straight and his expression composed, almost regal. "Squire Frederick, I presume," he stated, his voice even and clear, resonating with a deeper register than I expected. "I am Sir Roland. Your timing is impeccable; the evening meal will soon be ready. See that your steed is properly cared for, and then I will personally escort you to your quarters." There was a formality in his greeting that spoke of tradition and duty. </nc-section>
