My horse, a majestic stallion named Thunder, galloped across the open field. The wind whipped through my hair as I rode towards the castle gates. The sun was setting, casting a warm glow over the stone walls. I could see the banners of the kingdom fluttering in the breeze.

<nc-section data-title="Version 1" data-color="red"> As Frederick dismounted, a figure emerged from the deepening shadows of the stable archway. He was a mountain of a man, encased in dented, soot-blackened steel that had clearly seen its share of battles. A thick, grey-streaked beard covered a jaw that looked as though it were carved from granite, and his eyes, like chips of ice, missed nothing. "You must be the new whelp," his voice was a low growl, like stones grinding together. "I am Sir Roland. Don't expect any coddling here. Your horse is your life, second only to your sword. See to it before you even think of finding your own supper." He didn't offer a hand, merely a curt, dismissive nod before turning his gaze to the towering castle walls, as if Frederick were already a forgotten detail. </nc-section> <nc-section data-title="Version 2" data-color="green"> A hearty laugh echoed from the stables as Frederick swung his leg over Thunder's saddle. A knight with a warm, weathered face and a smile that crinkled the corners of his eyes strode forward, his hand outstretched. His armor was well-kept but practical, and he moved with an easy, confident grace. "Welcome, lad! You must be Frederick. I'm Sir Roland," he boomed, his grip firm and reassuring. "That's a fine beast you've got there. Come, let's get him settled in. The stable boys will see to his needs. You look like you've had a long ride; the cook's kept a hot meal waiting for you." He clapped Frederick on the shoulder, a gesture of genuine welcome that instantly eased the young squire's nerves. </nc-section> <nc-section data-title="Version 3" data-color="blue"> Frederick had just taken the reins to lead Thunder into the stables when a voice, smooth and quiet as polished steel, cut through the evening air. "The sun sets on your old life, boy." Leaning against a wooden post, almost one with the shadows, was a knight. He wasn't as large as the legends described, but he possessed a coiled stillness that was far more intimidating. His face was sharp, impassive, and his gaze was unnervingly direct, seeming to weigh and measure Frederick in a single glance. "I am Sir Roland," he said, pushing himself off the post without a sound. "They say you have a quick mind. We shall see. The stables are this way. Do not be late for supper; punctuality is a courtesy, and here, it is also a virtue." He turned and walked away, not looking back to see if Frederick followed. </nc-section>
