<nc-section data-title="Version 1: The Knight's Welcome" data-color="red"> As I reined Thunder to a halt near the sprawling stables, a figure emerged from the shadowed archway. Sir Roland, by the gleaming silver of his breastplate and the familiar emblem on his surcoat, was even more imposing than the tales described. His face, etched with the lines of countless battles, broke into a faint smile as I dismounted. "Young Frederick, I presume?" His voice was a low rumble, yet not unkind. "Welcome to Wyvernstone. Your journey was swift." He extended a gauntleted hand, not for a handshake, but gesturing towards the stable hands already approaching Thunder. </nc-section> <nc-section data-title="Version 2: An Unassuming Greeting" data-color="green"> The rich scent of hay and horses, mingled with the earthy dampness of the stable yard, filled my nostrils as I guided Thunder towards the hitching posts. I was stiff from the saddle, my muscles aching, but the excitement of arrival surged through me. Then, a voice cut politely through the stable chatter. "A weary ride, no doubt." Turning, I saw a man, not in full battle plate but in a practical leather tunic and breeches, his sword at his hip. His brown eyes held a shrewd intelligence. "Sir Roland," he introduced himself with a nod, a friendly, almost paternal smile gracing his lips. "We've been expecting you, Frederick. See to your horse, then find me inside." </nc-section> <nc-section data-title="Version 3: Formalities and First Impressions" data-color="blue"> I dismounted at a designated stable entrance, the crunch of gravel under my boots a stark contrast to the quiet dignity of the castle walls. Almost immediately, a tall, powerfully built man stepped forward, his posture impeccable. Clad in a finely wrought chainmail shirt over a deep blue tunic, a polished sword hilt visible above his shoulder, he exuded authority. "Squire Frederick," he stated, his voice clear and resonant, a true knight's tone. "I am Sir Roland, Knight-Captain of Wyvernstone. It is an honor to finally meet the ward of Lord Eldrin." He offered a brief, formal bow, his gaze assessing but not unkind. "Your training commences tomorrow morning. For now, see to your steed and prepare for supper." </nc-section>
