<nc-section data-title="Version 1: A Stern Welcome" data-color="red"> As I dismounted near the stables, the smell of damp hay and leather filled the air. A towering figure stepped out from the shadows of the wooden awning. It was Sir Roland. His armor was scarred from battle, and his face was set in a hard, unyielding line. He didn't offer a hand, only a cold, assessing gaze that swept over me from head to toe. "You're late, squire," he growled, his voice like grinding stones. "In my service, laziness is a sin. Tend to your beast, then find me in the courtyard. Your training begins now, and I do not tolerate weakness." </nc-section> <nc-section data-title="Version 2: An Honorable Reception" data-color="green"> I led Thunder toward the stable doors, where a knight stood waiting, bathed in the amber light of the setting sun. Sir Roland was a man of noble bearing, his posture upright and his expression warm despite the deep scars of past campaigns etching his brow. As I approached, he offered a firm, welcoming nod. "Ah, Frederick. We have been expecting you," he said, his voice deep and resonant. "You have had a long journey. Let the stable boys care for your mount, and join me in the hall for a hot meal. Tomorrow we begin the hard work, but tonight, we welcome you to the brotherhood." </nc-section> <nc-section data-title="Version 3: A Practical Introduction" data-color="blue"> No sooner had I swung my leg off the saddle than a broad-shouldered man in a simple leather jerkin walked out of the stables, carrying a pitchfork. I recognized the sharp eyes and authoritative air of Sir Roland immediately, though he wore no armor. "Throw me the reins, lad," he called out, catching them with practiced ease. "The journey from the southern valleys is a brutal one, and both you and the stallion look ready to collapse. I am Roland. Let's get your gear stowed away. A good squire learns first how to care for his gear and his beast before he ever touches a sword." </nc-section>
