<nc-section data-title="Version 1: A Stern Welcome" data-color="red"> As I dismounted in the shadow of the great stone stables, the heavy smell of straw and leather filled my senses. A tall figure stepped out from the gloom, his armor clanking with every deliberate step. It was Sir Roland. His face was weathered, scarred by years of border campaigns, and his cold gray eyes swept over me with immediate disapproval. "You're late, squire," he barked, not offering a hand. "Here in the high keep, we rise before the sun and we do not coddle boys who ride like tourists. Stable your beast, then report to the armory. Your training begins tonight." </nc-section> <nc-section data-title="Version 2: An Expert's Eye" data-color="green"> I led Thunder toward the paddock, my boots squeaking on the damp cobblestones. A robust man with a thick, iron-gray beard was leaning against the wooden railing, chewing on a piece of sweetgrass. Sir Roland. He watched me soothe the high-strung stallion with a quiet, practiced gaze. "A fine beast," Roland said, his voice deep and resonant. He stepped forward, patting Thunder's neck before offering me a firm, welcoming hand. "A bit too spirited for a novice, perhaps, but it shows you have courage. Welcome to the castle, Frederick. Let us see if we can fashion that courage into something unbreakable." </nc-section> <nc-section data-title="Version 3: The Weary Veteran" data-color="blue"> The stable boy ran forward to take Thunder’s reins, but a sharp whistle halted him. Out from the carriage house walked Sir Roland, wiping grease and dirt from his hands with a ragged cloth. He looked less like the legendary knight of the ballads and more like a tired blacksmith. He offered me a weary but genuine smile. "Ah, the new boy. Frederick, is it?" He sighed, looking at my pristine, unused gear. "They never send them with broken-in boots. Well, let's get you settled before the Lord Commander sees you looking so fresh. Survival around here is about keeping a low profile, lad. Come along." </nc-section>
