<nc-section data-title="Version 1" data-color="red"> Frederick had scarcely reached the stable yard when a broad-shouldered knight stepped out from the shadow of the barn. Sir Roland wore polished mail beneath a travel-stained surcoat, and his gray beard stirred in the evening breeze. “You must be Frederick,” he said, offering a firm hand. “The stables are the first lesson here. A squire who cannot care for his mount will never earn the trust of a knight.” He glanced toward the restless horses, then back to the young man with a stern but not unkind smile. “Come. I’ll show you where you belong.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Near the stables, Frederick was met by a man whose presence seemed to straighten the very air around him. Sir Roland, the local knight, stood with one hand resting on the pommel of his sword and the other raised in greeting. “So this is the new squire,” he said, his voice deep and measured. “I heard you arrived before supper.” He looked Frederick over, from dusty boots to travel-worn cloak. “You’ll begin with the horses. Quiet hands, clean stalls, and respect for every beast you touch. If you can manage that, lad, the rest of your training may yet be worth the effort.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> The scent of hay and leather filled the air as Frederick approached the stables, where a knight in steel-trimmed blue surcoat was waiting. Sir Roland’s expression was serious, though his eyes carried a hint of approval. “Frederick, I presume,” he said, inclining his head. “You’ve come a long road to stand here.” He gestured toward the rows of stalls, where horses stamped and snorted in the dim light. “A squire learns many things, but first he learns patience. Help my stablemaster tonight, and if you prove yourself useful, I may take an interest in your training myself.” </nc-section>
