<nc-section data-title="Version 1" data-color="red"> Frederick had barely dismounted when a broad-shouldered knight stepped from the shadow of the stables. His steel was polished but worn at the edges, and the silver crest on his cloak caught the dying light. “You must be Frederick,” he said, his voice roughened by years of command. “I’m Sir Roland. If you mean to serve here, then you’ll learn the yard before you learn the hall.” Frederick straightened at once, struck by the knight’s stern gaze, but when Sir Roland clapped a heavy hand on his shoulder, the gesture held an unexpected warmth. “Come,” Roland added. “I’ll show you where the horses are kept—and where boys become men.” </nc-section> <nc-section data-title="Version 2" data-color="green"> As Frederick led his horse toward the stables, a knight in weathered mail emerged from the half-open doors, brushing straw from his gloves. He wore the easy confidence of a man at home among steeds, and his gray eyes took Frederick in with one quick glance. “Sir Roland,” he introduced himself, inclining his head. “You’re the new squire. Good. We’ll see whether you can keep a saddle clean and a lance straight.” Frederick managed a nervous smile, and Roland returned it with a hint of one of his own. Behind him, the stables breathed with the sounds of shifting hooves and soft nickers, as if the horses themselves were listening. “Stay close,” the knight said. “The castle has enough rules for one day; I’ll give you the ones that matter.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> Near the stables, Frederick was halted by the sound of bootsteps on stone. A knight approached with purposeful strides, his cloak dusted from the road and his helm tucked beneath one arm. The stable boys fell silent as he drew near, and even Thunder stamped once, sensing the authority in his bearing. “Frederick, is it?” the knight asked. “I am Sir Roland.” His expression was stern, but not unkind. He looked Frederick over as though measuring more than the fit of his tunic. “You’ve arrived at a fine hour. A castle teaches quickly, and the stables teach first.” Frederick bowed as best he could, feeling the weight of the moment settle on his shoulders. Sir Roland gave a curt nod. “Good. Then let us begin.” </nc-section>
