<nc-section data-title="Version 1" data-color="red"> Near the stables, Frederick drew rein as a broad-shouldered knight stepped from the shadows. His silver-plumed helm was tucked beneath one arm, and a scar traced the length of his cheek. “You must be Frederick,” he said. “I’m Sir Roland, keeper of the castle’s horses—and, for the moment, your guide.” Frederick swung down from the saddle, his legs unsteady after the ride. Sir Roland glanced at Thunder, then gave an approving nod. “Fine seat for a squire,” he said. “Let’s see if you’ve got the sense to match it.” </nc-section> <nc-section data-title="Version 2" data-color="green"> A stable hand hurried out to take Thunder’s reins, but another man raised a gloved hand to stop him. Sir Roland wore a plain green cloak over his mail, and though his hair had gone gray at the temples, his eyes were sharp as a hawk’s. “Frederick?” he asked. “Yes, sir.” “Then welcome to the castle.” Roland clasped Frederick’s forearm in greeting. “The sun may be setting, but your training begins before dawn. Get your horse settled, and I’ll show you where you’ll sleep.” Frederick looked toward the high towers, suddenly aware that the castle was far larger—and more imposing—than it had seemed from the road. </nc-section> <nc-section data-title="Version 3" data-color="blue"> As Frederick led Thunder toward the stables, a knight emerged from between the stone buildings. His blue surcoat bore the castle’s silver dragon, its wings spread wide across his chest. “Frederick,” he said, as if the name had been waiting for him. “I’m Sir Roland.” The knight’s gaze lingered on the young squire, then flicked toward the darkening sky. For a heartbeat, his stern expression softened. “You’ve arrived on an unusual evening,” Roland said. “Come inside. There are things you should hear before the bells ring.” Behind them, Thunder stamped once against the cobbles, and the stable doors shuddered in the wind. </nc-section>
