<nc-section data-title="Version 1" data-color="red"> Near the stables, Frederick swung down from Thunder’s saddle just as a broad-shouldered knight stepped from the shadows. His polished armor bore the crest of a silver hawk. “You must be Frederick,” the knight said, offering a gauntleted hand. “Sir Roland. I’ve been told to make a squire of you—though first, I’ll see whether you can manage a horse without falling beneath its hooves.” Thunder snorted as if he understood. Sir Roland’s stern expression softened into the hint of a smile. “Come along, lad. The castle has a way of testing newcomers before breakfast.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable doors stood open, spilling the warm scents of hay and leather into the evening air. A knight in a green cloak waited beside them, one hand resting on the neck of a dappled mare. “Frederick?” he called. “I’m Sir Roland. Welcome to the castle.” He glanced at Thunder, then at the dust on Frederick’s boots. “A long ride, by the look of you. The stablemaster will see to your horse. You and I have more important matters to discuss—starting with why the old watchtower has been shining after dark.” Before Frederick could answer, a pale light flickered in the tower window. </nc-section> <nc-section data-title="Version 3" data-color="blue"> Frederick led Thunder toward the stables, where a knight stood waiting beneath a blue-and-gold banner. The man was older than Frederick had expected, with silver at his temples and a sword worn smooth at the hilt. “Sir Roland,” he said, bowing slightly. “You’ve arrived just in time.” “For what?” Frederick asked. Sir Roland’s gaze shifted to the western sky. Far beyond the castle walls, a ribbon of smoke curled above the hills. “For the reason the gates were closed,” the knight replied. “Something has awakened in the mountains—and the king will want every able hand at his side.” </nc-section>
