<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 cloak bore the crest of a black hawk. “You must be Frederick,” the knight said. “I am Sir Roland, captain of the castle guard.” Frederick climbed down from Thunder and bowed quickly. “At your service, sir.” Roland’s stern expression softened. He glanced at the boy’s travel-worn pack, then at the fading light beyond the walls. “Your training begins at dawn. Tonight, you eat, sleep, and learn one lesson.” “What lesson is that?” “Never trust a quiet castle.” From somewhere deep within the fortress came a low, distant rumble. Thunder stamped nervously, and the stable lanterns flickered blue. </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick had barely reached the stables when a knight emerged carrying two armfuls of hay. His polished armor was scratched, his brown cloak patched at the shoulder, and a cheerful scar ran from his chin to his ear. “Frederick?” he called. “Yes, sir.” “Sir Roland.” He dropped the hay into a stall and offered a hand instead of demanding a bow. “You’re just in time. Thunder looks as though he could eat the entire kingdom.” The stallion snorted, as if agreeing. Roland laughed. “Good. A brave horse is worth three brave men, and considerably easier to feed.” He led Frederick inside, where the warm scent of straw and leather filled the air. “Come along, lad. I’ll show you where you’ll sleep—and warn you which corridors to avoid after moonrise.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> At the stable doors, a figure waited beneath the torchlight. He wore a knight’s dark-blue surcoat and rested one gloved hand upon the pommel of his sword. “Frederick of the eastern road?” he asked. Frederick nodded. “I am Sir Roland.” The knight’s gaze lingered on the silver pendant at Frederick’s neck, the one his mother had given him before he left home. “You carry a dragon’s mark.” Frederick touched the pendant. “It belonged to my father.” “Then keep it hidden,” Roland said quietly. He stepped closer, lowering his voice. “There are ears in this castle that listen for the old names.” A cold wind moved through the stable, though every door stood shut. Beyond the walls, something cried out in the darkness—neither wolf nor bird. Roland turned toward the sound. “Come. Your arrival has been noticed.” </nc-section>
