<nc-section data-title="Version 1" data-color="red"> Thunder slowed to a proud trot as Frederick approached the stables. A broad-shouldered knight waited beneath the lanterns, one gloved hand resting on the pommel of his sword. “You ride as though the wind owes you a favor,” he said, his stern face softening into a smile. “I am Sir Roland. Welcome to the castle, young Frederick.” Frederick dismounted and bowed, hoping the knight could not see how tightly his hands trembled. “I am ready to serve, sir.” “We shall see,” Roland replied. From within the darkened stable came a deep, unfamiliar growl. “Your training begins sooner than you think.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Near the stables, Frederick found an older knight helping a stable boy calm a frightened mare. The man wore a weathered green cloak over his armor, and a pale scar crossed his chin. “You must be Frederick,” he said, offering the mare a piece of apple before turning. “Sir Roland, at your service—and, from this day onward, your instructor.” Frederick bowed awkwardly. “It is an honor, sir.” “Honor is easy at sunset,” Roland said, taking Thunder’s reins. “We will discover what remains of it before dawn.” Yet there was kindness in his eyes as he led Frederick toward the warm light of the stable. </nc-section> <nc-section data-title="Version 3" data-color="blue"> Frederick had scarcely reached the stable yard when a knight stepped from beneath the stone archway. His silver armor reflected the last blue light of evening, and the crest upon his cloak—a winged sword—marked him as one of the king’s sworn guardians. “Frederick?” he asked. “Yes, sir.” “I am Sir Roland.” The knight studied him, then glanced at Thunder. “You arrived quickly. That may be courage, impatience, or poor judgment.” Before Frederick could answer, a horn sounded from the northern tower. Roland’s expression darkened. “Leave your horse,” he commanded. “Something has been sighted beyond the walls, and every squire in this castle is about to learn why the old watchfires still burn.” </nc-section>
