<nc-section data-title="Version 1" data-color="red"> Near the stables, Frederick drew Thunder to a halt. A broad-shouldered knight in a weathered crimson cloak stepped from the shadows, one hand resting on the pommel of his sword. “Frederick?” he called. “Yes, sir.” “I am Sir Roland, captain of the castle guard.” His stern expression softened as he glanced at the young squire’s travel-worn clothes. “You have arrived later than expected, but not too late to prove yourself. Take your horse inside, then report to the armory. Dawn comes early here.” Frederick dismounted, heart thudding with equal parts fear and excitement. His training had begun. </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable doors swung open as Frederick approached, spilling the warm scents of hay and leather into the evening air. A knight emerged, smiling beneath a silvered mustache. “Welcome to Castle Veyr,” he said. “Sir Roland, at your service.” Frederick bowed quickly. “I am Frederick, sir.” “So I’ve heard.” Roland took Thunder’s reins and inspected the stallion with an approving nod. “A fine beast—and a brave choice for a first journey. Care for him well, and the castle may yet come to care for you.” Before Frederick could ask what he meant, a bell rang from the tower. Roland’s smile vanished. “Come. There is something you must see before supper.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> Frederick had barely reached the stables when a shadow fell across the path. Sir Roland stood beside the lantern post, his dark armor gleaming in the twilight. “You’re the new squire,” the knight said. Frederick nodded. “Frederick of—” “Names matter less than deeds.” Roland pointed toward the stalls. “Put your stallion away, fetch a bucket, and be ready in the courtyard before the moon reaches the highest tower.” Frederick hurried to obey, though he could not resist asking, “What happens then?” Sir Roland looked toward the distant mountains, where a thin red glow flickered behind the peaks. “Then,” he said quietly, “we learn whether the old stories are waking.” </nc-section>
