<nc-section data-title="Version 1" data-color="red"> Near the stables, I reined Thunder to a halt. A broad-shouldered knight in a weathered crimson cloak waited beneath the lanterns, one hand resting on the pommel of his sword. “You must be Frederick,” he said, studying me with stern gray eyes. “I am Sir Roland. Welcome to Castle Valewatch.” Before I could answer, Thunder snorted and pawed the ground. Sir Roland’s severe expression softened. “A spirited horse,” he remarked. “Let us hope his rider possesses equal courage.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable yard smelled of hay, leather, and woodsmoke. As I dismounted, a knight emerged from between the stalls, carrying an armful of oats. His silvered hair and scarred face made him look fearsome, but his smile was warm. “Frederick!” he called. “Sir Roland, at your service—though around here, you’ll soon learn that squires do most of the serving.” He set down the oats and clasped my forearm in greeting. “Come. We’ll see to Thunder first. A knight who neglects his horse rarely lives long enough to regret it.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> I had nearly reached the stables when a dark figure stepped into Thunder’s path. The stallion reared, and I fought to keep my seat. “Steady!” the stranger commanded. At once, Thunder dropped to all four hooves. The man wore a battered suit of mail beneath a blue surcoat, and an old burn scar crossed his jaw. “Sir Roland?” I asked. “The same.” His gaze shifted from me to the shadowed castle towers. “You have arrived at an ill-fated hour, Frederick. Something was seen above the northern mountains last night—something with wings.” A distant roar rolled across the darkening sky. </nc-section>
