<nc-section data-title="Version 1" data-color="red"> I reined Thunder to a walk beneath the gatehouse and followed the smell of hay toward the stables. A broad-shouldered knight stood beside the doors, rolling up his sleeves. “Frederick?” he called. I straightened in the saddle. “Yes, sir.” “Sir Roland. Welcome to your new home.” He caught Thunder’s bridle as I dismounted, then glanced at the stallion’s lathered neck. “A fine horse. Next time, save the galloping for when something is chasing you.” My cheeks warmed. “Yes, Sir Roland.” His stern expression softened. “Water him, rub him down, and find yourself some supper. Training begins at dawn.” Beyond the stable roof, the castle’s highest tower caught the last red light. Something enormous shifted behind its shuttered windows. I looked again, but Sir Roland had stepped between me and the tower. “Your horse first, lad.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Thunder had scarcely reached the stables when a man in a battered breastplate emerged carrying a bucket in each hand. “You must be Frederick,” he said. “Either that, or the king has started recruiting horses and you’re merely the delivery boy.” I slid awkwardly from the saddle. “Frederick, sir. Reporting for training.” “Sir Roland,” he replied, setting down the buckets. “Local knight, occasional stablehand, and—until you learn which end of a sword to hold—your greatest inconvenience.” He offered his hand. His grip was firm, his smile unexpectedly kind. “Did you have a good journey?” “Yes, sir.” “Keep that answer ready. Tomorrow I shall ask whether you slept well, and you’ll want to lie.” Thunder nudged one of the buckets. As I bent to lift it, a low rumble passed through the courtyard, deep enough to stir the water. “Thunder?” I asked. Sir Roland glanced at the cloudless sky. “Not your horse,” he said, and handed me the bucket. </nc-section> <nc-section data-title="Version 3" data-color="blue"> A knight waited near the stables, half hidden in their long evening shadow. He wore no helmet, and a pale scar divided one eyebrow. At my approach, he stepped forward and rested a hand against Thunder’s neck. “Easy,” he murmured. Only then did I notice my horse was trembling. “Frederick?” the knight asked. “Yes, sir.” “I am Sir Roland. We expected you before sunset.” “The western road was flooded. I had to go around.” His eyes moved past me to the gatehouse. “Did anyone follow you?” “No, sir.” He studied me a moment longer, then nodded. “Welcome, Frederick. Get your horse settled. There’s a bed waiting for you above the tack room.” I began loosening Thunder’s saddle girth. Sir Roland remained beside us, watching the gates. “Is something wrong?” I asked. “No trouble inside these walls tonight,” he said. He spoke quietly, but his hand had settled on the pommel of his sword. </nc-section>
