<nc-section data-title="Version 1" data-color="red"> Near the stables, a knight in a scarlet cloak waited beneath the castle’s fluttering banners. He was broad-shouldered and silver-haired, with a sword at his hip and a kindly glint in his eyes. “Frederick, I presume?” he called as I swung down from Thunder’s saddle. “I’m Sir Roland. Welcome to the castle.” I bowed, trying not to stumble over my travel-worn boots. Sir Roland clasped my shoulder, then glanced at the horse. “Good seat,” he said. “And a fine mount. Come along, lad. Your training begins at dawn—and the castle has a way of making sure no one sleeps through it.” </nc-section> <nc-section data-title="Version 2" data-color="green"> I had barely led Thunder toward the stable doors when a knight stepped out from the shadows. His armor was polished bright, though a small green plume nodded from his helm. “Frederick?” he asked. “Sir Roland, at your service.” He took Thunder’s reins with an easy familiarity and spoke softly to the stallion until its tossing head grew still. “You’ve had a long ride,” Sir Roland said. “The stable hands will see to your horse. I’ll show you where you’re to sleep—and, if you’re wise, where the kitchen keeps its best pies.” For the first time since leaving home, I felt the tightness in my chest ease. Perhaps the castle would not be such a frightening place after all. </nc-section> <nc-section data-title="Version 3" data-color="blue"> A figure emerged beside the stables, where lanternlight painted the cobbles gold. The knight wore a blue sash over his chain mail and carried himself with the calm certainty of someone who had faced many a storm. “You must be Frederick,” he said. “Sir Roland. I was told to expect you.” I offered a nervous greeting. He answered with a brief smile, then studied me—not unkindly, but as if weighing the journey in my dusty cloak and tired eyes. “Your first task is simple,” he said, pointing to Thunder. “Make certain your horse is cared for before you think of your own supper. A good knight begins by looking after those who trust him.” I nodded and led Thunder into the stable, already sensing that Sir Roland’s lessons would begin long before the first sword was drawn. </nc-section>
