<nc-section data-title="Version 1" data-color="red"> Frederick had scarcely dismounted when a broad-shouldered knight stepped out from the shadow of the stables. Sir Roland wore a weathered cloak over polished mail, and his face was stern until his gaze settled on the young squire. Then, to Frederick’s surprise, a faint smile softened the hard line of his mouth. “You must be Frederick,” Sir Roland said, extending a gloved hand. “The castle has been expecting you. Come—before the horses decide they like you better than I do.” Frederick laughed nervously and straightened his satchel. Sir Roland’s easy manner eased the tightness in his chest, and together they walked past the stable hands and the restless horses toward the heart of the keep. </nc-section> <nc-section data-title="Version 2" data-color="green"> As Frederick approached the stables, a knight in silvered armor was waiting beside the hay bales, one hand resting on the hilt of his sword. Sir Roland’s red cloak was marked by road dust, but his eyes were keen and bright as he studied the young squire. “So,” he said, voice calm and even, “you are the boy sent to serve here.” Frederick bowed quickly. “Yes, my lord. Frederick, at your service.” Sir Roland nodded once, then glanced toward the stable doors where warm light spilled across the stones. “Good. We begin with the horses, because a knight who cannot listen to a horse will never listen to the world. Come inside. Your training starts now.” Frederick followed him, feeling the weight of those words settle over him like the first true measure of his new life. </nc-section> <nc-section data-title="Version 3" data-color="blue"> Near the stables, Frederick found a knight speaking with the stablemaster in a low, steady voice. When the man turned, Frederick saw the faint scar along his jaw and the tired strength in his posture. This was Sir Roland, the local knight the servants had whispered about since morning. “You’re late,” Sir Roland said, though his tone carried more amusement than reproach. Frederick blinked. “I—I came as quickly as I could, sir.” Sir Roland chuckled and clapped him lightly on the shoulder. “Then you’ve already learned the first lesson: never arrive at a castle without expecting someone to test your nerves. Come, boy. I’ve a place to show you, and if you can keep pace, I’ll tell you what kind of squire you’re meant to be.” Frederick glanced back at the stables, where the horses shifted and snorted in the dusk, then hurried after the knight, wondering what trials awaited him beyond the lantern-lit yard. </nc-section>
