<nc-section data-title="Version 1: The Knight's Test" data-color="red"> The stable yard was nearly empty when a figure detached itself from the shadows of the hayloft. Sir Roland was taller than I expected, his scarred face half-hidden behind a grey-streaked beard, his arms crossed over a chest broad as a barn door. "So," he said, his voice like gravel under a boot. "The new squire arrives with the sunset." He circled Thunder slowly, inspecting my horse with a critical eye, then turned that same scrutiny on me. "A squire who arrives at dusk will rise before dawn. You'll muck the stalls, polish the tack, and see to your mount before you eat a single bite of supper. Here, we earn our bread." I swallowed hard and nodded. "Yes, sir." "We'll see," he said, already walking away. "Words are cheap, boy. Show me your worth by morning." </nc-section> <nc-section data-title="Version 2: A Warm Welcome" data-color="green"> I had barely swung down from the saddle when a booming laugh rolled across the stable yard. "Ha! You must be Frederick!" Sir Roland strode toward me with arms flung wide, his weathered face split by a grin. He clapped me on the shoulder hard enough to stagger me, then ran an appreciative hand along Thunder's neck. "A fine animal," he said, and his eyes twinkled. "Though I daresay he's carried a finer rider. Come, lad—let's get him settled, and then we'll get some hot stew in you. You've the look of your father about you, did you know that? He sat a horse just the same way." As we worked side by side unbuckling the saddle, my nervousness melted away. Whatever trials lay ahead, I knew I had found a friend in this place. </nc-section> <nc-section data-title="Version 3: The Quiet Knight" data-color="blue"> The stables were silent but for the soft snuffling of horses when Sir Roland appeared. He made no sound in his approach—one moment I was alone, and the next he stood beside me, pale eyes studying me beneath a fall of dark hair. "Frederick," he said. Not a question. He knew my name before I spoke it. "Sir Roland?" I managed. He inclined his head, but his gaze drifted past me, up toward the castle's highest tower, where a faded banner stirred in the evening wind. It bore the image of a dragon, wings outspread, embroidered in thread so old it had gone silver. "The castle has been waiting for you longer than you know," he murmured. Then, as if catching himself, he took Thunder's reins from my hand. "Come. There is much you must learn—and less time than you think to learn it." </nc-section>
