<nc-section data-title="Version 1: The Stern Welcome" data-color="red"> I reined Thunder in before the stable doors, my heart hammering against my ribs. A figure emerged from the shadows—broad-shouldered, scarred across his left cheek, with eyes like flint. Sir Roland. They said he had slain three men in single combat and never smiled. "Frederick," he said, not quite a greeting. "You're late. The Lord Commander expected you at dawn." His hand rested on the pommel of his sword, though he did not draw it. "Leave the beast. Come inside. We have much to discuss about what it means to wear this kingdom's steel." I dismounted, suddenly aware of how small I looked beside him, how the mud on my boots seemed an insult to the polished floor. "Yes, sir. I mean—my lord. I apologize, my lord." Roland's lip curled. "Save your breath for the training yard. Words are for poets and liars. Tomorrow, you will learn whether you are neither." </nc-section> <nc-section data-title="Version 2: The Unexpected Kindness" data-color="green"> The stable doors creaked open, and a man stepped into the lantern light—not the fearsome knight I had imagined, but someone with laugh lines around his eyes and calloused hands that spoke of honest labor. Sir Roland. He carried no sword, only a worn leather satchel and a gentle smile. "Frederick, is it? Come, come—Thunder looks magnificent, but he'll need water and rest." He clapped my shoulder with surprising warmth. "I was a squire once, you know. Terrified of everything. The castle seemed enormous, the knights seemed like giants." He led me toward a small fire already burning in the stable yard. "Sit. Eat something. Tomorrow we begin, but tonight, you are my guest. Tell me—what drew you to this life?" I found myself speaking of my father's stories, of dragons in the old tales, of wanting to be worthy of something greater than myself. Roland listened, truly listened, and when I finished, he nodded slowly. "The dragons are gone, boy. But the need for heroes remains. Sleep well. We have work to do." </nc-section> <nc-section data-title="Version 3: The Mysterious Warning" data-color="blue"> I had barely swung my leg over Thunder's back when a voice cut through the evening air—smooth as oil, cold as winter stone. "You ride well, squire. Pity about your timing." Sir Roland stood in the stable archway, silhouetted against the dying light. He wore no armor, yet something about him made my skin prickle. His eyes—pale, almost colorless—fixed on me with unsettling intensity. "There are... complications," he said, stepping closer. The stable cats scattered. "The castle you see is not the castle that was. Secrets sleep in these walls, Frederick. Old secrets. And some of them have teeth." He reached into his cloak and withdrew a small iron key, pressing it into my palm. It was warm, impossibly warm. "The east tower. Midnight. Come alone, or don't come at all—but know that others will come, and they will not be so... accommodating." He turned and walked into the darkness without another word, leaving me clutching the key, wondering if I had been welcomed or warned. </nc-section>
