<nc-section data-title="Version 1: The Stern Greeting" data-color="red"> As I led Thunder toward the stables, a figure emerged from the shadows of the arched doorway. He was a mountain of a man, clad in scarred plate armor that bore the dents of a hundred battles. His graying beard was cropped short, and his eyes—cold as winter steel—looked me up and down with open disapproval. "So you're the new whelp," he said, his voice like gravel grinding under a wagon wheel. "Frederick, son of Thomas the Miller. I've seen your file." I straightened my back and met his gaze. "Sir Roland. It's an honor, sir." "Honor?" He spat into the straw. "Honor is earned in mud and blood, boy, not handed out at the gate. That horse of yours—Thunder, is it?—he's lathered and winded. A knight who rides his mount to exhaustion before his first day of training is a knight who'll die in his first battle." Heat rose to my cheeks, but I held my tongue. Sir Roland circled me slowly, his gauntleted hand resting on the pommel of his sword. "Stable him. Feed him. Brush him down yourself—no stablehands. Then report to the training yard at dawn. If you're late, you'll clean the latrines for a fortnight." He paused at the doorway, glancing back over his shoulder. "Welcome to the castle, Frederick. Pray you survive the month." </nc-section> <nc-section data-title="Version 2: The Warm Welcome" data-color="green"> A hearty laugh rang out across the stable yard as I dismounted. "Easy there, lad! You've ridden hard—let's get this fine fellow some water before anything else." The man who strode toward me was broad-shouldered and barrel-chested, with a golden beard and laugh lines etched deep around his eyes. He wore no armor, only a simple green tunic with the castle's crest embroidered over his heart, and he moved with the easy confidence of someone who had nothing left to prove. "Sir Roland," he said, extending a calloused hand. "And you must be Frederick. Your father wrote ahead—says you've got the steadiest hands in the village and a heart twice the size of your common sense." His grin widened. "Both fine qualities in a squire, I might add." I shook his hand, surprised by the warmth of his grip. "Thank you, sir. I rode through the night to arrive before sunset." "Did you now?" Sir Roland clicked his tongue at Thunder, who nuzzled into the knight's palm as though they were old friends. "Well, let's get you both settled. The stables are this way, and I happen to know Cook saved a bowl of stew for the new arrival." He clapped me on the shoulder. "Training starts at dawn tomorrow, and I'll work you harder than you've ever been worked. But tonight? Tonight you rest. Welcome home, Frederick." </nc-section> <nc-section data-title="Version 3: The Cryptic Knight" data-color="blue"> The stable yard was empty when I arrived—or so I thought. As I swung down from Thunder's saddle, a voice drifted from the shadows between the stalls, soft and measured. "You're earlier than expected. Interesting." A knight stepped into the fading light, and I felt my breath catch. Sir Roland was older than I had imagined, his dark hair streaked with silver, but it was his eyes that held me—a pale, piercing blue, like ice over deep water. On his breastplate, half-worn away by time, I could just make out the sigil of a winged serpent. "Sir Roland," I said, bowing as my father had taught me. "Frederick, reporting for training." "Frederick." He spoke my name as though tasting it, weighing something I couldn't see. His gaze lingered on me a moment too long, then drifted to the horizon, where the last ember of the sun was sinking behind the mountains. "Tell me, boy—what do you know of dragons?" The question caught me off guard. "Only what everyone knows, sir. That they're gone. Centuries gone." "Gone." He smiled faintly, and there was something sad in it, something old. "Yes. That's what everyone knows." He turned and gestured for me to follow him into the stables. "Come. We'll stable your horse, and you'll eat, and tomorrow your training begins. But remember this, Frederick—" he paused, and those pale eyes fixed on mine, "—the world is older than the stories we tell about it. And some things do not stay gone forever." </nc-section>
