<nc-section data-title="Version 1: The Stern Welcome" data-color="red"> I reined in Thunder just as the drawbridge groaned overhead, the iron chains rattling like the bones of some great beast. A figure emerged from the stable archway—broad-shouldered and silver-haired, his armor polished to a mirror shine even in the dimming light. Sir Roland. I had heard the tales: the Knight of the Eastern Marches, slayer of the Thornwood Rebellion. He did not smile as he approached, his boots crunching against the gravel. "Squire," he said, his voice gravel scraped against stone. "You ride like a man fleeing his past. A knight rides toward his purpose. Dismount. Properly." He held out a gauntleted hand, not to help me down, but to steady Thunder, his eyes scanning my posture with the critical gaze of a man who had seen too many boys die in training. </nc-section> <nc-section data-title="Version 2: The Warm Greeting" data-color="green"> The castle bells were ringing vespers when I finally guided Thunder into the courtyard, my legs aching from the long ride. I expected fanfare, or at least a page to take my horse, but instead I found a man leaning against the stable door, whittling a piece of wood with a pocketknife. He looked up as I approached—not with suspicion, but with the easy grin of a man who had been expecting company. "Frederick, was it?" he called out, standing and wiping his hands on his leather apron. "Welcome to Thornhaven. I'm Sir Roland." He clapped me on the shoulder, his grip firm but kind, and gestured toward the hayloft. "Put Thunder up yourself—best way to learn a horse's temperament. And Frederick? Save me a slice of that bread in your saddlebag. I haven't eaten since dawn, and the cook's gone home early." He winked, already turning back to his carving, as if welcoming a squire was the most natural thing in the world. </nc-section> <nc-section data-title="Version 3: The Shadowed Meeting" data-color="blue"> The sun had bled out across the horizon, leaving the castle in bruised purples and deepening shadows, when I heard the rasp of steel against leather. From the mouth of the stable—a cavernous darkness that smelled of hay and old magic—stepped a man who seemed to carry the twilight with him. Sir Roland. But he looked nothing like the paintings in the great hall; his armor was mismatched, scarred, and his face was half-hidden beneath a hood that cast his eyes into shadow. "You're late," he said, his voice carrying an odd echo, as if speaking from the depths of a well. He stepped closer, and I noticed the claw marks across his breastplate—deep gouges that had nearly split the steel. "The stables were built in the time of the Last Dragon, boy. They say the stones here remember fire." He extended a hand, not to shake, but to point at the darkness beyond the stalls. "Your training begins now. But first, tell me—do you hear them? The old songs? They've been getting louder lately." </nc-section>
