<nc-section data-title="Version 1: The Weight of Steel" data-color="red"> I had barely dismounted when a shadow fell across the stable yard. Sir Roland stood with his arms folded, a man carved from the same granite as the castle walls. His armor was dull and battle-worn, not the polished plate of tourney knights, and a long scar split one eyebrow like a dry riverbed. "So," he said, and the word landed heavy as a dropped anvil. "Another lord's son sent to play at soldiering." I opened my mouth to correct him — I was no lord's son — but his gaze had already moved to Thunder, assessing the stallion's legs, his wind, his temper. "Groom your own horse," Sir Roland said. "Feed him. Muck his stall. If you cannot care for the beast that carries you, you will never care for the men who follow you into the dark." He turned and walked toward the armory without looking back. I stood in the straw, reins still in my hand, and understood for the first time that the castle gates had closed behind me — and that whatever I had been before, it ended here. </nc-section> <nc-section data-title="Version 2: A Hand Extended" data-color="green"> The stable smelled of hay and horse sweat, and I was so tired from the road that I nearly walked straight into the knight who stepped from between the stalls. He caught my shoulder before I could stumble — a firm grip, but gentle. "Easy, lad. There's no battle here yet." Sir Roland smiled, and the years fell off his face. He was perhaps forty, weathered but kind around the eyes. "Frederick, is it? Your father wrote ahead. Said you'd be arriving with more courage than sense." I flushed. He only laughed, a low, easy sound, and nodded toward Thunder. "He's a fine animal. You've kept him well on a hard road — that tells me something about you already." He took the reins himself and began to walk the stallion cool, murmuring to him in a voice that was clearly used to calming frightened things. "Come," he said over his shoulder. "There's stew in the kitchens and a bed in the squires' hall. Training begins at dawn, but tonight you eat." </nc-section> <nc-section data-title="Version 3: What the Lantern Showed" data-color="blue"> Sir Roland was waiting by the stable door, and he had not lit a lantern. He stood in the blue dusk with his hands behind his back, perfectly still, as though he had been there for hours — as though he had known the exact moment I would arrive. "You rode through the eastern woods," he said. It was not a question. I nodded. "The road was shorter." "The road," Sir Roland repeated, softly. "There is no road through those woods, boy. Not for eleven years." He finally stepped forward, into the last light, and I saw that his left hand was gloved in black leather and that he never once moved it. "Yet you came through unmarked. That is... interesting." Thunder shied from him — my steady, fearless Thunder — and pressed against the far wall of the yard. Sir Roland did not seem to notice. He was looking at me the way a man looks at a door he has been told never to open. "Stable your horse," he said. "And Frederick — the west tower is closed. Whatever you hear from it at night, you do not go up." </nc-section>
