<nc-section data-title="Version 1" data-color="red"> As I dismounted near the stables, a grizzled knight strode toward me, his scarred face unreadable. "You're late," Sir Roland grunted, the iron in his voice making my spine stiffen. He eyed Thunder with a critical gaze. "A fine mount, but a squire is only as good as his obedience. The hour of arrival was sunset. You've missed it by a full quarter." I opened my mouth to explain the fallen tree on the road, but he cut me off with a raised gauntlet. "No excuses. Your training begins now. Tend to your horse, then report to the armory. We'll see if your sword arm is as weak as your timekeeping." </nc-section> <nc-section data-title="Version 2" data-color="green"> The smell of hay and horses greeted me as I led Thunder into the stable yard. A broad-shouldered knight with kind eyes and a chestnut beard stepped out from the shadows, drying his hands on a cloth. "Welcome, young Frederick!" Sir Roland said, his voice warm like a hearth fire. "I trust the road treated you well." He patted Thunder's neck with the ease of a man who loved animals. "We've been expecting you. Come, let's get your horse settled, then I'll show you to the kitchens. You must be famished. A good knight fights best on a full belly." I felt the tight knot of nerves in my chest loosen at his easy smile. </nc-section> <nc-section data-title="Version 3" data-color="blue"> Under the lantern light of the stables, a gaunt figure waited, his cloak shifting as if stirred by an unfelt wind. Sir Roland's voice drifted across the cobblestones, soft yet carrying a strange echo. "So the last piece falls into place," he murmured, more to himself than to me. His pale eyes flicked to Thunder, then to the hilt of my father's old sword. "You carry the weight of prophecy, boy, though you do not know it. The training you seek here is not just in arms." He reached out, his cold fingers briefly touching my shoulder. "Tonight, after the castle sleeps, come to the eastern tower. There are truths you must learn before the moon wanes." </nc-section>
