<nc-section data-title="Version 1" data-color="red"> As I dismounted beside the stables, still catching my breath from the ride, a broad-shouldered knight in polished steel stepped out from the shadows of the hay loft. "You must be Frederick," Sir Roland said with a warm, booming laugh, clapping a gauntleted hand on my shoulder. "Welcome to Castle Drakenmoor. Come — stable Thunder, and I'll show you where you'll sleep, eat, and likely earn your first bruises tomorrow at dawn." </nc-section> <nc-section data-title="Version 2" data-color="green"> I had barely led Thunder into the stables when a stern voice cut through the smell of hay and leather. "Late, squire." Sir Roland stood with his arms crossed, his scarred face unreadable as he looked me and my dusty cloak up and down. "At this castle, we rise before the sun and we do not keep our horses waiting for care. Groom him, feed him, and then report to me — we shall see if you belong here." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Near the stables, an older knight was waiting for me as if he had known the exact hour of my arrival. "Frederick," Sir Roland murmured, glancing not at me but at the darkening hills beyond the castle walls. "I am glad you came before nightfall. Stable your horse quickly and stay close to the torches after dark — there are rumors of wings over the valley again, and I would not have you meet the last dragon unprepared." </nc-section>
