<nc-section data-title="Version 1: The Stern Welcome" data-color="red"> As I dismounted, a heavy gauntlet clamped down on my shoulder. I turned to find Sir Roland looming over me, his scarred face unreadable. "You're late, squire," he growled, his voice like grinding stone. "The stables don't clean themselves, and the horses won't wait for your leisurely rides." He gestured sharply toward the muck-strewn stalls, and my heart sank. This was not the heroic welcome I had imagined. </nc-section> <nc-section data-title="Version 2: The Kindly Mentor" data-color="green"> A warm chuckle greeted me as I led Thunder toward the stables. Sir Roland emerged from the shadows of the gatehouse, his silver hair catching the torchlight. "Ah, the young Frederick arrives at last," he said, his eyes crinkling with a genuine smile. "I've heard good things from the border lords. Come, let's get your fine stallion settled, and then we'll share a meal. A squire's training is best begun on a full stomach." </nc-section> <nc-section data-title="Version 3: The Cryptic Warning" data-color="blue"> I had barely handed Thunder's reins to a stable boy when Sir Roland materialized from the twilight. He didn't look at me but stared past the castle walls, toward the distant, dragon-scarred mountains. "Frederick," he said, his voice a low and urgent whisper, "you've arrived on a cursed night. The stars are not in our favor." He clutched a small, obsidian amulet around his neck. "Forget glory. If you want to survive your service, do exactly as I say, and ask no questions." </nc-section>
