<nc-section data-title="Version 1: A Stern Welcome" data-color="red"> Sir Roland stood by the stables, his armor gleaming in the dwindling sunlight. His eyes, sharp and assessing, met mine the moment I dismounted. “You must be young Frederick,” he said, his voice as steady as a drawn blade. “We rise with the dawn. Do not keep me waiting.” Though his words were few, the weight of his authority pressed down on me as surely as any burden, and I bowed my head in silent promise. </nc-section> <nc-section data-title="Version 2: A Warm Reception" data-color="green"> As I approached the stables, a tall figure stepped forward, removing his helmet to reveal a kind smile. “Welcome, Frederick!” boomed Sir Roland, extending a firm hand. His grip was strong, but his eyes crinkled with warmth. “You’ve had a long journey, lad. Come, let’s find you some supper and show you where you’ll be sleeping. The castle’s bigger than it looks—easy to get lost on your first night.” Relief flooded me, and I followed Sir Roland into the comforting bustle of the stables. </nc-section> <nc-section data-title="Version 3: A Mysterious Encounter" data-color="blue"> Near the stables, shadows stretched long in the twilight. Sir Roland emerged from among the horses, his cloak billowing behind him. He fixed me with a calculating stare, then nodded once. “Frederick. You’re just in time. There’s more stirring in these lands than you know.” The horses whickered nervously as Sir Roland beckoned me closer. “Before you rest, walk the grounds with me. I have much to show you—and much you must understand.” An uneasy thrill shivered through me as I stepped into the unknown beside him. </nc-section>
