<nc-section data-title="Version 1: A Stern Welcome" data-color="red"> As I dismounted from Thunder, a gruff voice called out from the shadows of the stables. "So, you're the new squire." Sir Roland emerged, his armor clanking with each heavy step. His weathered face bore the scars of countless battles, and his eyes—cold as steel—fixed upon me with unmistakable intensity. "I am Sir Roland, and I will be overseeing your training. Let me be clear, boy: this castle holds no room for weakness. You'll work harder than you've ever worked in your life." He circled me slowly, assessing my frame like a blacksmith evaluating ore. "Your first task is to tend to the horses. Thunder looks exhausted. See that he is properly cared for, or you'll answer to me." </nc-section> <nc-section data-title="Version 2: A Measured Greeting" data-color="green"> A tall knight in polished armor approached from the stables, his movements measured and deliberate. "Welcome to Castle Thornwick, young squire," Sir Roland said warmly, extending a gauntleted hand. His face, though lined with age and experience, bore a kind smile. "I am Sir Roland, and I've been expecting you. Your reputation for dedication precedes you." He glanced at Thunder with an experienced eye. "Fine horse you have there. The stables are well-equipped, and our master of horses will see to your mount's needs." He placed a reassuring hand on my shoulder. "Training will be rigorous, but fair. Come—there is much to show you before nightfall." </nc-section> <nc-section data-title="Version 3: An Intriguing Mystery" data-color="blue"> I had just begun to lead Thunder toward the stables when a figure emerged from the dimming twilight. Sir Roland was not what I expected—younger than I'd imagined, with keen eyes that seemed to see beyond the present moment. "Frederick," he said, speaking my name as though he'd known it for years. "I've been waiting for you. There are things you should know about this castle, things that aren't spoken of openly." He glanced around, lowering his voice. "The legends of the Last Dragon—they're not mere folklore. And your arrival here, at this precise time... it may not be coincidence." He studied my face carefully. "First, we must get you settled. But tonight, after the castle sleeps, I need to show you something in the eastern tower. Can I trust your discretion?" </nc-section>
