Here are 3 alternate prose sections that continue the story: <nc-section data-title="Version 1: Sir Roland's Greeting" data-color="red"> As I dismounted Thunder near the stables, a gruff voice called out from the shadows. "You there, squire! You must be Frederick." A towering knight emerged, his armor gleaming in the fading sunlight. Sir Roland was a bear of a man, with a thick black beard and eyes like coal. He crossed his arms and looked me up and down with a scrutinizing gaze. "You're late," he growled. "The sun has nearly set. In this kingdom, tardiness is a sign of weakness." He turned sharply on his heel. "Follow me, boy. Your training begins at dawn — if you can manage to wake yourself in time." </nc-section> <nc-section data-title="Version 2: Sir Roland's Greeting" data-color="green"> The stable hands rushed forward to take Thunder's reins as I slid from the saddle, my legs aching from the long journey. Before I could catch my breath, a warm laugh rang across the courtyard. "Frederick! By the stars, you look just like your father!" Sir Roland strode towards me with a broad smile, his silver armor catching the last light of the dying sun. He clasped my hand firmly and shook it with the enthusiasm of an old friend. "Welcome to Castle Ardenmoor, lad. I trained your father on these very grounds, and I intend to make you just as fine a knight — perhaps even finer." </nc-section> <nc-section data-title="Version 3: Sir Roland's Greeting" data-color="blue"> I was leading Thunder towards the stables when I noticed a solitary figure leaning against the wooden post, sharpening a sword with long, deliberate strokes. The knight looked up slowly, his weathered face unreadable beneath the shadow of his helm. "Frederick," he said quietly, more a statement than a greeting. Sir Roland rose to his full height, sliding the blade back into its scabbard with practiced ease. He studied me for a long moment, as if weighing something invisible. "I have heard much about you," he said at last, his voice low and measured. "Whether any of it is true..." he glanced towards the darkening sky, "...we shall soon find out." </nc-section>
