<nc-section data-title="Version 1: The Stern Welcome" data-color="red"> I pulled back on the reins as Thunder slowed to a trot near the courtyard stables. A broad-shouldered man in scarred plate armor stood waiting by the trough, arms crossed over his chest. His beard was grey and trimmed close, his eyes sharp as iron daggers. "You're late, boy," Sir Roland barked before I could even dismount. "And you ride like a sack of oats. Down off that stallion and groom him yourself before I decide whether you're worth the bread you'll eat tonight." </nc-section> <nc-section data-title="Version 2: The Veteran's Greeting" data-color="green"> Thunder brought us to a gentle stop outside the stable doors, snorting softly in the cool dusk air. Leaning against the timber frame was Sir Roland, a veteran knight whose weathered face carried the story of a hundred battles. A warm smile broke through his thick grey beard as he stepped forward to pat my stallion's neck. "Fine beast you have there, Frederick," Sir Roland said, his voice deep and rumbling. "Welcome to the keep. Hand off your reins to young Pip; you've had a long ride, squire, and there's a warm meal waiting inside." </nc-section> <nc-section data-title="Version 3: Shadows and Steel" data-color="blue"> As Thunder trotted into the quiet shadows of the stable yard, a solitary figure stepped out from the gloom. Sir Roland wore no heraldry on his darkened surcoat, but the polished pommel of his broadsword caught the last amber rays of sunlight. He didn't speak immediately; instead, his piercing grey gaze lingered on the old dragon-crest cloak clasp at my throat before finally rising to meet my eyes. "So, the boy from the eastern marches finally arrives," Sir Roland murmured softly, his tone weighed down by heavy secrets. "Tie up your horse, Frederick. The realm is changing, and your training begins tonight—whether you are ready or not." </nc-section>
