<nc-section data-title="Version 1: The Stern Welcome" data-color="red"> As I swung down from Thunder's saddle, my boots hitting the cobblestones with a dull thud, a figure emerged from the stable shadows. Sir Roland stood with arms crossed, his armor gleaming even in the dim light. "Squire," he called out, his voice gravelly and firm. "You ride like you're fleeing something, not arriving to serve." He stepped closer, inspecting my travel-worn cloak with a critical eye. "Discard those rags. A knight's training begins with discipline, not ceremony. The stables need mucking before dawn, and your bed is straw, not silk." He turned on his heel, pauldrons clicking like armor against armor. "Follow, or don't. But know that half the boys who arrive here wash out before winter. The rest become men." </nc-section> <nc-section data-title="Version 2: The Gentle Mentor" data-color="green"> I had just loosened Thunder's girth when a hearty laugh rang out from the stable doorway. "Well now, that's a fine beast you've got there, lad!" Sir Roland strode out, his weathered face crinkling into a warm smile that reached his kind eyes. He clapped me on the shoulder, nearly knocking me off balance. "Thunder, is it? Good name. Reminds me of old Brutus, my first mount forty years past." He helped me rub down the horse, showing me the proper way to curry the coat with practiced hands. "Don't let the stone walls fool you—this castle's got a heart, and so do its people. Come, let me show you where you'll sleep, and I'll tell you about the morning drills. We've got work to do, but we do it together, aye?" As the last light faded, he draped a woolen cloak over my shoulders. "Rest well, Frederick. Tomorrow, you begin." </nc-section> <nc-section data-title="Version 3: The Oath-Bound Shadow" data-color="blue"> The stable door creaked open before I could call out, and a man stepped into the fading light—tall, gaunt, with a silver scar tracing his jawline like a lightning bolt. Sir Roland. His eyes, pale as winter moons, fixed on me with unsettling intensity. "You've arrived," he said, and his voice carried the weight of centuries. "The last dragon's bloodline wakes, and the old knights stir in their graves." He gestured to the shadows where Thunder stamped nervously, nostrils flaring. "Your horse knows. They always know." He reached out, not to shake my hand, but to touch Thunder's forehead, murmuring words in a tongue that made the air shimmer. When he turned back to me, his gaze was heavy with warning. "Training begins at midnight, squire. Not dawn. The darkness holds lessons the sun cannot teach." Behind him, in the deepest part of the stable, something massive shifted in its sleep, and the temperature dropped ten degrees. </nc-section>
