<nc-section data-title="Version 1" data-color="red"> As I dismounted near the stables, the clank of steel on cobblestone announced an approaching figure. A mountain of a man in polished plate armor stood before me, his face a mask of stern lines and battle-worn scars. A thick, grey-streaked beard framed a mouth set in a permanent frown. This was Sir Roland, the Master of Squires. His gaze was like a physical weight, pinning me in place. "You are the boy, Frederick?" he grunted, his voice a low rumble like grinding stones. He didn't offer a hand, merely gestured towards the stable boy with a gauntleted fist. "See to your horse. Your duties begin at dawn. Do not be late." </nc-section> <nc-section data-title="Version 2" data-color="green"> I had just swung my leg over Thunder's back when a hearty laugh echoed from the stable's entrance. A broad-shouldered man with a welcoming smile and eyes that crinkled at the corners strode towards me. He wore a simple leather jerkin, his sleeves rolled up to reveal strong, weathered arms. "You must be Frederick! A fine beast you have there," he said, clapping me warmly on the shoulder and giving Thunder an appreciative pat on the neck. "I am Sir Roland. It's a pleasure to finally meet you. Come, let's get your horse settled, and then we'll find you a hot meal. You look like you've had a long journey." </nc-section> <nc-section data-title="Version 3" data-color="blue"> After I dismounted, a stillness settled over the stable yard, a feeling of being watched. I turned and saw a man leaning against the shadowy archway of the stables, arms crossed over his chest. He was lean, with dark hair and a hawk-like intensity in his eyes that seemed to see right through me. He pushed himself off the wall and approached with a silent, measured gait. "The roads are dangerous for a boy traveling alone," he said, his voice quiet but carrying a sharp edge. He circled me once, his gaze appraising, lingering on the worn hilt of my father's sword. "I am Sir Roland. Tell me, Frederick, what is it you truly seek within these walls?" </nc-section>
