<nc-section data-title="Version 1: The Stern Welcome" data-color="red"> As I dismounted near the stone stables, boots crunching against the gravel, a towering figure stepped out from the shadows. Sir Roland, his silver armor scarred from countless skirmishes, eyed me with a critical gaze. "You're late, squire," he rumbled, his voice like grinding stones, before tossing me a stiff leather brush. "If you want to ride with the vanguard tomorrow, you can start by earning it in the muck." </nc-section> <nc-section data-title="Version 2: The Warm Reception" data-color="green"> The heavy oak doors of the stable creaked open as Sir Roland emerged, a welcoming grin splitting his weathered, bearded face. He strode over and clapped a heavy, gauntleted hand onto my shoulder, nearly knocking the wind out of me. "Ah, young Frederick! We've been expecting you," the knight boomed, gesturing to a stable hand to take Thunder's reins. "Come inside, lad. Let's get you a warm cup of cider before we talk about your sword-work." </nc-section> <nc-section data-title="Version 3: The Cryptic Warning" data-color="blue"> I led Thunder into the cavernous warmth of the royal stables, only to find Sir Roland sharpening a broadsword by lantern light. He didn't look up as I approached, his whetstone hissing rhythmically against the steel. "The horses are restless tonight, Frederick," the knight whispered, finally raising his piercing blue eyes to mine. "And they aren't the only ones. Keep your blade close; the shadows here hold more than just stray mutts." </nc-section>
