<nc-section data-title="Version 1: The Stalwart Knight" data-color="red"> I dismounted Thunder near the bustling stables, the aroma of hay and horseflesh thick in the air. Before I could even tether my steed, a figure emerged from the shadows of an archway. He was a man of impressive stature, clad in the polished steel of a knight's half-plate, a flowing crimson surcoat emblazoned with a silver lion's head over his chest. His beard was neatly trimmed, streaked with grey, and his gaze, though stern, held a flicker of welcoming warmth. "You must be Frederick," his voice was a deep rumble, resonating with authority. "I am Sir Roland. Welcome to Castle Aethelgard." </nc-section> <nc-section data-title="Version 2: A Knight's Welcome" data-color="green"> Reaching the stable yard, I handed Thunder's reins to a waiting groom, my own weary muscles protesting the long journey. As I stretched, a presence loomed beside me. A knight, his armor gleaming under the fading light, extended a gauntleted hand. Sir Roland, I presumed, judging by his bearing and the intricate design stitched into his tunic – a green dragon rampant on a field of white. He had a kind, weathered face, etched with lines that spoke of countless battles and duties. "Frederick, I presume?" he asked, his voice unexpectedly gentle. "A long journey, I imagine. Welcome, young squire." </nc-section> <nc-section data-title="Version 3: The Guardian of the Stables" data-color="blue"> The clamor of the stables grew louder as I guided Thunder towards the main entrance. Just as I was about to enter, a broad-shouldered man stepped out, dwarfing the stable boy he'd been speaking with. He wore practical, unadorned armor, a tabard of simple blue covering his chainmail, and carried the relaxed, watchful air of someone entirely at home. His eyes, keen and intelligent, fixed on me instantly. "Frederick," he stated, not asked, a slight smile touching his lips. "I am Sir Roland, Knight of the Stables. Your arrival was expected. Come, let's see to your mount and then your quarters." </nc-section>
