<nc-section data-title="Version 1: The Crimson Greeting" data-color="red"> Sir Roland, clad in a gleaming suit of armor trimmed with red velvet, awaited me by the stables. His presence was imposing, yet his eyes held a spark of warmth. As I slid down from Thunder’s saddle, Sir Roland extended a gloved hand. “Welcome to Greyhaven, Frederick,” he said, his voice steady but kind. “We have much to teach you, and even more for you to prove.” He nodded towards the waiting squires and the neatly kept horses, inviting me to take my first steps in this new chapter. </nc-section> <nc-section data-title="Version 2: The Emerald Encounter" data-color="green"> The earthy scent of hay filled the air as I led Thunder towards the stables. There, beneath the sprawling branches of an ancient oak, stood Sir Roland. Dressed in a cloak the color of forest moss, he watched with a thoughtful gaze. “Frederick, isn’t it?” he called, his voice carrying the timbre of command softened by wisdom. I nodded, nerves prickling at my skin. Sir Roland smiled faintly, gesturing to the rows of horses. “Stables are where all great knights begin, lad. Come, I’ll show you your duties.” </nc-section> <nc-section data-title="Version 3: The Azure Introduction" data-color="blue"> A crisp breeze swept through the yard as I dismounted, Thunder snorting impatiently. By the stable doors, a tall man with a blue surcoat awaited me—Sir Roland himself. His gaze was piercing, his posture regal. “Frederick, welcome,” he declared. “I trust your journey wasn’t too arduous.” I shook my head, standing straighter beneath his scrutiny. Sir Roland motioned me closer. “A good squire is a knight’s shadow. Stay close, watch, and learn. Now, let us see to your horse. First impressions matter in both men and beasts.” </nc-section>
