<nc-section data-title="Version 1: Sir Roland's Stern Welcome" data-color="red"> As I approached the stables, a figure in gleaming armor stepped forward. His broad shoulders and weathered face spoke of countless battles. "You must be the new squire," he said, his voice as firm as iron. "I am Sir Roland. Stow your horse properly—discipline starts here." He watched me with piercing eyes, measuring my every move, as I led Thunder into the shadowed stall. </nc-section> <nc-section data-title="Version 2: A Friendly Greeting" data-color="green"> Just as I dismounted, a knight with kind eyes and a warm, booming laugh strode up beside me. "Welcome, lad! Frederick, is it?" he asked, extending a gauntleted hand. "I’m Sir Roland, and you’ll find the stables are the heart of our castle. Thunder’s a fine steed. Let’s get him settled together, shall we?" His easy smile made my nerves fade. </nc-section> <nc-section data-title="Version 3: Shadows at Sunset" data-color="blue"> Near the fading light of the stables, a tall knight stepped out from the shadows, his dark cloak billowing. "Frederick, I presume?" he queried, with a voice low and mysterious. "I am Sir Roland, and these grounds shall be your test and your home." He motioned for me to follow as horses snorted behind us, and I caught a glimpse of something strange in his eyes—an old sorrow, perhaps, or a secret waiting to be shared. </nc-section>
