<nc-section data-title="Version 1" data-color="red"> Fredrick crested the hill and saw the castle in all its glory. He spurred his horse towards the gates and soon found himself nearing the stables. As he dismounted, a knight stepped out from the shadows of the stalls. "Ah, you must be Frederick," boomed Sir Roland, the local knight, clapping the young squire on the back. "I've been expecting you." </nc-section> <nc-section data-title="Version 2" data-color="green"> With the castle towers looming overhead, Frederick led his weary stallion into the stable area. The scent of fresh straw mingled with the evening air. Sir Roland, a seasoned knight of the realm, emerged from within and greeted Frederick warmly yet formally. "Welcome, squire Frederick. I am Sir Roland. Your journey here is just the beginning of your true test." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Riding through the arched entrance, Frederick made his way directly to the stables as instructed. The horses were restless, sensing new presence. There, awaiting him, was Sir Roland. The local knight extended a gauntleted hand and said, "Frederick, I presume? I'm Sir Roland. Let's get you settled in before your training commences at dawn." </nc-section>
