My horse, a majestic stallion named Thunder, galloped across the open field. The wind whipped through my hair as I rode towards the castle gates. The sun was setting, casting a warm glow over the stone walls. I could see the banners of the kingdom fluttering in the breeze.

<nc-section data-title="Frederick arrives at the castle" data-color="red"> Frederick dismounted Thunder near the bustling stables, the scent of hay and horses filling the air. Before he could even secure his horse, a figure emerged from the shadows of an archway. "Welcome, young squire," a booming voice announced. Sir Roland, a knight of formidable build with a weather-beaten face and a kind smile, stepped into the light. "I trust your journey was uneventful?" </nc-section> <nc-section data-title="Frederick arrives at the castle" data-color="green"> Having finally reached the castle, Frederick led Thunder towards the stables. Just as he was about to tie the reins, a broad hand clapped him on the shoulder. He turned to find a man in polished plate armor, a glint in his eye. "You must be Frederick," Sir Roland said, his voice deep and reassuring. "I've been expecting you. A long ride, I imagine." </nc-section> <nc-section data-title="Frederick arrives at the castle" data-color="blue"> The castle's grandeur was even more imposing up close. Frederick steered Thunder towards the stables, eager to tend to his weary steed. As he guided the horse into an empty stall, he heard a rustle of heavy fabric. A tall, distinguished knight, Sir Roland, stood nearby, his arms crossed over his chest. "Frederick, I presume?" the knight inquired, a respectful nod accompanying his words. "Come, let us see to your horse, then you can settle in." </nc-section>
