<nc-section data-title="Version 1: The Red Dawn" data-color="red"> As I dismounted from Thunder, a tall figure approached from the shadows of the stable. Sir Roland, the castle’s seasoned knight, strode forward with a stern yet welcoming expression. His armor gleamed crimson in the dying light, and he extended a hand. "You must be the new squire, Frederick," he said softly. "The path before you is perilous, but courage shall be your guiding light." </nc-section> <nc-section data-title="Version 2: The Verdant Welcome" data-color="green"> I slid from Thunder’s back, the grass soft beneath my feet. From the shade of the stables, Sir Roland, the noble knight known for his valor, stepped forward, smiling kindly. His armor bore the emblem of a rising leaf, symbolizing growth. "Greetings, Frederick," he said warmly. "Your journey begins now, and I vow to aid you in discovering the strength within." </nc-section> <nc-section data-title="Version 3: The Azure Encounter" data-color="blue"> I lowered myself from Thunder and looked up as a tall figure emerged from the stables’ shadow. Sir Roland, clad in azure armor that shimmered like the sky on a clear day, approached with measured strides. His eyes held both sternness and pride. "Ah, Frederick," he greeted in a deep voice. "The castle has awaited your arrival. Let us see what you are made of, young squire." </nc-section>
