<nc-section data-title="Version 1: The Red Dawn" data-color="red"> Sir Roland, a tall and imposing figure clad in gleaming armor, approached Frederick with a stern look. "Hail, young squire," he said gruffly, clasping Frederick's shoulder firmly. "Welcome to the castle. You’ve got much to learn if you’re to serve our kingdom well." The first light of dawn cast a crimson hue across the stables, mirroring the determination in Sir Roland's eyes. </nc-section> <nc-section data-title="Version 2: The Verdant Greeting" data-color="green"> Near the bustling stables, Sir Roland, a knight known for his wisdom and kindness, greeted Frederick with a warm smile. "Ah, you must be the new squire," he said softly, extending a hand. "I am Sir Roland. Welcome to our humble keep. There is much to show you, and I will be here to guide you on your path." The lush greenery surrounding the stables whispered calm assurance as the sun shone brightly overhead. </nc-section> <nc-section data-title="Version 3: The Azure Encounter" data-color="blue"> Standing by the wooden troughs, Sir Roland observed Frederick with keen eyes. Without a word, he stepped forward and nodded approvingly. "Greetings, Frederick," he said in a steady voice. "You’ve arrived at a time of great change. I am Sir Roland, and I will be your mentor. Let us begin your journey now." The clear blue sky stretched infinitely above, reflecting the vast possibilities ahead. </nc-section>
