```html <nc-section data-title="Version 1: A Stern Welcome" data-color="red"> Near the stables, as Frederick dismounted and led Thunder inside, the towering figure of Sir Roland approached with clanking armor. "Welcome, young squire," the knight rumbled, his scarred face stern under the fading light. "I am Sir Roland. Your training begins at dawn—do not falter, or the realm will suffer." </nc-section> <nc-section data-title="Version 2: A Warm Greeting" data-color="green"> After securing his horse in the stables, Frederick turned to find Sir Roland waiting nearby, a broad smile breaking across his bearded face. "Ah, Frederick! I've heard of your arrival," the local knight said heartily, clapping him on the shoulder. "Welcome to the castle grounds. Come, let us speak of the dragons and duties that await you." </nc-section> <nc-section data-title="Version 3: A Formal Encounter" data-color="blue"> Frederick stood by the stables, brushing dust from his cloak, when Sir Roland strode forth from the shadows of the courtyard. "Squire Frederick, I presume," the knight intoned formally, bowing his helm slightly. "I am Sir Roland, guardian of these lands. It is my honor to greet you here and guide your path in service to the king." </nc-section> ```
