<nc-section data-title="Version 1: The Trial of Iron" data-color="red"> Frederick dismounted near the stables, his muscles aching from the long journey. Out of the shadows of the wooden stalls stepped Sir Roland. He was a giant of a man, scarred from a dozen campaigns, his eyes sharp as daggers. He didn't offer a hand, only a gruff appraisal. "So, you're the boy they sent me," Roland growled, tapping the hilt of his heavy broadsword. "You look soft, squire. The road is easy; the training yard is unrelenting. Let's see if you survive the week." </nc-section> <nc-section data-title="Version 2: The Smell of Hay and Leather" data-color="green"> As Thunder trotted to a halt by the paddock, a man in a simple leather tunic, his hands stained with saddle soap, looked up from a hoof he was inspecting. Sir Roland smiled warmly, wiping his hands on a rag as he approached. "Welcome to the keep, Frederick," the knight said, his voice deep and comforting. "A good rider always cares for his beast first. Rub Thunder down, feed him some oats, and then we shall speak of your duties. A knight’s foundation is built on quiet service, not just loud glory." </nc-section> <nc-section data-title="Version 3: The Call of Chivalry" data-color="blue"> Frederick brought his horse to a gentle stop near the magnificent stone arches of the royal stables. Waiting there, draped in a deep blue surcoat bearing the crest of the silver dragon, was Sir Roland. He stood with impeccable posture, the very picture of martial grace. "Ah, Frederick," Sir Roland greeted, bowing slightly with courtly elegance. "We have anticipated your arrival. The path you embark upon today is none other than the sacred pursuit of honor. Hand your steed to the stablehands, squire, and let us begin your transition from boy to guardian of the realm." </nc-section>
