<nc-section data-title="The Encounter at the Stables - Version 1" data-color="red"> As I eased Thunder to a stop near the stables, a tall figure clad in gleaming armor stepped forward. His presence was commanding, and the emblem of a dragon emblazoned on his breastplate caught the fading light. "Welcome, Frederick," the knight said with a nod. "I am Sir Roland, your guide and mentor in the ways of knighthood. Come, there is much to learn, and the castle awaits." </nc-section> <nc-section data-title="The Encounter at the Stables - Version 2" data-color="green"> Just as Thunder settled beside the wooden post, a robust man in polished armor approached, a warm smile on his weathered face. "You must be Frederick," he said, extending a firm hand. "I am Sir Roland. If it’s training you seek, I shall be your companion in the hard road ahead. But first, let us attend to your mount—he looks as ready as you to face the trials to come." </nc-section> <nc-section data-title="The Encounter at the Stables - Version 3" data-color="blue"> Near the shadowed stables, cloaked in the last rays of sunlight, a knight emerged quietly. His armor bore the marks of many battles, yet his gaze was gentle. "Frederick," he greeted, voice calm but resolute. "I am Sir Roland. It is good fortune that has brought you here. Together, we will uncover the secrets of this fortress and perhaps, that of the last dragon itself." </nc-section>
