<nc-section data-title="Version 1" data-color="red"> As Frederick dismounted Thunder near the castle stables, the heavy scent of hay and leather filled the air. A broad-shouldered man in gleaming plate armor stepped forward from the shadows of the stable doors, his silver hair catching the last rays of sunset. "Ho there, young squire," the knight called out with a voice like rolling thunder. "I am Sir Roland, master of these grounds. You've made good time from the provinces. Tell me, does that stallion of yours live up to his name, or is he as green as you look?" </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick led Thunder by the reins toward the stables, his boots crunching on the gravel path. Before he could tie off the horse, a figure emerged from the stable's interior—a knight whose armor bore the scars of many battles. Sir Roland's stern face broke into a slight smile as he regarded the newcomer. "Frederick, I presume? The stable master mentioned your arrival. I'm Sir Roland, and it falls to me to see that raw talents like yours are properly tempered before they break under pressure. Come, let's see to your mount first." </nc-section> <nc-section data-title="Version 3" data-color="blue"> The castle stables loomed before Frederick as he slowed Thunder to a trot. No sooner had he reached the mounting block than a formidable knight appeared, wiping his hands on a cloth stained with saddle oil. "Well met, lad," said Sir Roland, his deep blue eyes appraising Frederick from beneath a scarred brow. "I am Sir Roland of the Silver Gauntlet. The roads have been kind to bring you here before nightfall. Few squires arrive with such a fine steed. Tell me your name properly and we'll see about getting you settled in these halls." </nc-section>
