<nc-section data-title="A Stern Welcome" data-color="red"> Sir Roland stood rigid as an iron gate before the stable entrance, his scarred hand resting upon the pommel of his broadsword. His eyes, cold and grey as winter stone, swept over me with visible disdain. "You're late," he growled, the words scraping like gravel. "The castle has no use for squires who cannot keep time. Stow your horse and report to the armory. We'll see if you've the mettle to last the week." </nc-section> <nc-section data-title="A Gentle Hand" data-color="green"> Sir Roland emerged from the stable with a warm, easy smile, brushing hay from his tunic. He was older than I'd imagined, his beard streaked with silver, but his eyes sparkled with quiet mirth. "Ah, young Frederick! We've been expecting you." He reached up and clasped my hand as I dismounted. "Come, let's see to your horse together. A squire who tends his mount with kindness will never want for a loyal friend." </nc-section> <nc-section data-title="A Rushed Encounter" data-color="blue"> Sir Roland strode towards me with quick, clipped steps, barely glancing up from the parchment clutched in his gauntleted hand. "Frederick? Good, good. The steward will assign you quarters, and the stablemaster can handle the horse." He paused, squinting towards the western tower where a bell had begun to toll. "Trouble on the border. I've no time for pleasantries. Make yourself useful—find the captain of the guard and tell him Sir Roland rides within the hour." And with that, he was gone, his cloak billowing behind him. </nc-section>
