<nc-section data-title="Arrival at the Stables - Version 1" data-color="red"> As I dismounted Thunder in the shadow of the stables, a tall figure emerged from the hay-scented gloom. Sir Roland, the local knight, his armor glinting in the dying light, extended a gauntleted hand. "Welcome, young Frederick," he boomed, his voice like rolling thunder. "You've come to the right place for forging a warrior's soul. Tend to your mount first—loyalty starts with the beasts that carry us." </nc-section> <nc-section data-title="Arrival at the Stables - Version 2" data-color="green"> Thunder's hooves crunched on the gravel as I led him into the stables, the air thick with the scent of fresh straw and horse sweat. From a nearby stall, Sir Roland stepped forward, his weathered face breaking into a rare smile beneath his bushy mustache. "Frederick, lad," he said warmly, clapping a hand on my shoulder. "The castle's been awaiting a squire with fire in his eyes like yours. Let's get that beast settled, then I'll show you the ropes—no time to waste on dawdlers here." </nc-section> <nc-section data-title="Arrival at the Stables - Version 3" data-color="blue"> Dismounting wearily after the long ride, I secured Thunder to a post outside the stables when a shadow fell across me. Sir Roland, broad-shouldered and scarred from countless battles, approached with measured strides. "So, you're the new squire, Frederick," he greeted curtly, his eyes appraising me like a blade at the forge. "Impressive journey, but impressions fade—prove your mettle starting now. Brush down that horse; a knight's honor is only as strong as his squire's diligence." </nc-section>
