<nc-section data-title="The Stern Welcome" data-color="red"> As I dismounted, the heavy thud of boots against cobblestone announced the arrival of Sir Roland. His armor, scarred and dull from years of service, caught the dying light like a warning. "You’re late, boy," he growled, his eyes narrowing as he gripped the hilt of his claymore. "The stables are for those who work, not for those who admire the horizon. Tend to your mount and report to the courtyard for discipline, not pleasantries." </nc-section> <nc-section data-title="A Mentor's Curiosity" data-color="green"> Sir Roland stepped from the shadows of the stable block, a tired smile etched into his weathered face. He reached out to pat Thunder’s flank, his leather gauntlet creaking softly. "Fine beast you've brought to my gates, squire," he said, his voice surprisingly gentle for such a hulking man. "The road from the valley is treacherous this time of year. I trust you didn’t encounter any shadows in the mountain passes? Come, lead him in; we have much to discuss before the moon rises." </nc-section> <nc-section data-title="The Weighted Expectation" data-color="blue"> The gate swung open, and there stood Sir Roland, arms crossed behind his back, staring at me with an intensity that made the air feel thin. He didn't offer a greeting, only a sharp nod toward the stable entrance. "Everyone in this castle carries a burden, Frederick," the knight murmured as I led Thunder forward. "The dragons of old are silent, but they leave ghosts in their wake. See that you don't make yourself an easy target for them. Groom your horse, then find me in the armory." </nc-section>
