<nc-section data-title="The Stern Welcome" data-color="red"> As I dismounted, the heavy thud of metal boots echoed against the cobblestones. Sir Roland emerged from the shadows of the stables, his armor stained with the wear of a hundred battles. He didn't offer a smile, only a sharp glare that seemed to measure the weight of my fear. "You're late, boy," he growled, his hand resting ominous and heavy on the pommel of his sword. "In this yard, steel speaks louder than intentions. See to your beast, then fetch the whetstone. If you value your skin, don't let me find rust on a single blade by dawn." </nc-section> <nc-section data-title="A Mentor's Shadow" data-color="green"> I had barely let the reins slip from my fingers when a tall man stepped into the twilight, his face lined with laughter and old scars. Sir Roland wiped his gauntleted hands on a rag and offered a firm, calloused nod. "Frederick, is it?" he asked, his voice unexpectedly warm against the chill of the evening. He gestured toward the sprawling structure of the stables. "The stables are the heart of a knight's life, lad. Before you ever touch a lance, you must learn to earn the trust of the creatures who carry you into the fire. Welcome to the order." </nc-section> <nc-section data-title="The Weight of Legacy" data-color="blue"> The stables smelled of hay and ancient musk, a sharp contrast to the biting evening air. Sir Roland stood beneath a flickering lantern, his gaze fixed on the horizon rather than on me. "You carry the look of a dreamer, Squire," he remarked, his voice echoing in the rafters. He turned, his blue eyes intense, reflecting the dying light of the sun. "Many arrive here seeking glory, but the dragon fire burned out long ago, leaving only shadows in the pass. If you are to serve, know that this castle demands everything. Are you ready to see what's left of the world?" </nc-section>
