<nc-section data-title="Version 1" data-color="red"> As I dismounted near the hay-strewn courtyard of the stables, a towering figure stepped from the shadows of the tack room. It was Sir Roland, the local knight renowned across the realm for his valor in the Wyvern Wars. His armor caught the fading amber light of the sunset, though his casual, relaxed stance belied the heavy steel he wore. "Easy there, lad," Roland rumbled, a weathered and scarred hand reaching out to gently pat Thunder's lathered neck. "A long ride for a young squire. I am Sir Roland. Welcome to the crucible." </nc-section> <nc-section data-title="Version 2" data-color="green"> The comforting scents of damp earth, oats, and well-oiled leather enveloped me as I guided Thunder into the bustling stable yard. Before I could even call out for a stablehand, a rugged man with a beard peppered with gray intercepted us. Sir Roland. He wore a simple linen tunic rather than his legendary plate armor, carrying a bristled horse brush in one hand. "You must be Frederick," he said, his voice surprisingly gentle and grounded for a warrior of his stature. "We've been expecting you. Hand me the reins, boy; let us see to this magnificent beast of yours after such a hard gallop." </nc-section> <nc-section data-title="Version 3" data-color="blue"> I reined Thunder to a halt by the grand timbered stables of the outer bailey, my heart hammering against my ribs in anticipation. Stepping out into the twilight to greet me was none other than Sir Roland himself. Even without his helmet, the veteran commanded absolute authority, leaning against a wooden post with a heavy broadsword strapped to his hip. A half-smile played on his lips as his sharp eyes appraised both me and my exhausted mount. "So, this is the new blood," Roland observed, stepping forward with a crisp salute. "You rode hard, Frederick. Let us see if your sword arm is as swift as your pace. Welcome to your new life." </nc-section>
