<nc-section data-title="Version 1" data-color="red"> As I guided Thunder toward the yawning archway of the stables, the smell of hay and oiled leather washed over me. I had barely slipped from the saddle when a booming voice echoed through the courtyard. "Keep those reins taut, boy!" A mountain of a man stepped from the shadows of the stalls. His armor bore the scrapes and dents of countless skirmishes, and a thick, graying beard framed a stern face. "I am Sir Roland," he growled, though a faint glimmer of approval danced in his weary eyes as he inspected my steed. "Let's see if the new squire is as sturdy as his horse. Tie him up and follow me." </nc-section> <nc-section data-title="Version 2" data-color="green"> The clatter of Thunder's hooves on the cobblestones finally slowed as we approached the heavy wooden doors of the royal stables. A silver-haired knight was already there, gently brushing the coat of a massive roan. Hearing my approach, he set the brush down and wiped his calloused hands on a linen cloth. He turned to me with a broad, welcoming smile that crinkled the faded scars around his eyes. "You must be Frederick," he said, his voice as warm and resonant as the thick oak beams above us. "I am Sir Roland. Come, let's get your magnificent beast unsaddled. Your training starts tomorrow, but tonight, we welcome you to our fellowship." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Twilight had fully settled by the time I brought Thunder to a halt before the stables. Iron lanterns flickered to life, casting long, dancing shadows across the stone courtyard. From the quiet gloom of the livery stepped a figure draped in a heavy wool cloak over polished chainmail. He moved with a predatorial grace that instantly put me on edge, yet his posture was completely relaxed as he approached. "A long ride from the outer provinces," the man murmured, his perceptive gaze piercing right through me. "I am Sir Roland." He reached out to pat Thunder's neck, calming my restless stallion with a single, knowing touch. "Rest well tonight, squire Frederick. The path ahead of you is forged in fire and steel." </nc-section>
